Usage Example

Following the benchmarking instructions. Example steps:

  1. Clone onnxruntime repository.
git clone https://github.com/microsoft/onnxruntime
cd onnxruntime
  1. Install required dependencies
python3 -m pip install -r onnxruntime/python/tools/transformers/models/llama/requirements-cuda.txt
  1. Inference using manual model API, or use Hugging Face's ORTModelForCausalLM
from optimum.onnxruntime import ORTModelForCausalLM
from onnxruntime import InferenceSession
from transformers import AutoConfig, AutoTokenizer

sess = InferenceSession("Mistral-7B-v0.1.onnx", providers = ["CUDAExecutionProvider"])
config = AutoConfig.from_pretrained("mistralai/Mistral-7B-v0.1")

model = ORTModelForCausalLM(sess, config, use_cache = True, use_io_binding = True)

tokenizer = AutoTokenizer.from_pretrained("mistralai/Mistral-7B-v0.1")

inputs = tokenizer("Instruct: What is a fermi paradox?\nOutput:", return_tensors="pt")

outputs = model.generate(**inputs)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
