Unable to install fastai on Jupyter Notebook

Question

I'm currently trying to get fastai installed on a conda environment using the command conda install -c fastai fastai as shown in the installation guide. This is what appears when that command is ran:

(fastai) C:\>conda install -v -c fastai fastai
Collecting package metadata (current_repodata.json): ...working... Unable to retrieve repodata (response: 404) for https://conda.anaconda.org/fastai/win-64/current_repodata.json

I can't say I completely understand what the issue is here. I previously thought it was an issue with PyTorch but after installing PyTorch successfully, I am still greeted with this message. Any ideas on how I can this package installed on my environment? Any help is appreciated. Thank you!

Try downgrading from python3.8 to python 3.7, it works for me.
