Not working with Wolfram Language 11.3 on Linux (Debian, CentOS) #1

Closed Ludwiggle closed 5 years ago

Ludwiggle commented 5 years ago

Is it tested on LInux? I tried on Debian 9 and the installation does not give me errors, indeed I can create a new jupyter notebook with the Wolfram Langue 11.3 and the kernel starts but I cannot evaluate any expression; the terminal where I start jupyter tells me " Timeout waiting for kernel_info reply from" . Thanks

It has been tested on Linux, but it's possible there are still issues for some distributions. We will take a look at that combination of Debian and 11.3 to see if we can fix the issue.

I see the same problem with Mathematica 11.3 on CentOS 7:

version 12 is working on Linux:

Ok now it "works", but what if you write two expressions in a cell like 2+2 3+3

? That does not return anything

arnoudbuzing commented 5 years ago

This can be closed now?

Ludwiggle commented 5 years ago

Now as soon as I open a notebook the CPU goes 100% without evaluating anything. It evaluates expressions but there's a Mathematica process that keeps on taking 100% CPU

Ludwiggle commented 5 years ago

Still high CPU usage, not 100% anymore but much higher than Mathematica or command line interface.

@Ludwiggle is this okay to close? Have you encountered any further bugs?
