Cycle_A loss suddenly becomes very high #1599

Open JunCS1 opened 1 year ago

JunCS1 commented 1 year ago

Hi, @junyanz @taesungp

does anyone encounter issues like the cycle_A loss suddenly becomes very high after a random iteration? my loss log shows that in epoch 78, the discrimintor loss suddenly decrease to close to zero and my generator loss goes from 0.2ish to almost 1 and 2. The cycle_A loss also looks like being suddenly very high.

The inferenced image is all black now after these severeal losses exploded.
