No errors, but output images are blank/white

[jluyt123]

I do not get any errors as such

For WITH SCRATCHES -- If I run the following, the script completed but all I get is 5 empty images, white, all of them:
python3 run.py --input_folder /mnt/d/ir/test_images/old_w_scratch/ --output_folder /mnt/d/ir/imgs-out/ --GPU 0 --with_scratch

NO SCRATCHES:
If I run the test images without scratches
python3 run.py --input_folder /mnt/d/ir/test_images/old/ --output_folder /mnt/d/ir/imgs-out/ --GPU 0

It completes but only 4 out of 8 was processed, the other 4 for blank/white.

This is all using the test images, nothing funny. Any help?
