环境搭建

本文初始环境为PyTorch 2.0.0、Python 3.8(ubuntu20.04)、Cuda 11.8

OpenMMLab基础环境

首先安装OpenMMLab基础环境，以下代码均在命令窗口下输入

pip install openmim
mim install mmcv-full
mim install mmcv
mim install mmdeploy_runtime

git clone https://github.com/open-mmlab/mmdetection.git
cd mmdetection
pip install -e . >> /dev/null

mkdir checkpoint
mkdir output
cd ..

mim install mmcv-full这一步需要大概15~30分钟，没报错就耐心等待。

MMDeploy环境

再次声明，下面代码均在命令窗中输入运行！！

git clone https://github.com/open-mmlab/mmdeploy.git --recursive
cd mmdeploy

# 备份镜像源
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
# 更换镜像源
sudo sed -i "s@http://.*archive.ubuntu.com@https://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list
sudo sed -i "s@http://.*security.ubuntu.com@https://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list
sudo apt-get update

python tools/scripts/build_ubuntu_x64_ort.py

更改环境变量，依然是在命令行输入

export PYTHONPATH=$(pwd)/build/lib:$PYTHONPATH
export LD_LIBRARY_PATH=$(pwd)/build/lib:$(pwd)/../mmdeploy-dep/onnxruntime-linux-x64-1.8.1/lib:$LD_LIBRARY_PATH

可以使用脚本检查环境安装状态python tools/check_env.py

YOLO-x转ONNX格式

下载YOLO-x模型的预训练权重

cd ..
cd mmdetection

# 下载YOLOX-X权重
wget https://download.openmmlab.com/mmdetection/v2.0/yolox/yolox_x_8x8_300e_coco/yolox_x_8x8_300e_coco_20211126_140254-1ef88d67.pth -P checkpoint
cd ..

使用转换脚本将YOLO-x模型转换为ONNX格式

python mmdeploy/tools/deploy.py \
    mmdeploy/configs/mmdet/detection/detection_onnxruntime_dynamic.py \
    mmdetection/configs/yolox/yolox_x_8xb8-300e_coco.py \
    mmdetection/checkpoint/yolox_x_8x8_300e_coco_20211126_140254-1ef88d67.pth \
    mmdetection/demo/demo.jpg \
    --work-dir mmdeploy_models/mmdet/yolox \
    --device cpu \
    --show \
    --dump-info

在经过上述代码后，工作目录下的文件组织信息为：

 - mmdeploy_models
     - mmdet
         - yolox
        	 - deploy.json
        	 - detail.json
        	 - end2end.onnx
        	 - pipeline.json

其中，end2end.onnx: 推理引擎文件。可用ONNX Runtime推理。*.json: mmdeploy SDK推理所需的meta 信息。

input_shape = get_input_shape(deploy_cfg)
model_inputs, _ = task_processor.create_input(image, input_shape)

with torch.no_grad():
    result = model.test_step(model_inputs)

task_processor.visualize(
    image=image,
    model=model,
    result=result[0],
    window_name='visualize',
    output_file='output_detection.png')
