ipex 2.2.0 "import intel_extension_for_pytorch" gives "Illegal instruction (core dumped)" on Ubuntu 22.04 and J4105 CPU

[sanderjo]

Describe the bug

Looks like #235 but for ipex version 2.2.0:

sander@brixit:~$ python3 -c 'import intel_extension_for_pytorch as ipex'
Illegal instruction (core dumped)

sander@brixit:~$ python3 -c 'import intel_extension_for_pytorch._C as core'
Illegal instruction (core dumped)

sander@brixit:~$ python3 -c 'import torch; import intel_extension_for_pytorch'
Illegal instruction (core dumped)

sander@brixit:~$ pip show intel_extension_for_pytorch

To show my python3 is OK:

sander@brixit:~$ python3 -c "print('hello')"
hello

Versions

sander@brixit:~$ python3 collect_env.py
Illegal instruction (core dumped)

Or is this a hint / cause:

sander@brixit:~$ python3
Python 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import torch
>>> torch.__version__
'2.2.1+cu121'
>>>

"cu" ... is that cuda? Which I don't have?

Hello, Intel(R) Celeron(R) J4105 CPU was brought to market in 2017/2018, and only has 4 CPU cores. Intel extension for pytorch might not support this SKU of CPU.

[sanderjo]

I know. But do you think a "core dumped" is the wanted behaviour? I would expect something more graceful.

[YuningQiu]

Hello, thanks for bringing this up. Actually, "core dumped" is a general/routine error when reported for this type of issue.

[YuningQiu]

Hello, thanks for your suggestions, and we will take them into considerations.
