cannot find module after installation

[mwas01]

I installed the package as per instructions but I'm getting following error (trying to run one of the examples provided in the repo):

LSF: 10.1.0.8
Python: 3.9.5

`hostname[~/repo/lsf-python-api/examples][master !?]$ python3 cluster_info.py
Traceback (most recent call last):
File "/home/myuser/repo/lsf-python-api/examples/pythonlsf/lsf.py", line 18, in swig_import_helper
fp, pathname, description = imp.find_module('_lsf', [dirname(file)])
File "/app/vbuild/RHEL7-x86_64/python/3.9.5/lib/python3.9/imp.py", line 296, in find_module
raise ImportError(_ERR_MSG.format(name), name=name)
ImportError: No module named '_lsf'

During handling of the above exception, another exception occurred:
