When installing lycon through pip using a pre-built wheel build on an AMD EPYC 7282 the installation fails to load with illegal instruction.

The solution to get around this was to install through pip with the following command:

pip install --no-binary=lycon lycon

This might hint at a problem with the pre-built binaries being optimized to specific to the build farm CPUs?
