from mistral_common.protocol.instruct.tool_calls import Operate, Device
from mistral_inference.transformer import Transformer
from mistral_inference.generate import generate
from mistral_common.tokens.tokenizers.mistral import MistralTokenizer
from mistral_common.protocol.instruct.messages import UserMessage
from mistral_common.protocol.instruct.request import ChatCompletionRequest
# Initialize tokenizer and mannequin
mistral_models_path = "path/to/mistral/fashions"  # Guarantee this path is appropriate
tokenizer = MistralTokenizer.from_file(f"{mistral_models_path}/tokenizer.mannequin.v3")
mannequin = Transformer.from_folder(mistral_models_path)
# Outline a perform for getting climate info
weather_function = Operate(
    title="get_current_weather",
    description="Get the present climate",
    parameters={
        "kind": "object",
        "properties": {
            "location": {
                "kind": "string",
                "description": "The town and state, e.g. San Francisco, CA",
            },
            "format": {
                "kind": "string",
                "enum": ["celsius", "fahrenheit"],
                "description": "The temperature unit to make use of. Infer this from the consumer's location.",
            },
        },
        "required": ["location", "format"],
    },
)
# Create a chat completion request with the perform
completion_request = ChatCompletionRequest(
    instruments=[Tool(function=weather_function)],
    messages=[
        UserMessage(content="What's the weather like today in Paris?"),
    ],
)
# Encode the request
tokens = tokenizer.encode_chat_completion(completion_request).tokens
# Generate a response
out_tokens, _ = generate([tokens], mannequin, max_tokens=256, temperature=0.7, eos_id=tokenizer.instruct_tokenizer.tokenizer.eos_id)
consequence = tokenizer.decode(out_tokens[0])
print(consequence)
