\nExample 1:
Question: What are the fat-soluble vitamins?
Answer: The fat-soluble vitamins include Vitamin A, Vitamin D, Vitamin E, and Vitamin K. These vitamins are absorbed along with fats in the diet and can be stored in the body's fatty tissue and liver for later use. Vitamin A is important for vision, immune function, and skin health. Vitamin D plays a critical role in calcium absorption and bone health. Vitamin E acts as an antioxidant, protecting cells from damage. Vitamin K is essential for blood clotting and bone metabolism.
\nExample 2:
Question: What are the causes of type 2 diabetes?
Answer: Type 2 diabetes is often associated with overnutrition, particularly the overconsumption of calories leading to obesity. Factors include a diet high in refined sugars and saturated fats, which can lead to insulin resistance, a condition where the body's cells do not respond effectively to insulin. Over time, the pancreas cannot produce enough insulin to manage blood sugar levels, resulting in type 2 diabetes. Additionally, excessive caloric intake without sufficient physical activity exacerbates the risk by promoting weight gain and fat accumulation, particularly around the abdomen, further contributing to insulin resistance.
\nExample 3:
Question: What is the importance of hydration for physical performance?
Answer: Hydration is crucial for physical performance because water plays key roles in maintaining blood volume, regulating body temperature, and ensuring the transport of nutrients and oxygen to cells. Adequate hydration is essential for optimal muscle function, endurance, and recovery. Dehydration can lead to decreased performance, fatigue, and increased risk of heat-related illnesses, such as heat stroke. Drinking sufficient water before, during, and after exercise helps ensure peak physical performance and recovery."""

is this the right prompt formatting for meta-llama/Llama-3.1-8B-Instruct

思考

Analyzing code

I'm thinking through the request, which involves understanding the Python code to ensure it meets the formatting standards for specific models while adhering to policy.

Verifying prompt formatting

I’m confirming if the PromptManager class accurately ensures the correct formatting of prompts. This involves ensuring the use of system prompts, context items, and questions without any disallowed content.

Mapping out parts

I'm thinking through the use of [INST] tokens and system prompts for Llama 2 models, while also considering how to format prompts for the meta-llama/Llama-3.1-8B-Instruct model.

Handling prompt formatting

I’m examining the PromptManager class and noticed it’s responsible for managing prompt construction and formatting.

Understanding the causes

Type 2 diabetes is mainly tied to overnutrition, with high refined sugar and saturated fat intake causing insulin resistance and weight gain.

Crafting a context-rich prompt

I’m generating context-rich prompts by embedding questions and details within brackets, ensuring a clear and engaging explanation.

Aligning the prompt format

I'm digging into Meta AI's Llama-2 prompt format. It seems the code might lack the closing [/INST] token, suggesting a need for alignment.

Crafting the prompt

I’m working on optimizing the Llama-2 prompt format, ensuring system and user instructions are accurately enclosed for accurate responses.

Refining prompt formatting

I’m thinking through how to tweak the format_prompt method. The crucial change is adding the [/INST] token at the end to clearly separate the user's input from the assistant's response.

回答

Yes, your prompt formatting is close to the expected format for the meta-llama/Llama-3.1-8B-Instruct model, which follows the prompt structure used by Llama 2. However, there is a small adjustment needed to align it perfectly with the model's expected input format.

In the Llama 2 prompt format, the user's instruction is enclosed between [INST] and [/INST] tokens, with the system prompt placed within <<SYS>> and <</SYS>>. The assistant's response is expected to follow immediately after the closing [/INST] token. In your current format_prompt method, you're missing the closing [/INST] token, which is essential for the model to correctly interpret where the user's input ends and the assistant's response should begin.

Here's how you can modify your format_prompt method to include the [/INST] token:

python
def format_prompt(self, question: str, context_items: List[str]) -> str: """Format prompt with question""" context = "- " + "\n- ".join(context_items) return f"""[INST] <<SYS>> {self.system_prompt} <</SYS>> Now use the following context items to answer the user query. Context: {context} Question: {question} Answer: [/INST]"""

Explanation of Changes:

  • Added the [/INST] Token: Including the closing [/INST] token signals the end of the user's instruction and is crucial for the model to generate the assistant's response appropriately.
  • Formatting Adjustments: Added newlines for better readability and to ensure the prompt tokens are properly separated from the content.

Additional Recommendations:

  • Consistency in Formatting: Ensure that there are blank lines separating the tokens ([INST], <<SYS>>, <</SYS>>, and [/INST]) and the content for clarity.
  • System Prompt Length: While examples can be helpful, be mindful of the prompt's total length. Extremely long prompts might approach the model's context window limits, potentially affecting performance. Consider summarizing or shortening the examples if necessary.
  • Context Items Formatting: Make sure that the context items are relevant and clearly formatted to aid the model in generating accurate responses.

By making these adjustments, your prompt should be correctly formatted for the meta-llama/Llama-3.1-8B-Instruct model, allowing it to generate responses that are aligned with your expectations.

Reviewing the prompt

Pop over to see the PromptManager class and the code's functionality. The key insight is recognizing the need for the [INST] ... [/INST] format. Adjust the prompt as necessary to align with this requirement.

Taking a closer look

Evaluating prompt structure

I noticed the assistant's response appended extra tokens, likely violating the prompt format. The data needed confirming whether adding the closing [/INST] token was correct, as the instruction should be enclosed between [INST] and [/INST].

Correcting prompt formatting

I’m noting that the model's output errors stem from incorrect prompt formatting, indicated by elements like [INST] and <<SYS>>. Adjusting the prompt and verifying its accuracy will improve clarity and functionality.

Identifying the gap

I’m examining the model's response and noticing the inclusion of parsing elements like [INST] and <<SYS>> in the output. This suggests the model isn't correctly separating the user's instruction from the assistant's response.

回答

Based on the data you provided, it appears that the model is not correctly interpreting the prompt, which results in the generated output including prompt tokens like [INST], <<SYS>>, and <</SYS>>. This indicates that the model is not recognizing where the user's input ends and where it should begin generating its response.

In your original prompt, the closing [/INST] token is missing. According to the expected prompt format for meta-llama/Llama-3.1-8B-Instruct (which follows the Llama 2 prompt structure), the user's instruction should be enclosed between [INST] and [/INST]. The assistant's response should come immediately after the closing [/INST] token.

Here's the issue in your provided data:

  • Missing [/INST] Token: Without the closing [/INST], the model doesn't have a clear signal to stop reading the prompt and start generating the response. This can cause it to include the prompt tokens in its output.

  • Model Output Includes Prompt Tokens: The generated answer repeats the prompt tokens and system messages, which suggests confusion in the model's parsing of the input.

By adding the closing [/INST] token, you clearly define the boundary between the user's input and the assistant's expected response. This helps the model properly interpret the prompt and generate a clean answer without including the prompt formatting elements.

Conclusion:

Yes, the modification I suggested—adding the closing [/INST] token—is the correct approach. The data you provided confirms that without this token, the model does not process the prompt as intended. Implementing this change should result in the model generating appropriate responses without echoing the prompt tokens.

Revised format_prompt Method:

To ensure proper formatting, your format_prompt method should be updated as follows:

python
def format_prompt(self, question: str, context_items: List[str]) -> str: """Format prompt with question""" context = "- " + "\n- ".join(context_items) return f"""[INST] <<SYS>> {self.system_prompt} <</SYS>> Now use the following context items to answer the user query. Context: {context} Question: {question} Answer: [/INST]"""

Key Changes:

  • Added the [/INST] Token: This clearly signals the end of the user's instruction.

  • Formatting Adjustments: Proper spacing and newlines ensure that the model can parse the prompt correctly.

By making these adjustments, you should find that the model generates responses that are properly formatted and aligned with your expectations.

When they followed up after several years, the individuals who had given up napping had seen a 37 percent increase in their risk of dying from heart disease. For working men, it was an over 60 percent increase.
  • The groggy feeling upon awakening from a nap might be a deterrent for even an ardent napper. This is sleep inertia, and with a more regular napping routine, it will be easily managed. Knowing you will have that sensation and that it will pass, usually within ten minutes, will make it easier to settle down for the nap. Some people who enjoy caff eine, and have• Sleep Wellness: Napping tested to be sure it is not aff ecting their nighttime sleep, might want to have some right before their nap or immediately upon waking to help manage sleep inertia, but this isn’t always necessary. The quality of clear and relaxed energy that takes you well into the evening, as opposed to the energy crash from not napping and using caff eine or nico- tine in place of a nap, is usually enough to motivate someone to maintain a napping habit. Since the body has not been on a roller coaster of drowsi- ness during the day, thanks to the missed nap and possibly the use of stimulants, it approaches bed- time in a more even and restful state, and a better night’s sleep should follow. Students hoping to optimize their study eff orts would be wise to close the book and take a short nap (fi gure 1.4). Naps increase memory performance, and scientists have documented particular types of brain activity that are associated with enhanced learning during naps, including sleep spindles (see chapter 2). When working on a homework set, the skill of restructuring— viewing a problem from various perspectives and creating a novel vision— is an ingredient for success that can be obtained via a brief afternoon snooze.

When trying to avoid a cold or the fl u, people are willing to spend a lot of money on immune support supplements and vitamins, but one of the stron- gest ways to provide powerful immune support is free (fi gure 1.5). After a night of poor sleep, anti- viral molecules such as interleukin- 6 drop and reduce immune system power. However, a nap can bring those levels back to normal. Researchers have also found increased levels of norepineph- rine, the “fi ght or fl ight” molecule, after reduced nighttime sleep. Sustained high levels of norepi- nephrine, associated with the stress response, have harmful eff ects on blood glucose balance and cardiovascular health.

回答

I'm sorry to hear that you're still experiencing issues with the prompt formatting. Based on the output you provided, it seems that the model is still including prompt tokens like [INST] and <<SYS>> in its response. This indicates that the model isn't correctly interpreting where the user's input ends and where it should begin generating its response.

Possible Reasons:

  1. Length and Complexity of the System Prompt:
    • Including extensive examples within the system prompt can sometimes confuse the model. The system prompt is intended to set the overall behavior and guidelines for the assistant, and overly long prompts might cause the model to include parts of it in its output.
  2. Placement of Examples:
    • Placing examples inside the system prompt may lead the model to think that reproducing or referencing them is part of the desired output.
  3. Formatting of Tokens:
    • Incorrect placement or formatting of special tokens like [INST], <<SYS>>, <</SYS>>, and [/INST] can cause the model to misinterpret the prompt structure.

Recommendations:

To resolve this issue, I suggest the following adjustments to your prompt formatting:


1. Simplify the System Prompt:

Keep the system prompt concise and focused on the assistant's behavior without including lengthy examples.

python
self.system_prompt = """Please answer the user's question based on the provided context. Extract relevant information from the context to form your answer. Do not include any of your thought processes in the final answer. Keep your response to 2 or 3 sentences."""

2. Move Examples into the User Message:

Include the examples as part of the user message instead of the system prompt. This helps the model treat them as reference material rather than instructions to reproduce.


3. Adjust the Prompt Formatting:

Here's how you can modify your format_prompt method:

python
def format_prompt(self, question: str, context_items: List[str]) -> str: """Format prompt with question and context""" context = "- " + "\n- ".join(context_items) examples = """Example 1: Question: What are the fat-soluble vitamins? Answer: The fat-soluble vitamins include Vitamin A, Vitamin D, Vitamin E, and Vitamin K. These vitamins are absorbed along with fats in the diet and can be stored in the body's fatty tissue and liver for later use. Example 2: Question: What are the causes of type 2 diabetes? Answer: Type 2 diabetes is often associated with overconsumption of calories leading to obesity. Factors include a diet high in refined sugars and saturated fats, which can lead to insulin resistance. Example 3: Question: What is the importance of hydration for physical performance? Answer: Hydration is crucial for physical performance because it maintains blood volume, regulates body temperature, and ensures the transport of nutrients and oxygen to cells. """ user_message = f"""{examples} Now, please answer the following question using the context provided. Context: {context} Question: {question} Answer:""" return f"""[INST] <<SYS>> {self.system_prompt} <</SYS>> {user_message} [/INST]"""

Explanation:

  • Simplified System Prompt: The system prompt is now concise, focusing on the assistant's behavior.
  • Examples in User Message: By moving the examples into the user message, you help the model see them as reference material rather than instructions to reproduce.
  • Clear Formatting: Ensures that special tokens are correctly placed without extra spaces or lines that might confuse the model.

4. Verify Token Placement and Formatting:

Ensure that:

  • The [INST] token starts at the very beginning of the prompt without any leading spaces or newlines.
  • The [/INST] token is on its own line immediately after the user's message.
  • There are no extra spaces or newlines between tokens and content.

5. Test with a Simplified Prompt:

To check if the issue persists due to other factors, try using a simplified prompt without context or examples:

python
def format_prompt(self, question: str) -> str: """Format prompt with question only""" user_message = f"""Question: {question} Answer:""" return f"""[INST] <<SYS>> {self.system_prompt} <</SYS>> {user_message} [/INST]"""

If the model responds correctly to this prompt, gradually add the context and examples back in, testing at each step to identify where the issue arises.


6. Be Mindful of Prompt Length:

Long prompts can sometimes cause the model to exceed its context window or become confused. If possible, try to shorten the context items or examples.


Conclusion:

By simplifying the system prompt and carefully structuring the prompt with correct token placement, you should be able to prevent the model from including prompt tokens in its output. Moving the examples into the user message helps the model treat them as part of the conversation rather than instructions to replicate.

Additional Tips:

  • Consistency: Always use consistent formatting for special tokens and messages.
  • Model Documentation: Refer to the model's documentation for any specific prompt formatting guidelines.
  • Experimentation: Small changes can have significant effects. Don't hesitate to experiment with different prompt structures to see what works best.

回答

I understand that you're still experiencing issues where the model includes prompt tokens like [/INST] and <<SYS>> in its output, and it keeps repeating the answer in a loop. Let's analyze why this is happening and how to fix it.


Issue Analysis

1. Inclusion of Prompt Tokens in Output:

  • The model is outputting special tokens ([/INST], <<SYS>>, etc.) in its response.
  • This suggests that the model is not recognizing these tokens as structural elements but is treating them as part of the content to generate.

2. Repetition and Looping:

  • The model repeats the answer multiple times with the tokens interleaved.
  • This behavior indicates the model might be confused about when to stop generating, possibly due to the way the prompt is structured.

Possible Causes

A. Incorrect Prompt Formatting:

  • The special tokens ([INST], <<SYS>>, etc.) might not be placed correctly according to the model's expected format.
  • The model may not support or expect these tokens in the way they're being used.

B. Model's Training Data and Tokenization:

  • If the model wasn't trained with these specific tokens, it might not recognize them as special instructions.
  • The tokenizer might not be handling these tokens correctly, causing them to be treated as regular text.

C. Overloading the System Prompt:

  • Including lengthy examples in the system prompt can confuse the model.
  • The model might attempt to reproduce the examples or include parts of the system prompt in its output.

Recommendations

To resolve this issue, let's adjust the prompt formatting and simplify the content to align better with the model's capabilities.


1. Simplify the System Prompt

Current System Prompt:

Your current system prompt is lengthy and includes multiple examples. While examples can be helpful, placing them within the system prompt might cause the model to include them in the output.

Action:

  • Simplify the system prompt to focus on instructions only.
  • Move the examples into the user's message or omit them if not necessary.

Revised System Prompt:

python
self.system_prompt = """Please answer the user's question based on the provided context. Extract relevant information from the context to form your answer. Do not include any of your thought processes in the final answer. Keep your response to 2 or 3 sentences."""

2. Remove Special Tokens

Given that the model is including tokens like [/INST] and <<SYS>> in its output, it's possible that the model doesn't interpret these tokens as structural elements.

Action:

  • Remove the special tokens ([INST], <<SYS>>, [/INST], etc.) from your prompt.
  • Use a simple prompt structure without these tokens.

Revised format_prompt Method:

python
def format_prompt(self, question: str, context_items: List[str]) -> str: """Format prompt with question and context""" context = "- " + "\n- ".join(context_items) examples = """Example 1: Question: What are the fat-soluble vitamins? Answer: [Short Answer] Example 2: Question: What are the causes of type 2 diabetes? Answer: [Short Answer] Example 3: Question: What is the importance of hydration for physical performance? Answer: [Short Answer] """ prompt = f"""{self.system_prompt} {examples} Please answer the following question using the context provided. Context: {context} Question: {question} Answer:""" return prompt

3. Ensure Clear Separation of Instructions and Content

Action:

  • Place examples in the user message, not in the system prompt.
  • Ensure that the prompt has clear sections for instructions, examples, context, and the question.

4. Test with a Simplified Prompt

Before adding complexity, test the model with a minimal prompt to see if it generates the expected output.

Minimal Prompt Example:

python
def format_prompt(self, question: str) -> str: """Format prompt with question only""" prompt = f"""Please answer the following question concisely. Question: {question} Answer:""" return prompt

Action:

  • Test this simple prompt to see if the model stops including prompt tokens in the output.
  • If it works, gradually add back the context and other elements, ensuring the model continues to behave correctly.

5. Verify Tokenization and Model Compatibility

Action:

  • Ensure that you're using the correct tokenizer for the model.
  • Check if the model supports or requires special tokens, and adjust accordingly.

6. Review Model Documentation

Different models may have different expected prompt formats.

Action:

  • Consult the meta-llama/Llama-3.1-8B-Instruct model's documentation to verify the correct prompt format.
  • Adjust your prompt to match any specific requirements outlined in the documentation.

7. Avoid Overloading the Prompt

Long prompts with extensive examples and context can overwhelm the model.

Action:

  • Keep the prompt concise.
  • Limit the number of examples or shorten them.
  • Ensure the context is relevant and necessary for answering the question.

Putting It All Together

Here's a revised version of your PromptManager class with the suggested changes:

python
class PromptManager: """Handles prompt construction and formatting""" def __init__(self): self.system_prompt = """Please answer the user's question based on the provided context. Extract relevant information from the context to form your answer. Do not include any of your thought processes in the final answer. Keep your response to 2 or 3 sentences.""" def format_prompt(self, question: str, context_items: List[str]) -> str: """Format prompt with question and context""" context = "- " + "\n- ".join(context_items) examples = """Example 1: Question: What are the fat-soluble vitamins? Answer: The fat-soluble vitamins include Vitamins A, D, E, and K, which are absorbed with dietary fats and can be stored in the body's fatty tissue and liver. Example 2: Question: What are the causes of type 2 diabetes? Answer: Type 2 diabetes is often caused by insulin resistance due to factors like obesity, lack of physical activity, and a diet high in refined sugars and saturated fats. Example 3: Question: What is the importance of hydration for physical performance? Answer: Hydration is crucial for maintaining blood volume, regulating body temperature, and allowing muscle contractions, all of which are essential for optimal physical performance. """ prompt = f"""{self.system_prompt} {examples} Please answer the following question using the context provided. Context: {context} Question: {question} Answer:""" return prompt def set_system_prompt(self, new_system_prompt: str) -> None: self.system_prompt = new_system_prompt

Example Output

With the revised prompt, the model should focus on generating the answer without including special tokens or repeating itself.

Expected Model Output:

Napping offers several benefits, including improved memory performance, increased motor learning, and enhanced creativity. It helps regulate blood pressure, boosts immune function by normalizing anti-viral molecules like interleukin-6, and reduces the risk of heart disease. Additionally, napping can manage sleep inertia and promote better nighttime sleep quality.

Additional Tips

  • Monitor the Length of the Context: Ensure the context provided is within the model's context window to prevent truncation or confusion.
  • Avoid Unnecessary Complexity: The simpler the prompt, the less likely the model is to misinterpret it.
  • Iterative Testing: Test the prompt after each change to see how the model responds.

Conclusion

By simplifying your prompt and removing special tokens, you should be able to prevent the model from including those tokens in its output and avoid repetitive answers. Always tailor your prompt to the specific requirements and capabilities of the model you're using.
