Since the author did not shows how to export the pytorch model to onnx. I write a script to do it.
You can launch the script by running:
python tools/export_onnx.py --cfg experiments/coco/hrnet/w32_256x192_adam_lr1e-3.yaml TEST.MODEL_FILE models/pytorch/pose_coco/pose_hrnet_w32_256x192.pth**
I have not try to inference with this onnx file. I would appreciate it a lot if someone can provide the script to inference with onnx file. Thanks!
