how are you?

solved with tf reinstalation!

What is your tf version?

I have tried it with 1.12, 1.4.0 and 1.5.0. But cannot solve the issue. Any comment?

In this case it looks like there's no checkpoint saved yet. Make sure there is a checkpoint saved.

@daniel-kukiela where do i save the checkpoint file? Is it a .ckpt like a .txt file. I have the same issue. Need help. Kind regards.
