ImportError with libcblas on macOS #1163

When attempting to import the pyccl library after installation, I encounter the following ImportError related to the libcblas library not being loaded:

import pyccl

File ~/anaconda3/lib/python3.11/site-packages/pyccl/init.py:22 from . import ccllib as lib

File ~/anaconda3/lib/python3.11/site-packages/pyccl/ccllib.py:16 from . import _ccllib

ImportError: dlopen(/Users/qijingzhao/anaconda3/lib/python3.11/site-packages/pyccl/_ccllib.so, 0x0002): Library not loaded: @rpath/libcblas.3.dylib Referenced from: <85EFA90A-BE88-35A7-AD9E-F20432CD4AFA> /Users/qijingzhao/anaconda3/lib/libgsl.25.dylib Reason: tried: '/Users/qijingzhao/anaconda3/lib/libcblas.3.dylib' (no such file), '/Users/qijingzhao/anaconda3/lib/python3.11/site-packages/pyccl/../../../libcblas.3.dylib' (no such file), '/Users/qijingzhao/anaconda3/lib/python3.11/site-packages/pyccl/../../../libcblas.3.dylib' (no such file), '/Users/qijingzhao/anaconda3/bin/../lib/libcblas.3.dylib' (no such file), '/Users/qijingzhao/anaconda3/bin/../lib/libcblas.3.dylib' (no such file), '/usr/local/lib/libcblas.3.dylib' (no such file), '/usr/lib/libcblas.3.dylib' (no such file, not in dyld cache)

I would greatly appreciate any guidance on resolving this issue.

Looks like some dependency is missing, maybe try to install conda install conda-forge::libcblas.

Thank you for your reply, but it's still not working.

Installing cmake and swig might solve this problem pip install swig

Thank you for your reply. Unfortunately I'm still getting the same error.

We did have some success with this same issue by first installing libcblas (conda install -c conda-forge libcblas) and then installing pyccl (conda install -c conda-forge pyccl). It may be worth ensuring pyccl is completely uninstalled before trying though...
