Question about make_h5.py

[Jupiter-hzh]

tostring( ) is not supported in Python > 3.6, so I use tobytes( ) instead, but it looks like something wrong happened in frame. It has NULL so it can't work. Can you help me?

Hi @Jupiter-hzh, as described in the h5py documentation, the data parameter in create_dataset should be a NumPy array. Therefore, I fixed this error by converting tmp_frames, which is a list, to a NumPy array before passing it to create_dataset. In any case, I would like to hear from the authors if this is the correct way to handle the problem.

The target of using h5py is just reducing the indexing time in training stage. If you want to test it only, you can rewrite the datasets.py to read videos directly.

Thanks. For anyone has the same error, here is the snipet:

            tmp_frames = np.asarray(tmp_frames)
            h.create_dataset(key,data=tmp_frames,chunks=True)

I have updated the codes of this part, thanks @chuong98 @luca-zanella-dvl
