problem about test

[wwHwo]

hi， i got the pre-trained weight and try to run test_model.py, but i got the warning:
2022-08-07 21:11:11.538021: E tensorflow/core/grappler/optimizers/dependency_optimizer.cc:666] Iteration = 0, topological sort failed with message: The graph couldn't be sorted in topological order.

I can still get PSNR and SSIM, but it's quite unsatisfactory， do you have the same problem?
Looking forward your reply
