Is there a way to get `t_prev`, so that I know how far I should be backtracking?

Also is there a way to get the parameters of the interpolant? That will be necessary to do this in closed-form.

The comment [here](url) suggests that `vendor()` has been removed since multiple vendors can be loaded simultaneously. Furthermore the `vendor()` function only ever returns `:openblas` or `:openblas64`, so I think the...

Update this is reproducible even after deleting `~/.julia/conda`

I get ``` [nix-shell:~/dev/research/julia/permuted_sgd]$ python3 -c "import distutils.sysconfig; print(distutils.sysconfig.get_config_var('VERSION'))" 3.9 ``` I think the weird thing is that it's trying to run the wrong python3: `/nix/store/nki9ywqzbvz68vr75kn2r7g1q84f5agy-python3-3.9.6/bin/python3` whereas what's installed is...

FWIW part of the magic of nix-shell is that I'm freed from having a global python install across the whole system. That may be part of what's tripping it up.

I did a little more poking around and I think I better understand the issue now. The problem is that part of PyCall's `] build` process involves the generation of...
