Ollama Fails When Tools Use Optional Args

by ADMIN 42 views

Introduction

Ollama is a powerful tool for generating text based on user input. However, when using Ollama with the model llama3.1, users may encounter an error related to optional arguments. In this article, we will explore the issue and provide a solution to resolve the problem.

Understanding the Error

The error message indicates that there is a KeyError when trying to access the 'type' key in the prop_schema dictionary. This error occurs in the _process_create_args method of the _ollama_client class.

create_params = self._process_create_args(
    # ...
)

The _process_create_args method calls the convert_tools function to convert the tools argument into a format that can be used by Ollama.

converted_tools = convert_tools(tools)

The convert_tools function is responsible for converting the tools argument into a format that can be used by Ollama. However, when the tools argument contains optional arguments, the convert_tools function fails to convert them correctly, resulting in a KeyError.

The Root Cause of the Issue

The root cause of the issue is related to the way Ollama handles optional arguments. When using Ollama with the model llama3.1, the tools argument may contain optional arguments that are not present in the prop_schema dictionary. In this case, the convert_tools function fails to convert the optional arguments correctly, resulting in a KeyError.

The Solution

To resolve the issue, we need to modify the convert_tools function to handle optional arguments correctly. We can do this by adding a check to see if the optional argument is present in the prop_schema dictionary before trying to access it.

def convert_tools(tools):
    converted_tools = []
    for tool in tools:
        if 'type' in tool:
            converted_tools.append(tool)
        elif 'optional' in tool and tool['optional']:
            # Handle optional arguments correctly
            if 'type' in tool['optional']:
                converted_tools.append(tool)
    return converted_tools

Modifying the Ollama Client

To apply the solution, we need to modify the Ollama client to use the modified convert_tools function. We can do this by updating the _process_create_args method to use the modified convert_tools function.

def _process_create_args(self, tools):
    converted_tools = convert_tools(tools)
    # ...

Conclusion

In conclusion, the issue with Ollama failing when tools use optional args is related to the way Ollama handles optional arguments. By modifying the convert_tools function to handle optional arguments correctly, we can resolve the issue and use Ollama with the model llama3.1 without encountering errors.
