GANLearner Error No Implementation Found on types that implement InvisibleTensor

fastai

I’m also trying to run a simple GANs notebook in google colab.

Running

!pip install "fastcore==1.3.2"
!pip install "fastai>2,<2.1"

solves the InvisibleTensor problem for me, but then the GPU is no longer available.

I tried combining it with the light-the-torch solution shown here by running:

!pip install light-the-torch >> /.tmp
!ltt install torch torchvision >> /.tmp
!pip install "fastcore==1.3.2" >> /.tmp
!pip install "fastai>2,<2.1" >> /.tmp

but the GPU is still unavailable.

Should I just not downgrade, and try casting to TensorBase? Also, how to go about that because just casting to TensorBase instead of to InvisibleTensor seems to fail as well.
