Note: README.md said to do sudo python setup.py install but I did this without sudo as I don't have sudo access to the system.

Environment

$ python --version
Python 3.7.10
$ cython --version
Cython version 0.29.33
$ uname -r
4.14.246-187.474.amzn2.x86_64

This issue can be fixed by installing system package python3-devel, but I don't know any way to do that without sudo access.

@aaiyer Maybe the error message of setup.py install can mention that the system package python3-devel needs to be installed first.
