1.安装onnxruntime-gpu

新版的onnxruntime-gpu 即支持gpu的推理,也支持cpu的推理。

卸载旧的1.7.1 cpu版本,安装新的gpu版本:

pip uninstall onnxruntime
pip install onnxruntime-gpu

检查是否安装成功:

>>> import onnxruntime
>>> onnxruntime.__version__
'1.10.0'
>>> onnxruntime.get_device()
'GPU'
>>> onnxruntime.get_available_providers()
['TensorrtExecutionProvider', 'CUDAExecutionProvider', 'CPUExecutionProvider']

2.修改推理代码

在推理代码上增加 providers参数,选择推理的框架。看自己支持哪个就选择自己支持的就可以了。

session = onnxruntime.InferenceSession('yolov5s.onnx', None)
# 改为:
session = onnxruntime.InferenceSession('yolov5s.onnx', 
        providers=['TensorrtExecutionProvider', 'CUDAExecutionProvider', 'CPUExecutionProvider'])

如果运行推理代码出现 Tensorrt, CUDA都无法推理,如下所示,则是自己的 ONNX Runtime, TensorRT, CUDA 版本没对应正确 。

Please reference https://onnxruntime.ai/docs/execution-providers/TensorRT-ExecutionProvider.html#requirements to ensure all dependencies are met.

对应版本如下 :

1fc9c482 ### Description Enable coremltools for Linux build. In order to do this, I did: 1. Add uuid-devel to the Linux images and regenerate them. 2. Patch the coremltools code a little bit to add some missing header files. ### Motivation and Context To make the code simpler. Later on I will create another PR to remove the COREML_ENABLE_MLPROGRAM C/C++ macro. Also, after this PR I will bring more changes to onnxruntime_provider_coreml.cmake to make it work with vcpkg. 2 天前
