I have given the app.py file and config.yml(inside config folder) file as follows

app.py

from nemoguardrails import RailsConfig, LLMRails

config = RailsConfig.from_path("./config")
rails = LLMRails(config)

response = rails.generate(messages=[{
    "role": "user",
    "content": "Hello! What can you do for me?"
}])
print(response["content"])

config.yml file

models:
  type: main
  engine: azure
  model: <model name>
  parameters:
      azure_endpoint: <base URL>
      api_version: <version name>
      deployment_name: <model name>
      api_key: <API KEY>

instructions:
  - type: general
    content: |

@pradeepdev-1995: The syntax is incorrect, inside the YAML file. The models key should be an array. You're missing a dash:

models:
- type: main
  engine: azure
  model: <model name>
  parameters:
      azure_endpoint: <base URL>
      api_version: <version name>
      deployment_name: <model name>
      api_key: <API KEY>
