FileNotFoundError & Use of Checkpoints

[Towel2000]

Hi, I tested out this work and ran it with 1 GPU and at batchsize of 2.
When it was about to finish step2:

E0000/T01393/step2/ 1.4Hz loss: 1.11773 E0000/T01394/step2/ 1.5Hz loss: 1.12929 E0000/T01395/step2/ 1.4Hz loss: 1.13798 E0000/T01396/step2/ 1.4Hz loss: 1.15100 E0000/T01397/step2/ 1.4Hz loss: 1.15270 E0000/T01398/step2/ 1.5Hz loss: 1.13861 E0000/T01399/step2/ 1.4Hz loss: 1.15327

and ended up with this error:

FileNotFoundError: [Errno 2] No such file or directory: 'results/car/images/car\\000000/car\\000000_normal_rotate_stage0_000.png'
It was weird for it to locate an image since it shouldn't have already generated image in the file.
Also, how do I make use of the checkpoints.pth generated half way?

Thank you.
