Segmentation fault on tab completion

JackReid — Wed, 15 Feb 2023 12:37:54 GMT

Having installed the Intel Distribution for Python on several Linux machines, I consistently see segmentation faults when pressing the Tab key in an interactive session. In each case, the problem arises with Python 3.9 or 3.10, but not with Python 3.8.

Python 3.9.15 (main, Nov 11 2022, 13:58:57) [GCC 11.2.0] :: Intel Corporation on linux Type "help", "copyright", "credits" or "license" for more information. Intel(R) Distribution for Python is brought to you by Intel Corporation. Please check out: https://software.intel.com/en-us/python-distribution >>> Segmentation fault (core dumped)

Variously, the computers have operating systems:

CentOS 7
Alma Linux 8.6 (in the Fedora family)
Red Hat Enterprise Linux Server 7.9
Rocky Linux 8.6 (also in the Fedora family)
Scientific Linux 7.9 (also in the Fedora family)
CentOS 7

While I appreciate that these older operating systems are not all listed as supported, some are newer, but still affected.

Although I note the issue here , regarding AMD processors not being supported, these machines have, respectively:

Intel Core i7
Intel Core i7
Intel Xeon E5
Intel Xeon Platinum 8368Q
Intel Xeon Gold 6142
Intel Xeon Gold 5120

None of these problems arise with an installation on Windows, where it is working very well.

I should be grateful for any advice on how to remedy this. Could this be the same problem as in the previous post (despite the different processors and operating systems)?

Hello,

Could you please tell which version of Intel Distribution for Python are you using and seeing segfault? Starting from 2022.1 version, CentOS 7 and RH7 OSes are deprecated and this info is documented in Release Notes that you can find in https://www.intel.com/content/dam/develop/external/us/en/documents/2022.2_Python_Release_Notes_Intel(R)_Distribution_for_Python.pdf

Thank you

Thank you for your reply.

While I noted that some of the operating systems are now listed as deprecated, I found the same problem with some other, newer operating systems that are not so listed.

Originally, I installed Intel Python from a Miniconda installation via the Intel channel. By default, it downloaded the most recent version, namely 2023.0. However, on forcing a downgrade to 2022.0 on the first machine (CentOS 7), which predates the deprecation, I find that the issue recurs.

Hello,

I reproduced the issue on CentOS 7 with IDP 2022.0 version as you noted. I will escalate this issue with our IDP team.

Thank you

Hi,

please run "conda uninstall pyeditline --offline" in IDP environment.

This should resolve the segfault issue.

Please let us know if it doesn't.

Thank you.

Thank you for your reply. Indeed, this does appear to work, and I am now able to use tab completion in the usual way.

Thank you for all of your help and advice.

Best regards,
