Adafactor from transformers hugging face only works with Transfromers - does it not work with Resnets and MAML with higher?

580 Views Asked by At

To reproduce

I am running the MAML (with higher) meta-learning algorithm with a resnet. I see this gives issues in my script (error message pasted bellow). Is Adafactor not suppose to work with Resnets or other models?

Steps to reproduce the behavior:

  1. run this code: https://github.com/brando90/higher/blob/master/examples/maml-omniglot.py (it already has adafactor)
  2. if that works uncomment the resnet12 line and ping me please

Expected behavior

I expect training to go smoothly but isntead get:
