cannot find the file "chosen_classes.txt" about refined

On the class_selection.py#L152 file, you can add a condition to check if the chosen_classes.txt.part exists. If not, then you can directly create the chosen_classes.txt and save the classes.

if os.path.exists(os.path.join(resources_dir, 'chosen_classes.txt.part')):
    os.rename(os.path.join(resources_dir, 'chosen_classes.txt.part'),
             os.path.join(resources_dir, 'chosen_classes.txt'))
else:
    with open(os.path.join(resources_dir, 'chosen_classes.txt'), 'w') as f_out:
        f_out.write('\n'.join([x for x in chosen_classes]))
return

Another solution might be to comment out this early exit condition and wait until it finishes all the pages. This would probably take forever so I wouldn't recommend it.
