Hi, I am using the new 12.0 release of Mathematica.
I have Python 2.7 installed on my Mac and it is working fine (from shell). When I execute
FindExternalEvaluators[]
it correctly identifies my Python installation. However, when I execute
StartExternalSession["Python"]
it fails, with the message:
"StartExternalSession::noinstall: No valid installations for system Python were found with the options specified."
Then I tried this:
StartExternalSession[<|"System" -> "Python", "Version" -> "2.7.10",
"Executable" -> "/usr/bin/python"|>]
That too fails:
StartExternalSession::replFail: The process for external system Python (/usr/bin/python) failed to start due to : no input returned from process.
What could be the problem?
