Python Application Crash with Error "Importerror: Pyexpat.X86_64-Linux-Gnu.So: Undefined Symbol: Xml_Sethashsalt"

pip3 throws undefined symbol: XML_SetHashSalt

libexpat.so.1 pointing to wrong location. Fixed it with

export LD_LIBRARY_PATH=/lib64/:${LD_LIBRARY_PATH}

ldd /usr/lib64/python3.6/lib-dynload/pyexpat.cpython-36m-x86_64-linux-gnu.so

Matlab-Python compiler SDK fails with undefined symbol: XML_SetHashSalt

I'm having the same issue. Solved:

cd /full_path_to_matlab_mcrroot/v94/bin/glnxa64
mv libexpat.so.1 libexpat.so.1.NOFIND

Thanks to https://bbs.archlinux.org/viewtopic.php?pid=1112017#p1112017

• Explanation:

/full_path_to_matlab_mcrroot/v94/bin/glnxa64/libexpat.so.1 pointed to libexpat.so.1.5.0

but

/lib/x86_64-linux-gnu/libexpat.so.1 pointed to libexpat.so.1.6.0
