Hey folks! My dependency generation is hanging when I try and use a nightly release of PyTorch. I have a downloaded whl inside a local directory. Things work fine with 1.12.0 which is the latest stable release. But when I try and install the nightly (

1.13.0.dev20220723+cu116

) my

generate-lockfiles

just hangs, it’s been going 1700s now. Is this some kind of parsing thing?

Huge thread, but maybe this: https://pantsbuild.slack.com/archives/C046T6T9U/p1658430551461569?thread_ts=1657840841.652759&cid=C046T6T9U If so, fixed here: https://github.com/pantsbuild/pex/pull/1858 with Pants fix here: https://github.com/pantsbuild/pants/pull/16285

Oh interesting, that could be it. If I understand correctly this is because of somewhat uncommon metadata in the

whl

itself. Is there some way I can modify the

whl

to make it compatible with the older Pants release?

You can always try upgrading Pex, it has a very stable interface that permits that. An example is here: https://github.com/lablup/backend.ai/pull/545/files#diff-0e52f2670837f305c9a0d8be0f90156bf366431563506c21584fa2ea4f42ba1fR50-R59 Just follow Joongi's example but for Pex 2.1.100.

mmm okay maybe I’ll wait for the new Pex to land and then upgrade it, until then I can try reverting PyTorch to 1.11.0 to fix the bug they introduced in 1.12.0 🙂
