Hi,
I'm trying to write a Go executable that is able to pick up whichever Python version (hence libraries) it's running on. For example, in macOS the default system Python is 2.7.14, but could be executed within Python 3.6.5 virtualenv. As you know, working with virtualenv it's quite nice too, because the libraries installed within the env won't have to be globally installed.

I have tried to prefix the PYTHON_HOME env variable with the VIRTUAL_ENV (Python bin) before python.Initialize(). However this seems to result in still picking the system Python 2.7.14. I can see the PATH env variable started with the correct VIRTUAL_ENV path, but the embedded Python once again is still picking up the system Python.

One of the suggested workarounds on StackOverflow: 7492855 with (Python C API) was to set the program name via Py_SetProgramName. Although I don't seem to be able to find this function on go-python.

Anything suggestions ? or, perhaps I'm missing something quite obvious.

Thanks and regards,
Wan.
