Unable to generate single images after training with the notebook.

After training a model, the notebook is unable to generate image results. When the following command is run, the following error occurs-
!python generate.py --outdir=/content/out/images/ --trunc=0.8 --seeds=0 --network=/content/drive/MyDrive/ladiescrop-network-snapshot-012885.pkl

generate.py:59: SyntaxWarning: "is not" with a literal. Did you mean "!="?

I'm having the same problem. It seems like an issue with the opensimplex import

[daanrongen]

So the issue is within the interpolation logic to generate video outputs (interpolating from seed to seed). opensimplex is used in the OSN() class that is used to predict noise in a noiseloop. If you comment all these out (along with the if else logic from generate_images(), it works. But you'll only be able to use interpolation=linear in generate.py.
