想赶上机器学习ML深度学习的热潮不容易，光是显卡就是一笔不小的投入。网上搜索了一下，见A卡也可以勉强用于ML，遂想用手头有的一张A卡（RX470）进行学习，过程不易，记录之。

一、试用WSL2，失败。

    到AMD ROCM​​官网​​查看，不支持windows平台，基本上推荐Ubuntu，心想正好在windows10上安装WSL2，最新版已经升到20.04，过程不赘述。安装好anaconda和ROCM后，rocminfo查看，报告找不到GPU，网上搜索后，确定wsl暂时（据微软说，解决方案正在研发中）不支持直接访问硬件，所以本方法失败。

二、物理机安装ubuntu20.04

按照教程安装rocm和anaconda 后， 安装tensorflow-rocm。安装很顺利，一切就绪，进入python，import tensorflow，报错！

又经过一番艰苦卓绝的搜索：），终于发现正确解决方案，竟然只是安装 rocm-libs！



suso apt install rocm-libs


但是由于rocm-libs的库文件都安装在/opt/rocm-4.3.0下面的多个子路径中，因此需要条件到LD路径中。

我这里采用的时在/etc/ld.so.conf.d下面创建一个新的独立配置文件 rocm_4.3.0_libs.conf



/opt/rocm-4.3.0/lib
/opt/rocm-4.3.0/rocsolver/lib
/opt/rocm-4.3.0/rocblas/lib
/opt/rocm-4.3.0/rocclr/lib


再次进入python导入tensorflow，终于Ok了！
