An alternative interpreter for python with JIT compilation
You can run your pure python files, but instead of python interpreter, you run pypy interpreter.

Today I found out that the usual python command we are used to run on any machine, is in reality the CPython interpreter. CPython is the “reference” and default and mostly-used, but its not the only interpreter in python ecosystem.

Performance of pure python with pypy significantly faster.

But some modules like Numpy, Scipy call CPython C API extensions, where pypy may cry to run the python code, because those C APIs are not meant to be run on a different interpreter like pypy.

Best way to know about these things is read their FAQ

Install pypy using their official website, as newer versions support python 3.10.

Conda-forge has older builds, and they recently dropped support for pypy train because of maintainence overhead.
