# Apps examples with GenerationExecutor / LLM API
|
|
## Python chat
|
|
|
|
[chat.py](./chat.py) provides a small examples to play around with your model. Before running, install additional requirements with ` pip install -r ./requirements.txt`. Then you can run it with
|
|
|
|
```
|
|
python3 ./chat.py --model <model_dir> --tokenizer <tokenizer_path> --tp_size <tp_size>
|
|
```
|
|
|
|
Please run `python3 ./chat.py --help` for more information on the arguments.
|
|
|
|
Note that, the `model_dir` could accept the following formats:
|
|
|
|
1. A path to a built TRT-LLM engine
|
|
2. A path to a local HuggingFace model
|
|
3. The name of a HuggingFace model such as "TinyLlama/TinyLlama-1.1B-Chat-v1.0"
|
|
|
|
## FastAPI server
|
|
|
|
NOTE: This FastAPI-based server is only an example for demonstrating the usage
|
|
of TensorRT-LLM LLM API. It is not intended for production use.
|
|
For production, use the `trtllm-serve` command. The server exposes OpenAI compatible API endpoints.
|
|
|
|
### Install the additional requirements
|
|
|
|
```
|
|
pip install -r ./requirements.txt
|
|
```
|
|
|
|
### Start the server
|
|
|
|
Start the server with:
|
|
|
|
```
|
|
python3 ./fastapi_server.py <model_dir>&
|
|
```
|
|
|
|
Note that, the `model_dir` could accept same formats as in the chat example. If you are using an engine build with `trtllm-build`, remember to pass the tokenizer path:
|
|
|
|
```
|
|
python3 ./fastapi_server.py <model_dir> --tokenizer <tokenizer_dir>&
|
|
```
|
|
|
|
To get more information on all the arguments, please run `python3 ./fastapi_server.py --help`.
|
|
|
|
### Send requests
|
|
|
|
You can pass request arguments like "max_tokens", "top_p", "top_k" in your JSON dict:
|
|
```
|
|
curl http://localhost:8000/generate -d '{"prompt": "In this example,", "max_tokens": 8}'
|
|
```
|
|
|
|
You can also use the streaming interface with:
|
|
```
|
|
curl http://localhost:8000/generate -d '{"prompt": "In this example,", "max_tokens": 8, "streaming": true}'
|
|
```
