training problem

[zgzhhxx]

Hello,I would like to ask how to solve this problem：
main_ginar.py:141: FutureWarning: Non-finite norm encountered in torch.nn.utils.clip_grad_norm_; continuing anyway. Note that the default behavior will change in a future release to error out if a non-finite total norm is encountered. At that point, setting error_if_nonfinite=false will be required to retain the old behavior.
nn.utils.clip_grad_norm_(my_net.parameters(), max_norm=max_norm)

thank you
