@arilotter:matrix.orgAri Lotteris there a more general python/ml Nix chat anywhere? trying to get some stuff that isn't technically cuda-related going21:24:26
@glepage:matrix.orgGaétan Lepage Just ask it here. There is no other "python+ML" official room I'm aware of.
The closest would be the official Python room, but you would end up pinging even more people.

yeah fair enough.

trying to depend on the python module outlines, it seems not to build because it has a hard requirement of outlines-core==0.2.11, but the version of -core in nixpkgs is 0.2.13. seems like latest outlines release still does depend on 0.2.11. wondering if it makes more sense to PR to.. revert the core update? because it seems like outlines must have been "broken" since https://github.com/NixOS/nixpkgs/commit/a5370c8752db2465791097660563b3b2441b56ac
either that or something changed about the pythonRuntimeDepsCheck - the error i get is that f"{package_name}{requirement.specifier} not satisfied by version {package.version}"

@glepage:matrix.orgGaétan Lepage Yes, I already fixed it in https://github.com/NixOS/nixpkgs/pull/476381.
You can track it here: https://nixpkgs-tracker.ocfox.me/?pr=476381

RE onnxruntime-dependent segfaults when cudaSupport is enabled.

Apparently, this does not only happen in onnxscript, but also in rapidocr-onnxruntime.

@glepage:matrix.orgGaétan Lepage Addressed in https://github.com/NixOS/nixpkgs/pull/478028. 10:46:28
