Function calling for LMStudio

[jaronoff97]

I'm using LMStudio with Llama hoping to use custom langchain functions with it. I can see that the tools are loaded:

TOOLS: [
  %LangChain.Function{
    name: "validate_promql",
    description: "Validate the syntax of a PromQL query. Return 'ok' or an error message.",
    display_text: nil,
    strict: false,
    function: #Function<0.126923400/2 in Intel.PromQL.Model.validate_promql_tool/0>,
    async: true,
    parameters_schema: %{
      type: "object",
      required: ["query"],
      properties: %{
        query: %{type: "string", description: "The PromQL query to validate"}
      }
    },
    parameters: []
  }
]

and that the model attempts to call the function, but it's trying it via python?

SINGLE MESSAGE RESPONSE: %LangChain.Message{
  content: "<|python_tag|>{\"type\": \"function\", \"function\": {\"name\": \"validate_promql\", \"parameters\": {\"query\": \"rate(last(accepted_metrics) by item)\"}}",
  processed_content: nil,
  index: 0,
  status: :complete,
  role: :assistant,
  name: nil,
  tool_calls: [],
  tool_results: nil,
  metadata: nil
}

Is there something custom i need to do in LMStudio or langchain to make this work?
