Error during large scale training

[Kavit212]

Hello, thank you very much for sharing your codes.

When during large-scale training, I came across this error. Can you kindly let me know where I went wrong.
The error code is below.

========== Reading Checkpoints ============
============= Failed to find a checkpoint =============
