Get the path to the Python executable that reticulate has been configured
to use. If Python has already been initialized, then reticulate will
choose the currently-active copy of Python.
py_exe()The path to the Python executable reticulate has been configured
to use.
This can occasionally be useful if you'd like to interact with Python (or its
modules) via a subprocess; for example you might choose to install a package
with pip:
system2(py_exe(), c("-m", "pip", "install", "numpy"))
and so you can also have greater control over how these modules are invoked.
