GEOS version warning

[mh0797]

I get the following when running a training or simulation

warnings.warn(pid=318140) /home/aah1si/.conda/envs/nuplan/lib/python3.9/site-packages/geopandas/_compat.py:111: UserWarning: The Shapely GEOS version (3.10.2-CAPI-1.16.0) is incompatible with the GEOS version PyGEOS was compiled with (3.10.1-CAPI-1.16.0). Conversions between both will be slow

The requirements.txt does not fix a version for geopandas and Shapely.

I managed to get around this warning after applying these steps:

1. Reinstall shapely: pip install --force-reinstall --no-binary shapely shapely. Originally stated here.
2. If encounter OSError: /home/users/xxx/miniconda3/envs/nuplan/lib/libgeos_c.so: cannot open shared object file: No such file or directory, then do conda install -c conda-forge pygeos to fix the missing library problem.
3. export LD_LIBRARY_PATH=$LD_LIBARRY_PATH:$HOME/miniconda3/env/nuplan/lib to include lib search path.

Those should fix the warning.

I also had a problem of OSError: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /home/users/xxx/miniconda3/envs/nuplan/lib/libgeos_c.so) which was fixed by installing gcc-6 using conda.

Hi @JingyuQian! Thanks for sharing your solution. We are aware of it, we are just trying to make the installation as seamless as possible. We should have an update soon!

[mh0797]

Hi @gianmarco-motional. is there an update on this ? The issue still persists with the version 0.3 of the devkit.

Yes, we are aware of this. Unfortunately, there is no clean way to bake this into the installation instructions. We are looking to silence the warning in run_training.py and run_simulation.py. This will be a part of the v0.4 update coming put soon

Hey @mh0797, this should be resolved on current master now for the most common workflows. In case you see the error again, the next release should fully squash it.
