My question is similar to the one posted here: WolframEngine install + wolframclient for Python on Ubuntu. However, this solution is not fixing my problem.

I cannot get the wolframclient library to successfully connect to the WolframKernel that is installed on my machine.

I have installed Mathematica 12.0 (for student) on laptop (Pixelbook).

When I run:

from wolframclient.evaluation import WolframLanguageSession
session = WolframLanguageSession(kernel='/usr/local/Wolfram/WolframEngine/12.0/Executables/wolfram')
session.start() <-- this call will fail resulting in a socket exception: Socket operation aborted. 

we 'Failed to communicate with kernel'

Furthermore, I am able to launch Mathematica from terminal, so there is clearly an activated kernel.

Any thoughts?

  • $\begingroup$ The WolframEngine uses ZMQ sockets for communication beyond that, I don't know. The Kernels live in /usr/local/path-to-kernel so I don't think there would be a permissions problem. $\endgroup$

1 Answer 1


Note: One way I got around this was my instead pointing to my kernel that Mathematica uses.


However, this only works because my university has a site license for Mathematica. Therefore, this is not a true solution.
