I installed ROCm, ROCm-Tensorflow and PlaidML on a fresh installation of Ubuntu 18.04 using the instructions given on:

While both GPUs are listed by /opt/rocm/bin/rocminfo, they are not recognized by /opt/rocm/opencl/bin/x86_64/clinfo or plaidml-setup (Output below). Importing tensorflow throws the following error:

参考 ROCm 文档,我相信 rx470 可以使用它,而 iGPU vega 8 则不能。请参阅此链接以获取更多信息。 https://rocm.github.io/hardware.html

好吧,您的设置存在一个相当明显的问题:

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

你只安装了一个平台,它不是 AMD 的。Ubuntu/Debian 中的 Pocl 平台只能使用 CPU。您需要为 ROCm 安装 AMD 的 opencl 包。这在此处进行了描述,但基本上是:

sudo apt-get install rocm-opencl-dev

应该管用。如果安装正确,clinfo 输出中的“Platform Vendor”将显示“Advanced Micro Devices, Inc.”。
