if not avx_supported() and libpaddle.is_compiled_with_avx():
NameError: name 'libpaddle' is not defined
解决方案：
请检测你的机器cpu是否支持AVX指令 cat /proc/cpuinfo | grep -i avx，paddlepaddle2.5以及之后，不在支持noavx设备。
如果不支持请根据以下进行安装，具体文档可参考官方说明
首先使用如下命令将 wheel 包下载到本地：
cpu、mkl 版本 noavx 机器安装：
python3 -m pip download paddlepaddle==2.4.2 -f https://www.paddlepaddle.org.cn/whl/linux/mkl/noavx/stable.html --no-index --no-deps
cpu、openblas 版本 noavx 机器安装：
python3 -m pip download paddlepaddle==2.4.2 -f https://www.paddlepaddle.org.cn/whl/linux/openblas/noavx/stable.html --no-index --no-deps
