1. Yolov7 Prerequisite

cd yolov7
pip3 install -r requirements.txt

2. Convert Pytorch model to ONNX

Remember to change the variable to your setting.

python3 pytorch2onnx.py --weights ./model/yolov7-tiny.pt --simplify --img-size 480 640 --max-wh 640 --topk-all 100 --end2end --grid

3. RKNN Prerequisite

Install the wheel according to your python version

cd rknn-toolkit2/packages
pip3 install rknn_toolkit2-1.5.0+1fa95b5c-cpxx-cpxx-linux_x86_64.whl

4. Modify ONNX network structure

Install ONNX modifier and start flask service

cd onnx-modifier
pip3 install -r requirements.txt
pip3 install onnx==1.10.0
python3 app.py

Enter http://127.0.0.1:5000/ Cut the below part of the network

Add the new output and download it

Move the modified newtork to replace the old one

mv ./onnx-modifier/modified_onnx/modified_{model_name}-{input_height}-{input_width}.onnx ./model/{model_name}-{input_height}-{input_width}.onnx

5. Convert ONNX model to RKNN

Remember to change the variable to your setting To improve perfermance, you can change ./config/yolov7-seg-xxx-xxx.quantization.cfg layer type. Please follow official document hybrid quatization part and reference to example program to modify your codes.

python3 onnx2rknn_step1.py
python3 onnx2rknn_step2.py

6. RKNN-Lite Inference

python3 rknn_lite_inference.py

7. Horizon Prerequisite

wget -c ftp://[email protected]/ai_toolchain/ai_toolchain.tar.gz --ftp-password=xj3ftp@123$%
tar -xvf ai_toolchain.tar.gz
cd ai_toolchain/
pip3 install h*

7. Convert ONNX model to Horizon

get onnx file with opset 11

python3 pytorch2onnx.py --weights ./model/yolov7-tiny.pt --simplify --img-size 480 640 --max-wh 640 --topk-all 100 --end2end --grid --opset 11

Follow Step 4 to delete part of model, and run remove_value_list.py to remove corresponding value in model Remember to change the variable to your setting include yolov7det_config.yaml

sh 01_check.sh
sh 02_preprocess.sh
sh 03_build.sh

8. Horizon Inference

python3 horizion_simulator_inference.py
python3 horizion_onboard_inference.py

9. Onnx Runtime Inference

python3 onnxruntime_inference.py

10. Convert ONNX model to TensorRT

Use the ONNX file come from Step 4
Remember to change the variable to your setting

python3 onnx2trt.py

11. TensorRT Inference

python3 tensorrt_inference.py

12. Blob Inference

Convert model from onnx to blob format via https://blobconverter.luxonis.com/

python3 blob_inference.py
