Hi, Please try this:
$ ldd /home/ubuntu/djangoproject/env/lib/python3.5/site-packages/i graph/_igraph*.so This should tell you which libraries _igraph.so is trying to link to; in my case, it includes a line like this: libxml2.so.2 => /usr/lib/x86_64-linux-gnu/libxml2.so.2 If you have a line like the one above, check the .so file that it refers to and verify that it exists and is not a dangling symlink.
