Hi,

I was trying to load the pretrained OpenAIDiscreteVAE in Colab and for some reason I keep getting this error about it not being found. Does anyone know why this happens?

Code ran in Colab:

!pip install git+https://github.com/lucidrains/DALLE-pytorch.git

from dalle_pytorch import OpenAIDiscreteVAE
vae = OpenAIDiscreteVAE()

Error message:

/usr/local/lib/python3.7/dist-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.26.4) or chardet (3.0.4) doesn't match a supported version!
