[spam] [personal] perceiver model notes

[k]

this perceiver_play.py actually starts training:
https://ipfs.io/ipfs/bafkreibseocnytskgmuyfelgsoeyipvg44w3rcnhhxmvkkhvur3o33e56y

note: you can upload things to ipfs without running a daemon using
`npm install -g nftp` and signing in https://nft.storage/

crashes my rasbpi torch (need to rebuild torch or patch more
operations in mempickle).  also crashed colab somehow, maybe a strange
coincidence.  hope to test something like it eventually.  the training
of the pyc2py model in the other thread is halted for now, because
colab won't let me connect right now.
