Hi AthiraM_Intel,

as i become aware the first time the problem, I've updated to patch2 from tarball l_pythoni3_p_2020.1.893 . After installation without any errors i upgraded the complete intel parallel studio cluster edition to parallel_studio_xe_2020_update1_cluster_edition above fresh installed parallel_studio_xe_2020_cluster_edition. Also without errors.

Now get idea,

as I remeber starting interactive python shell I got no module named readline. Then I installed readline using pip.  Since this time the coredumps occures. Now checked with spyder3 . works without any errors. Then i 've removed readline and make some tests codes  and it works on pythonshell, but the startup of the shell gives error about missing readline again but ignored.  May be intelpython does not use readline from pip but from Intelpath ?

Have we to modify the /etc/pythonstart ?   Or to remove the IPYTHONSTARTUP varable points to ?

Hi Thomas,

Sorry for late response.

Intel distribution for Python doesn't include readline, and you get readline from public pip channel instead of intel channel.

For your core dump issue, it should be related to your gcc compilation process.

Can you try below steps for using readline python module?

1. pip install gnureadline
2. pip uninstall readline

Above steps work on my Intel Python environment.

Let us know if it works for you or not.

regards

Louie

Hi Louie,

thanks a lot.

Works for me too.

Perfect, but should Intel distribution not contain  the right readline (gnureadline) per default ?

Anyway, this thread can be closed.

Hi Thomas,

we will feedback this issue to Intel Python release team, and discuss with them to have proper readline in Intel python release in the feature.

will close the ticket for now.

thanks
