Zero-sized dimensions are not supported in PyTorch

Is there anyone got this problem ? how should I solve this

I have encountered the same problem and I guess it's because your annotation or other stuff are empty. The pytorch can't handle e.g. 01010 tensor while numpy.ndarray does.

I found the in the datasets/pascal_voc.py has bugs, if your annotation has ymin or xmin is 0, the loaded annotation would be 65535 which is out of range of width and height, make sure the loaded data to be positive! From my experiment, modified the datasets/pascal_voc.py line near line ~220 change the code by this.

x1 = max(float(bbox.find('xmin').text) - 1, 0)
y1 = max(float(bbox.find('ymin').text) - 1, 0)
x2 = max(float(bbox.find('xmax').text) - 1, 0)
y2 = max(float(bbox.find('ymax').text) - 1, 0)

which solved this issue. 👍
