An setup 2

[ANaka]

finally got this running on my home machine, a couple little things

1. made a small change to install-deps.sh to get dune build to work. seems to stem from me having my username be naka rather than ubuntu. one thing I'm noticing is that I'm getting a new libtorch subdirectory in the repo... not clear to me why that's happening as I would expect it to be in my home directory (and indeed, there is one there). I just added it to .gitignore rather than getting too fussed about it
2. added some optional stuff to build a python virtual env

All looks great, but is there a reason for preferring pyenv vs the built-in python venv? I tried installing it, but pyenv local 3.10 returns pyenv: version3.10.0' not installed` (??)

Either way, seems we'll need a source script, since ocaml also needs the environment setup properly -- just added it via environment.sh

sorry for the late reply. pyenv is just for python installation + version management - so pyenv install 3.10 would work. I like using it with poetry because it lets you re-use python executables among virtual environments that share the same python version - so you end up installing fewer pythons than if you had a bunch of conda environments that all specify a python (I think). I think you can use pyenv in concert with poetry/venv/virtualenv/conda.

Like I said, I've been pretty up on the poetry + pyenv combo lately but one downside is that poetry is python specific, which is actually a big disadvantage here... it looks like ocaml can be installed by conda and maybe opam too... I'll take a crack at that and see if its feasible, IMO that's a pretty low overhead solution if this can all be wrapped up inside a conda env

[ANaka]

conda did a great job from what I can tell - it looks like it is possible to isolate opam and ocaml installs within that.

Yeah, I do like getting both languages in one environment! Testing it out, running into this:

clock_gettime not found ??? Realllly. I must have messed something up. Let me poke around more so we can merge this.

damn this actually happened to me too today... i'll see what I can figure out

[tlh24]

I'm not a huge fan of anaconda, so if you feel like going back to poetry, by all means...

(GCC 9.3 is already three years old, e.g.)
