Implement Token Counting Method for AnthropicBedrock

Medium Risk

The error occurs because the 'AnthropicBedrock' class does not have a method named 'count_tokens'. This indicates that the functionality to count tokens has not been implemented in the class, leading to the AttributeError when attempting to call this method.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Define count_tokens Method

    Add a method named 'count_tokens' to the 'AnthropicBedrock' class. This method should accept a string input and return the number of tokens in that string based on the tokenization rules used by the model.

    python
    def count_tokens(self, text):
        # Example tokenization logic, adjust based on actual model requirements
        return len(text.split())
  2. 2

    Update Class Definition

    Ensure that the 'count_tokens' method is included in the class definition of 'AnthropicBedrock'. This will make the method available for instances of the class.

    python
    class AnthropicBedrock:
        def __init__(self):
            pass
    
        def count_tokens(self, text):
            return len(text.split())
  3. 3

    Test the count_tokens Method

    Create unit tests to verify that the 'count_tokens' method works correctly. Test with various input strings to ensure accurate token counting.

    python
    def test_count_tokens():
        bedrock = AnthropicBedrock()
        assert bedrock.count_tokens('Hello world') == 2
        assert bedrock.count_tokens('This is a test') == 4
  4. 4

    Document the New Method

    Update the documentation for the 'AnthropicBedrock' class to include details about the 'count_tokens' method, including its parameters and return value.

Validation

Run the unit tests created in step 3. If all tests pass without errors, the implementation is confirmed to be successful. Additionally, manually test the 'count_tokens' method with various strings to ensure it returns the expected token counts.
