❓ Questions and Help

I've successfully installed baspacho. However, I got the following error when I try import theseus.extlib.baspacho_solver. Do you know how to solve this issue?

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: /home/stsui/theseus/theseus/extlib/baspacho_solver.cpython-310-x86_64-linux-gnu.so: undefined symbol: dsyrk_

Hi @shengtsui. I'm not familiar with this error. Are you able to use our Baspacho solver if you install with pip install theseus-ai?

I found out a solution by preloading MKL package.
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libmkl_def.so:/usr/lib/x86_64-linux-gnu/libmkl_avx2.so:/usr/lib/x86_64-linux-gnu/libmkl_core.so:/usr/lib/x86_64-linux-gnu/libmkl_intel_lp64.so:/usr/lib/x86_64-linux-gnu/libmkl_intel_thread.so:/usr/lib/x86_64-linux-gnu/libiomp5.so
