Hi

this is to report that with 2022.2.1 version of Intel python interpreter, typing <TAB> for completion segfaults.

No problem with previous version

Hi Stephane,


This command may solve your segmentation fault issue. Give it a try.


conda uninstall pyeditline --offline


Best,

Alex

Hi,


Thank you for posting in Intel Communities.


In order to reproduce your issue, could you please share the below details.

  1. OS Details.
  2. Processor Details.
  3. Are you running Intel Python on any virtual machine?


Thanks,

Aayushi

Hi thank you for answering

- the problem occurs on both CentOS Linux release 7.9.2009 (Core) and CentOS Stream release 8

- x86_64: Intel(R) Xeon(R) Silver 4216 CPU @ 2.10GHz and AMD EPYC 7272 12-Core Processor

- test is on bare metal

Cheers,

Stephane Rouberol

Hi,

 

Since Centos 7.9 is deprecated you are facing this issue, we were able to install and run Intel Python on Centos 8 without any issues. Attaching screenshot for your reference.

Hi

imho your screenshot is not linked to the raised problem.

Did you try <TAB> as first python cmd as described in my first report?

BTW I am astonished by your statement about CentOS 7 being deprecated

since it is the most recent version of 7 and

https://www.intel.com/content/www/us/en/developer/articles/release-notes/distribution-for-python-release-notes.html 

2022.3.1 cites indeed CentOS 7 as supported

 

Thanks for your feedback anyway

Hi,

 

The 2022 release of Intel Python mentions CentOS 7 in the list of deprecated OS. PFB screenshot for your reference.

AayushiR_Intel_0-1671533022169.png

 

 

We were unable to reproduce your segmentation fault issue with <TAB> as we had issues while installing in CentOS 7. 

But we were able to install successfully in CentOS 8 without issues and <TAB> is working fine. Please try in CentOS 8 and let us know if the issue still persists.

 

Thanks,

Aayushi

Hi,

 

We tried it on the Cascade Lake machine with CentOS 8, and it is working fine. We'd like to know whether your CentOS 8 machine is having Intel or AMD processor.

Hi,

 

We tried from our end It's working fine with Intel Processor. Intel Distribution for Python doesn't support AMD Processor. Please refer below screenshot and link.

Hi

OK, as stated before, tab works OK with 2021.1.1-44 on AMD

so this is a regression.

I understand that since most of my hw is AMD now, I won't get any support form this canal.

Unsolved for me!

Hi Stephane, I have taken over your case. I've read the posts and here's my understanding so far:

 

  • The issue you are facing is you get a segmentation fault when you press 'tab' on Intel Python 2022.2.1 but no issue on 2021.1.1-44
  • You saw this on CentOS 7.9 and 8.5 on an AMD EPYC processor

 

From Aayushi's responses and my understanding, your original setup does not meet the hardware and software requirements to use Intel Distribution for Python. You addressed the software requirement by upgrading to CentOS 8. But since you are using an AMD EPYC processor, this problem is outside of our scope.

 

As a developer myself, I understand the inconvenience this causes you but Intel Distribution for Python is designed for Intel Core and Xeon processors. Hardware and software continually get updates, and sometimes certain features are no longer supported. It is interesting that you're able to get Intel Distribution for Python 2021.1.1-44 working to some extent. Your options are to avoid using 'tabs' on 2022.2.1, go back to 2021.1.1-44, or try using another version.

 

Let me know what you think.

 

Best,

Alex

Hi

As I suspected, the problem does not seem to be cpu related.

I could run the same test on an Intel RHEL 8.7 clone server, with same behaviour:

Rocky Linux release 8.7 (Green Obsidian)

I noticed your Python versions are different. Can you try using Intel Distribution for Python 2022.2.1 with Python 3.7.11? Python 3.7 is what you had before. Let's minimize the differences between the setup.

Hi

FYI a vanilla python v3.9.16 built from sources with all default options on Intel(R) Xeon(R) Silver 4216 CPU @ 2.10GHz behaves differently:


- at prompt <tab> completion has no effect

Hi Stephane,


Thank you for your patience.


I have discussed this with my team and because Intel Distribution for Python is not supported on AMD EPYC, we are not able to provide a solution for you at this time and I will be closing this ticket. I have submitted a feature request to one of our internal teams. Keep an eye out for new releases of Intel Distribution for Python that may offer support.


As of now, we only test Intel software on Intel hardware, but if that changes, I will respond to this thread. This thread will also stay open.


Best regards,

Alex

Hi

Imho the "not supported on AMD EPYC" does not apply since I took the pain to show the pb is present with Intel processors as well

It is clearly a regression from intelpython 2021.4.0.3353

Accepted solution? Hum.

Hi Stephane,


The Intel Xeon processor you're using is CPU E5-4650 v4, which is not in the hardware requirements for Intel Distribution of Python, which is part of the Intel AI Analytics Toolkit. You need to use the Core Gen10 or Xeon Scalable according to the hardware requirements:
