AttributeError: 'memoryview' object has no attribute 'size'

When I run train.py python train.py --datacfg cfg/ape.data --modelcfg cfg/yolo-pose.cfg --initweightfile backup/ape/init.weights

i got this error AttributeError: 'memoryview' object has no attribute 'size'

For you or anyone else getting a similar error and curious: this happened to me and the reason was that I was calling foo.data.size() on an object foo that was expected to be a PyTorch Tensor, but was actually a NumPy Array (the .data attribute of a numpy array apparently returns a memoryview object).

I wasn't using this library at all, but the advice is generic enough that it might still be useful to anyone searching for this error message
