Yes, I did so by :
torch.save(net,‘mb_v1_ssd_all.pth’)
but it seems can not save the  mb_v1_ssd_all.pth file with error information:
File “/home/hong/anaconda3/envs/PyTorch1.0_GPU_ONNX/lib/python3.7/site-packages/torch/serialization.py”, line 291, in _save
pickler.dump(obj)
TypeError: can’t pickle module objects
I’m puzzled …
