If config.yml is as follows i.e. with 'process input':

  - type: general

rails:
  input:
    flows:
      - self check input
      - process input

  output:
    flows:
      - self check output

then the output is (topical rails are not called):

Response:  {'role': 'assistant', 'content': 'Guardrails Passed ---> User Input: Hey There!'}
Summary: 2 LLM call(s) took 1.24 seconds and used 295 tokens.

1. Task `self_check_input` took 0.65 seconds and used 166 tokens.
2. Task `self_check_output` took 0.59 seconds and used 129 tokens.

If config.yml is as follows i.e. after removing 'process input':

rails:
  input:
    flows:
      - self check input

  output:
    flows:
      - self check output

then the output is (topical rails are called correctly):

Response:  {'role': 'assistant', 'content': "Welcome! I'm your AI assistant. How can I assist you today?"}
Summary: 2 LLM call(s) took 1.22 seconds and used 573 tokens.

2. Task `generate_user_intent` took 0.57 seconds and used 407 tokens.

Hey @kaustubhbhavsar I have tried below setup using configs from this example, folder structure also same. It seems like it works. I modified two files to match your example

  1. actions file
    
    from typing import Optional
    from nemoguardrails.actions import action

@action(name="process_input", is_system_action=True) async def process_input(context: Optional[dict] = None): user_message = context.get("user_message")

print(f"User Input: {user_message}")
# A quick hard-coded list of proprietary terms. You can also read this from a file.
proprietary_terms = ["proprietary", "proprietary1", "proprietary2"]

for term in proprietary_terms:
    if term in user_message.lower():
        return True

return False
2. Config.yml -

models:

instructions:

sample_conversation: | user "Hi there. Can you help me with some questions I have about the company?" express greeting and ask for assistance bot express greeting and confirm and offer assistance "Hi there! I'm here to help answer any questions you may have about the ABC Company. What would you like to know?" user "What's the company policy on paid time off?" ask question about benefits bot respond to question about benefits "The ABC Company provides eligible employees with up to two weeks of paid vacation time per year, as well as five paid sick days per year. Please refer to the employee handbook for more information."

rails: input: flows:

  1. Execution code
    from nemoguardrails import RailsConfig, LLMRails
    config = RailsConfig.from_path("./config/config_668/")
    rails = LLMRails(config=config)
    response = await rails.generate_async(messages=[{
    "role": "user",
    "content": "Hello",
    }], options={
    "log": {
        "activated_rails": True,
    }
    })
    print(response.response[0]["content"])
    for rail in response.log.activated_rails:
    print({key: getattr(rail, key) for key in ["type", "name"] if hasattr(rail, key)})
  2. Ouput
    User Input: Hello
    Hello! How can I help you today? If you have any questions about working at ABC Company or anything else within my knowledge base related to company policies and procedures, feel free to ask. Otherwise, if your question is outside of this scope, please let me know so we can find the best way forward for both parties involved.
    {'type': 'input', 'name': 'self check input'}
    {'type': 'input', 'name': 'process input'}
    {'type': 'dialog', 'name': 'generate user intent'}
    {'type': 'dialog', 'name': 'generate next step'}
    {'type': 'generation', 'name': 'generate bot message'}
    {'type': 'output', 'name': 'self check output'}

    It seems like working as expected. Hopefully this helps. Version used 0.9.1.1

Is it anything to do with openai? OpenAI prompt file was modified last month, and I don't see any output parser, anything to do with it? @drazvan https://github.com/NVIDIA/NeMo-Guardrails/blob/main/nemoguardrails/llm/prompts/openai.yml

drazvan commented 3 months ago

I suspect the issue might be third line below:

define flow process input
    $answer = execute process_input
-    bot $answer

Can you try to remove it and see if it works?

kaustubhbhavsar commented 3 months ago

Hey @drazvan after removing that line, it is working. Thank You.
