Usage

Pytorch to ONNX

PyTorch tutorial on exporting a simple model to ONNX
Exporting a Model from PyTorch to ONNX and Running it using ONNX Runtime

dummy_input = torch.randn(1, 3, 256, 256)
torch.onnx.export(network, dummy_input, MODEL_NAME+'.onnx' )

ONNX

python3 demo_onnx.py

You can try different execution ways, see onnx doc

TRT

trtexec --onnx=OV_enhance_color-llie-ResCBAM_g.onnx --saveEngine=CPGANet_engine.trt --explicitBatch --workspace=128
