No.
It's not clear what you've done here - have you tried to create an
executable or a module? If you've created an executable then you need to
point it to the Python path (i.e. where it can find requests). Use
PySys_SetPath or similar
(https://docs.python.org/3.8/c-api/sys.html#c.PySys_SetPath)
If you're just looking to create a self-contained executable then there are dedicated tools that are much more suitable than Cython, like PyInstaller, cx_freeze, nuitka.
