It seems to fail import astra but it has installed it.

It looks like libastra might be the 11.2 version - I have no idea why, but we want the cuda 11.8 version. Not sure if that's the issue though.
libastra: 2.1.0-cuda11.2hb8489e9_0 conda-forge

my local environent has:
libastra 2.1.0 cuda11.8hb8fb34d_111 conda-forge
