我按照以下说明在新安装的Ubuntu 18.04上安装了ROCm，ROCm-Tensorflow和PlaidML：
虽然两个GPU都被/opt/rocm/bin/rocminfo列出，但/opt/rocm/opencl/bin/x86_64/clinfo或plaidml-setup却无法识别它们（下面的输出）。
导入tensorflow会引发以下错误：
>>> import tensorflow

参考ROCm文档，我相信rx470可以使用它，而iGPU vega 8则不能。 请参考此链接以获取更多信息。 https://rocm.github.io/hardware.html
答案 1 :(得分：0)
嗯，您的设置存在一个明显的问题：
平台数量：1
平台名称：便携式计算语言
平台供应商：pocl项目
设备类型：CL_DEVICE_TYPE_CPU
您仅安装了一个平台，而没有AMD的平台。 Ubuntu / Debian中的Pocl平台只能使用CPU。您需要为ROCm安装AMD的opencl软件包。描述here，但基本上是：
sudo apt-get install rocm-opencl-dev
应该工作。如果安装正确，clinfo输出中的“ Platform Vendor”将显示“ Advanced Micro Devices，Inc。”。
