Problem

After installing the LSF python API, sometimes the python API still cannot work with LSF: $ python Python 3.6.1 (default, May 11 2017, 19:56:03) [GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on linux Type "help", "copyright", "credits" or "license" for m11ore information. >>> from pythonlsf import lsf Traceback (most recent call last): File "", line 1, in File "/proj/mtk02966/python_3.6.1/lib/python3.6/site-packages/pythonlsf/lsf.py", line 25, in _lsf = swig_import_helper() File "/proj/mtk02966/python_3.6.1/lib/python3.6/site-packages/pythonlsf/lsf.py", line 21, in swig_import_helper _mod = imp.load_module('_lsf', fp, pathname, description) File "/proj/mtk02966/python_3.6.1/lib/python3.6/imp.py", line 242, in load_module return load_dynamic(name, filename, file) File "/proj/mtk02966/python_3.6.1/lib/python3.6/imp.py", line 342, in load_dynamic return _load(spec) ImportError: /proj/mtk02966/python_3.6.1/lib/python3.6/site-packages/pythonlsf/_lsf.cpython-36m-x86_64-linux-gnu.so: undefined symbol: PyCObject_FromVoidPtr >>> Here, another issue is that "undefined symbol: PyCObject_FromVoidPtr". It is not an LSF issue, but an issue of CObject. Technically, this issue might happen because the version of SWIG is too old. This could be handled by upgrading the SWIG.
