2020-05-03 19:20:24 +0200 commented answer Multiprocess hangs

There is a fix in the notebook to avoid multiprocessing but that one does not work either (at least not out of the box). I tried running SageMath on my MacBook and it fails as well on the parallelisation, albeit slightly differently. I managed to get it to work by installing Ubuntu 18.04 (needs some fixes to get Firefox to draw graphs, etc.).

I am using SageMath 9.0 on Windows 10 (in admin mode) and following this example.

Everything runs fine until In [43] where the progress bar appears but stops 1/4 through and hangs. I can see some Python processes running in the background (via the Task Manager) and the CPU and memory usage reaches 80% continuously. If left for an hour, nothing happens until I kill all processes and restart.

Anyone has encountered the same issue and has a fix?

Thanks a ton - this works indeed!

2020-04-27 14:23:56 +0200 asked a question Plot not working

I am new to SageMath and am following the examples from the basic tutorials. The following command does not work:

plot3d(x^2 + y^2, (x,-2,2), (y,-2,2))

The error message is

sh: -c: line 0: syntax error near unexpected token `(' 
sh: -c: line 0:`sage-open/Users/xxx/.sage/temp/MacBook-Pro-(6)/1333/tmp_smrlkile.html 2>/dev/null 1>/dev/null &'

Browsing to the temp directory, I do find the .html file and can open it (it displays the right graph). It seems the viewer cannot open it from the terminal application of SageMath. Is this due to the presence of parentheses in the auto-generated temporary directory? If so, how can I changed it?
