Illegal instruction (core dumped) when importing

[Yujikaiya]

Operating System: CentOS 7
Python version: 3.7.9 (from anaconda)
gcc-c++-4.8.5 (Since there was another issue about C++ environment, so just for sure)

Description
I installed Gryffin successfully by using pip, but when import Gryffin in the python code, it's shut down with the error message "Illegal instruction (core dumped)".

I succeccfully use Gryffin in the environment below.
Operating System: Ubuntu 18.04
Python version: 3.7.9 (from anaconda)
gcc version 7.5.0

I would like to have some information about using Gryffin with CentOS.

I found out that this error occurs because of the old CPU which does not support AVX, so illegal instruction occurs when Tensorflow is imported (I confirmed by imoporting Tensorflow only).

So, command below fix the issue.
pip uninstall tensorflow
conda install tensorflow

To meet the compatibility of the Tensorflow (2.3.0)
I also need to import right version of tensorflow-probability
pip install tensorflow-probability==0.11.1
(v. 0.10.0 and 0.11.0 does not work)
