Description
Hello guys,
We got an error thrown by polars and it suggested to install polars-lts-cpu instead while using wetterdienst. Specifically, wetterdienst currently installs polars by default, which causes errors in our environment:
/usr/local/lib/python3.10/site-packages/polars/_cpu_check.py:258: RuntimeWarning:
Missing required CPU features.
The following required CPU features were not detected:
avx2, fma, bmi1, bmi2, lzcnt, movbe
Continuing to use this version of Polars on this processor will likely result in a crash.
Install the `polars-lts-cpu` package instead of `polars` to run Polars with better compatibility.
Hint: If you are on an Apple ARM machine (e.g. M1) this is likely due to running Python under Rosetta.
It is recommended to install a native version of Python that does not run under Rosetta x86-64 emulation.
If you believe this warning to be a false positive, you can set the `POLARS_SKIP_CPU_CHECK` environment variable to bypass this check.
DAMN ! worker 2 (pid: 12) died, killed by signal 4 :( trying respawn ...
Respawned uWSGI worker 2 (new pid: 62)

The error suggests using the polars-lts-cpu package instead, which is more compatible with our system's CPU features. However, even when polars-lts-cpu is already installed, installing wetterdienst automatically installs polars, which leads to errors.
Here are the behaviors we observed:
- Installing
polars==0.20.25withwetterdienst==0.97.0results inpolarsbeing correctly set to version 0.20.25. - However, installing
polars-lts-cpu==0.20.25withwetterdienst==0.97.0results in bothpolars==1.20.0andpolars-lts-cpu==0.20.25being installed, which causes conflicts. To resolve this, we have to manually uninstallpolars.
Suggested Solution
Would it be possible to adjust the package’s dependencies to support both versions? For example:
- During the installation or initialization process,
wetterdienstcould check if eitherpolarsorpolars-lts-cpuis already installed. If one of these packages is detected, it would skip the automatic installation ofpolars.
We believe this change would make your package more flexible for users with different compatibility needs. Thank you for your time and consideration!
