illegal instruction (core dumped)

Hi,

I'm trying to use the Intel Python on Linux.

When I try to import numpy or scipy, I receive the message: Illegal instruction (core dumped).

I found similar problem in forum but it is not helpful for me.

thanks

Hal,

Thank you for trying the Intel(R) Distribution for Python.

Can you send me more information about your configuration?

Which version of our python distribution are you using?
Which Linux distribution/version are you using?
What steps did you take to setup your python environment? In particular, what are PYTHONHOME and PYTHONPATH?

Thank you,
Todd

Thank you Todd for answer.

I'm using CentOS 6.7 and I tried both of Python 2.7 and 3.5, Intel Distribution of Python Update 1 and 2 (4 Cases).

I didn't set environment PYTHONHOME and PYTHONPATH.

I followed release notes, that are some installation steps and 'source /opt/intel/intelpython*/bin/activate'.

thanks.

Hyeonggu,

Please post or private message me the results of:

cat /proc/cpuinfo

If we see which cpu you have, we can try to reproduce the problem.

Intel Python requires SSE 4.2 to run and your CPU does not have it. An easy way to check is to look for sse4_2 in the /proc/cpuinfo. The wikipedia article (https://en.wikipedia.org/wiki/SSE4) describes which CPU's have SSE4.2.
