ImportError: libffi.so.8: cannot open shared object file: No such file or directory

[jtlz2]

I am desperately trying to install sparse-dot-topn on amazonlinux but receive the error below.

I can't for the life of me figure out how to get libffi.so.8 onto that distro.

Any ideas / workarounds? Thanks!
