I tried to see if there is any alternative to pyexpat.*.so but it seems there is none did ldd on the last line below is the out put

I did a search for libexpat.so.1

[root@whf00jkd python3.6]# ls -ltr /usr/lib/libexpat.so.1

[root@whf00jkd python3.6]# ls -ltr /usr/lib64/libexpat.so.1
lrwxrwxrwx. 1 root root 17 Apr 1 2019 /usr/lib64/libexpat.so.1 -> libexpat.so.1.6.0
and added a link libexpat.so.1 -> /usr/lib/libexpat.so.1 in /usr/lib64/python3.6/lib-dynload/ but that is not removing the error
Please help
libexpat.so.1 pointing to wrong location. Fixed it with
