Setting up fast_align

I followed the steps mention to setup fast align in my system. However, i am facing some difficulties.
Can anyone tell me exact procedure?
Do I have to train first and then calculate alignment on my test data?
Any python based approach?

No file, test, or entry point is named; start by reviewing the setup steps referenced in the issue and the repository description. Done means documenting the exact setup and usage procedure, clarifying whether separate training is needed for test data, and addressing the request for a Python-based approach without leaving these questions open.
