Docker build errors on Mac (w/ARM chip)

[derifatives]

I installed docker and tried running docker build -t gen:v0 . It boils for awhile and then fails with a ton of errors while trying to build matplotlib. There's too much to cut and paste the whole thing but the first error seems to be:

#10 3.414     ERROR: Command errored out with exit status 1:
