Batch-size Error

[Royalbx]

I get the error, and don't know how to solve it.
python -m pytorch_fid D:/Code/dcgan/dataset/cargo D:/Code/PyTorch-GAN/implementations/wgan_gp/cargo_generat2

Have you solved it please, I'm getting the same error

[Howard-Lee-666]

same problem

[yhcha96]

Me either. Is there anybody who solved the problem?

[xiaoxiaodadada]

It's just that the path to the image is written incorrectly and the folder where the image is guaranteed to be read.
If it doesn't work, convert it to .npz format and try reading it again!

I had this error for two reasons. Firstly, ensure that the file extension is one of the following:

IMAGE_EXTENSIONS = {'bmp', 'jpg', 'jpeg', 'pgm', 'png', 'ppm','tif', 'tiff', 'webp'}

It must also be lowercase (My .JPEG files were not being read).

Secondly, it does not search subdirectories, which is annoying if you have train and test sets, subclasses, etc. However, if you dive into the source code and change one letter on line 242 from

for file in path.glob('*.{}'.format(ext))])

to

for file in path.rglob('*.{}'.format(ext))])

This should search the directory recursively.
