ValueError: axes don't match array, images will work one run and not work the next

I'm working on training a GAN through with a dataset of photos I scraped from Bing Image Search API and converted to 1024x1024, but keep getting this error when creating the tfrecords:

Traceback (most recent call last):
  File "dataset_tool.py", line 1249, in <module>
    execute_cmdline(sys.argv)
  File "dataset_tool.py", line 1244, in execute_cmdline
    func(**vars(args))
  File "dataset_tool.py", line 714, in create_from_images
    img = img.transpose([2, 0, 1]) # HWC => CHW
ValueError: axes don't match array

I then printed out what image files it would stuck on, and began taking those out of the dataset. But what it stalls on seems completely random. Anyone experienced similar issue?
