Today I noticed Ultimaker Cura didn't start anymore. The lowest level error was:
ImportError: /usr/lib/python3.10/site-packages/scipy/spatial/_distance_wrap.cpython-310-x86_64-linux-gnu.so.avx2: undefined symbol: npy_copysign
By my limited understanding and research this seems to be a version incompatibility. I went on this site: https://anaconda.org/scipy-wheels-nightly/scipy/files# and downloaded this nightly build file: scipy-1.10.0.dev0+1575.dc45894-cp310-cp310-manylinux_2_17_x86_64.manylinux2014_x86_64.whl and installed it manually with
pip3 install scipy-1.10.0.dev0+1575.dc45894-cp310-cp310-manylinux_2_17_x86_64.manylinux2014_x86_64.whl, which made Cura working again.
Don't know about side effects. And I don't know how to replace the nightly build with the stable version from the repos later, yet....
