Reproducible example

$ curl -fsSL https://pixi.sh/install.sh | bash
$ pixi init pixi-rapids-test --channel rapidsai --channel conda-forge --channel nvidia
$ cd pixi-rapids-test
$ export RUST_BACKTRACE=full  # to get better error for GitHub issue
$ pixi add rapids==23.08 python==3.10 cudatoolkit==11.8 ipython

Issue description

Thought I would have a quick go at installing RAPIDS using pixi and attempted to port these conda instructions to pixi. However, when I try and add the packages I get a rust panic.

Expected behavior

I would expect the packages to be added and then my goal was to try and run

$ pixi run ipython

Thanks for the report! The issue was caused by the use of local versions (e.g. ...+<version>) which wasn't expected in the repodata.

I fixed this issue in rattler: conda/rattler#281

Will be available with the next release most likely.

Thanks @jacobtomlinson for reporting! One more edge-case gone thanks to community testing :)

Thanks for the crazy fast turnaround!
