Hey, congrats on the paper, I read it a while ago and thought it was really interesting.

I tried implementing it, and the samples generated by the Teacher seem to suffer from mode collapse (as if the generator is ignoring the random vector z but not the label condition). Do you recall having that issue at some point?

I have to say I'm using a simpler generator than the one in the paper, and I'm not changing the learner architechture at each batch, only its weights.

Thanks!

Thanks, I'm glad you liked it! Mode collapse was actually the one thing I never encountered during my exploration (which was the reason we looked into using GTNs as a mode-collapse solution for GANs). That said, I found meta-learning to be surprisingly hard to implement efficiently and ran into more bugs in both PyTorch and TensorFlow than I can count.

Changing the learner architecture is not that important actually so that's probably not your problem.

Ok, I'll keep digging to figure out where the problem might be, thanks!
