Undefined symbol

[cgstathis]

I followed the instructions in the README to install and the import statement fails inside the conda env.

ImportError: /home/stathis/.local/lib/python3.10/site-packages/nksr/_C.so: undefined symbol: _ZN2at4_ops11linalg_norm4callERKNS_6TensorERKN3c108optionalINS5_6ScalarEEENS5_16OptionalArrayRefIlEEbNS6_INS5_10ScalarTypeEEE

Same problem here. Did you find a solution ? I could actually import just after install, and then I ran into this linking error. Seems like having two libraries in the system and linking against the wrong one.

@cedricpradalier nope

I ended up restarting my venv with new conda environment solver (https://stackoverflow.com/a/77090765) and the error disappeared. I could test NKSR on my data and I haven't found any way to get a decent result so far, but at least it runs.

I have the same problem, I tried to change the solver as suggested by @cedricpradalier but it didnt work for me. Are there any other suggestions?

Thank you very much.
