环境：centos7  python3.8.11 gcc8.2.0 安装paddlepaddle2.1.1   机器支持 avx2指令集

问题：

1、根据官网指导: python -m pip install paddlepaddle -i https://mirror.baidu.com/pypi/simple 安装后：

运行python，import paddle出现：Illegal instruction 错误

2、改安装no-avx版本，

运行python，import paddle出现：
WARNING: AVX is supported on local machine, but you have installed paddlepaddle without avx core. Hence, no_avx core which has worse preformance will be imported. You could reinstall paddlepaddle by 'python -m pip install --force-reinstall paddlepaddle-gpu[==version]' or rebuild paddlepaddle WITH_AVX=ON to get better performance. The original error is: No module named 'paddle.fluid.core_avx'

再用'python -m pip install --force-reinstall 又回到第一种错误
