D_loss becomes NAN during training #28

Closed zhouzg closed 4 years ago

zhouzg commented 4 years ago

Hi, I meet a problem during training：D_loss becomes NAN I have tried several times and the problem always appears at around 2600 steps. I have loaded the teacher ckpt and I only changed data-dir and batch-size(from 8 to 6 since limited by memory) in "run_train_val.sh" .

issue25 seems to meet a similar problem. But I can't find branch d1ec858 mentioned in that issue.

Could you please give me some advice? Thank you! and Best wishes!

git clone all the code, and then git checkout d1ec858 You will find that branch.
