I successfully installed SeismicMesh by .whl , but when importing SeismicMesh in spyder, the following problems occur：

[autoreload of SeismicMesh.decomp failed: Traceback (most recent call last):

Can you confirm that you've installed a version of cgal >= 5.0?

Older versions of pip may hide the installation error.

Yes，I have installed the package named cgal 5.5.1.post202210191030 by pip.
Do I need to reinstall it by other ways?

The error occurs because the CPP modules did not compile correctly. Please use python setup.py develop in the package directory and see what the error is.
