How to run convert_bin_to_hdf5.py ?

[JANGSOONMYUN]

Hi, I've finished the pre-processing but there was an error occur after running "python utils/convert_bin_to_hdf5.py"

Traceback (most recent call last):
File "utils/convert_bin_to_hdf5.py", line 66, in
convert_num_to_bitfield(label_data, h, w, npz_name, root_folder, h5_file)
File "utils/convert_bin_to_hdf5.py", line 30, in convert_num_to_bitfield
padded_bit_tensor = torch.cat((torch.zeros(cls_num-actual_len).byte(), bit_tensor.byte()), dim=0)
RuntimeError: $ Torch: invalid memory size -- maybe an overflow? at ..\aten\src\TH\THGeneral.cpp:188

The main reason of the error is that 'cls_num' is smaller than 'actual_len', so 'cls_num-actual'_len value is under 0.

I don't understand what is 'actual_len'. What does the actual length mean?
