glob on Windows

[mindtd]

When running on Windows, the '/' will result in error, int() problem with string.

Workaround is to change '/' to double backslash '\\', specifically:

1. def get_class(img_path):
   return int(img_path.split('\\')[-2])

2. root_dir = 'GTSRB_Final_Training_Images\\GTSRB\\Final_Training\\Images\\'

3. all_img_paths = glob.glob(os.path.join(root_dir, '* \\ *.ppm'))

That fixed the int() error.

Coding solution will be:

1. def get_class(img_path):
   return int(img_path.split(os.sep)[-2])

2. as is, non issue.

3. all_img_paths = glob.glob(os.path.join(root_dir, os.path.join(' * ', ' *.ppm')))

Thanks.
