I am going to call Wolfram Language functionality from Python. The online documentation for this, at Python Client give the “evaluation” version. Since I have a Mathematica license, I would like to use the regular version rather than the evaluation version.
The path given in the web page does not correspond to what I have on my Linux computer.
I haven’t tried it yet myself, but browsing the code for the Python library it looks like you can specify your own installation location via the environment variable WOLFRAM_INSTALLATION_DIRECTORY .
That gets checked before the library attempts to find the engine in the the default locations. You can see the code that looks for the kernel in the file evaluation/kernel/path.py.
