"AttributeError: 'collections.OrderedDict' object has no attribute 'state_dict" about pytorch-ssd

"torch.save(net,'mb_v1_ssd_all.pth')" should be "torch.save(net.state_dict(),'mb_v1_ssd_all.pth')". Otherwise, I couldn't see where the problem is either.

hi, thank you for reply,
I've tried "torch.save(net.state_dict(),'mb_v1_ssd_all.pth')" , it do can save pth file ,but when i use mmdnn to convert the torch net（using the saved pth）, an error occurs: "AttributeError: 'collections.OrderedDict' object has no attribute 'state_dict'" .
The reason is : the whole net (including both architecture and weights) is needed using mmdnn.
please kindly refer to the FAQ of mmdnn's pytorch instruction :
https://github.com/Microsoft/MMdnn/blob/master/mmdnn/conversion/pytorch/README.md#faq
So the point maybe is : how to save the whole net ?
would you please give me some idea?
