|
|
|
## Installation |
|
|
|
It is recommended to use `mistralai/Mistral-7B-Instruct-v0.3` with [mistral-inference](https://github.com/mistralai/mistral-inference). For HF transformers code snippets, please keep scrolling. |
|
|
|
``` |
|
pip install mistral_inference |
|
``` |
|
|
|
## Download |
|
|
|
```py |
|
from huggingface_hub import snapshot_download |
|
from pathlib import Path |
|
|
|
mistral_models_path = Path.home().joinpath('mistral_models', '7B-Instruct-v0.3') |
|
mistral_models_path.mkdir(parents=True, exist_ok=True) |
|
|
|
snapshot_download(repo_id="mistralai/Mistral-7B-Instruct-v0.3", allow_patterns=["params.json", "consolidated.safetensors", "tokenizer.model.v3"], local_dir=mistral_models_path) |
|
``` |
|
|
|
### Chat |
|
|
|
After installing `mistral_inference`, a `mistral-chat` CLI command should be available in your environment. You can chat with the model using |
|
|
|
``` |
|
mistral-chat $HOME/mistral_models/7B-Instruct-v0.3 --instruct --max_tokens 256 |
|
``` |
|
|
|
### Instruct following |
|
|
|
```py |
|
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 |
|
|
|
|
|
tokenizer = MistralTokenizer.from_file(f"{mistral_models_path}/tokenizer.model.v3") |
|
model = Transformer.from_folder(mistral_models_path) |
|
|
|
completion_request = ChatCompletionRequest(messages=[UserMessage(content="Explain Machine Learning to me in a nutshell.")]) |
|
|
|
tokens = tokenizer.encode_chat_completion(completion_request).tokens |
|
|
|
out_tokens, _ = generate([tokens], model, max_tokens=64, temperature=0.0, eos_id=tokenizer.instruct_tokenizer.tokenizer.eos_id) |
|
result = tokenizer.instruct_tokenizer.tokenizer.decode(out_tokens[0]) |
|
|
|
print(result) |
|
``` |
|
|
|
### Function calling |
|
|
|
```py |
|
from mistral_common.protocol.instruct.tool_calls import Function, Tool |
|
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 |
|
|
|
|
|
tokenizer = MistralTokenizer.from_file(f"{mistral_models_path}/tokenizer.model.v3") |
|
model = Transformer.from_folder(mistral_models_path) |
|
|
|
completion_request = ChatCompletionRequest( |
|
tools=[ |
|
Tool( |
|
function=Function( |
|
name="get_current_weather", |
|
description="Get the current weather", |
|
parameters={ |
|
"type": "object", |
|
"properties": { |
|
"location": { |
|
"type": "string", |
|
"description": "The city and state, e.g. San Francisco, CA", |
|
}, |
|
"format": { |
|
"type": "string", |
|
"enum": ["celsius", "fahrenheit"], |
|
"description": "The temperature unit to use. Infer this from the users location.", |
|
}, |
|
}, |
|
"required": ["location", "format"], |
|
}, |
|
) |
|
) |
|
], |
|
messages=[ |
|
UserMessage(content="What's the weather like today in Paris?"), |
|
], |
|
) |
|
|
|
tokens = tokenizer.encode_chat_completion(completion_request).tokens |
|
|
|
out_tokens, _ = generate([tokens], model, max_tokens=64, temperature=0.0, eos_id=tokenizer.instruct_tokenizer.tokenizer.eos_id) |
|
result = tokenizer.instruct_tokenizer.tokenizer.decode(out_tokens[0]) |
|
|
|
print(result) |
|
``` |
|
|
|
## Generate with `transformers` |
|
|
|
If you want to use Hugging Face `transformers` to generate text, you can do something like this. |
|
|
|
```py |
|
from transformers import pipeline |
|
|
|
messages = [ |
|
{"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"}, |
|
{"role": "user", "content": "Who are you?"}, |
|
] |
|
chatbot = pipeline("text-generation", model="mistralai/Mistral-7B-Instruct-v0.3") |
|
chatbot(messages) |
|
``` |
|
|
|
|
|
## Function calling with `transformers` |
|
|
|
To use this example, you'll need `transformers` version 4.42.0 or higher. Please see the |
|
[function calling guide](https://huggingface.co/docs/transformers/main/chat_templating#advanced-tool-use--function-calling) |
|
in the `transformers` docs for more information. |
|
|
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
import torch |
|
|
|
model_id = "mistralai/Mistral-7B-Instruct-v0.3" |
|
tokenizer = AutoTokenizer.from_pretrained(model_id) |
|
|
|
def get_current_weather(location: str, format: str): |
|
""" |
|
Get the current weather |
|
|
|
Args: |
|
location: The city and state, e.g. San Francisco, CA |
|
format: The temperature unit to use. Infer this from the users location. (choices: ["celsius", "fahrenheit"]) |
|
""" |
|
pass |
|
|
|
conversation = [{"role": "user", "content": "What's the weather like in Paris?"}] |
|
tools = [get_current_weather] |
|
|
|
|
|
# format and tokenize the tool use prompt |
|
inputs = tokenizer.apply_chat_template( |
|
conversation, |
|
tools=tools, |
|
add_generation_prompt=True, |
|
return_dict=True, |
|
return_tensors="pt", |
|
) |
|
|
|
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16, device_map="auto") |
|
|
|
inputs.to(model.device) |
|
outputs = model.generate(**inputs, max_new_tokens=1000) |
|
print(tokenizer.decode(outputs[0], skip_special_tokens=True)) |
|
``` |
|
|
|
Note that, for reasons of space, this example does not show a complete cycle of calling a tool and adding the tool call and tool |
|
results to the chat history so that the model can use them in its next generation. For a full tool calling example, please |
|
see the [function calling guide](https://huggingface.co/docs/transformers/main/chat_templating#advanced-tool-use--function-calling), |
|
and note that Mistral **does** use tool call IDs, so these must be included in your tool calls and tool results. They should be |
|
exactly 9 alphanumeric characters. |
|
|
|
|
|
## Limitations |
|
|
|
The Mistral 7B Instruct model is a quick demonstration that the base model can be easily fine-tuned to achieve compelling performance. |
|
It does not have any moderation mechanisms. We're looking forward to engaging with the community on ways to |
|
make the model finely respect guardrails, allowing for deployment in environments requiring moderated outputs. |
