Fastai v1 install issues thread

having problems to install fastai on my shiny Raspberry Pi 4 with 4GB, Raspbian Buster OS

I have spent 2 days on getting things e.g. PyTorch, imgaug etc. running on my Pi and finally I made my way to touch Fast.Ai, but sadly, it failed at installing fast.ai.

I followed this post to install Fast.Ai on Pi

After installed all dependencies successfully, I started installing fastai:

sudo pip3 install fastai --upgrade > /dev/null

here is the error:

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-i0byv1vc/spacy/

Please help, I think this is the last barrier to get Fast.Ai on my Pi~!

Thanks
