问题描述

我正在尝试在Anaconda的GPU中使用pyopencl。但是找不到设备。在Python中，我得到以下输出：

>>> import pyopencl as cl
>>> cl.get_platforms()
[<pyopencl.Platform 'Clover' at 0x7f3569088100>]
>>> cl.get_platforms()[0].get_devices()
[]

另外，当我运行sudo clinfo时：

Number of platforms                               1
  Platform Name                                   Clover
  Platform Vendor                                 Mesa
  Platform Version                                OpenCL 1.1 Mesa 18.0.5
  Platform Profile                                FULL_PROFILE
  Platform Extensions                             cl_khr_icd
  Platform Extensions function suffix             MESA

  Platform Name                                   Clover
Number of devices                                 0

NULL platform behavior
  clGetPlatformInfo(NULL, CL_PLATFORM_NAME, ...)  Clover
  clGetDeviceIDs(NULL, CL_DEVICE_TYPE_ALL, ...)   Clover
  clCreateContext(NULL, ...) [default]            No devices found in platform
  clCreateContextFromType(NULL, CL_DEVICE_TYPE_CPU)  No devices found in platform
  clCreateContextFromType(NULL, CL_DEVICE_TYPE_GPU)  No devices found in platform
  clCreateContextFromType(NULL, CL_DEVICE_TYPE_ACCELERATOR)  No devices found in platform
  clCreateContextFromType(NULL, CL_DEVICE_TYPE_CUSTOM)  No devices found in platform
  clCreateContextFromType(NULL, CL_DEVICE_TYPE_ALL)  No devices found in platform

ICD loader properties
  ICD loader Name                                 OpenCL ICD Loader
  ICD loader Vendor                               OCL Icd free software
  ICD loader Version                              2.2.8
  ICD loader Profile                              OpenCL 1.2
    NOTE:   your OpenCL library declares to support OpenCL 1.2,
        but it seems to support up to OpenCL 2.1 too.

OCL驱动程序：

我安装了nvidia-opencl-icd-410软件包的最新版本，并将文件mesa.icd从/ etc / OpenCL / vendors复制到/ usr / lib / anadonda3 / etc / OpenCL / vendors，如{{3 }}。

这是文件的内容：

libMesaOpenCL.so.1

我可能会丢失一些东西，如果有人可以帮助我，我会很高兴！

编辑：

由于PyOpenCL似乎是使用conda安装的，因此有另一种可能性来检测系统范围内的OpenCL ICD，例如： Nvidia将运行：

conda install ocl-icd-system

如以下建议：https://documen.tician.de/pyopencl/misc.html

PyOpenCl的pip版本可以检测到其中的ICD

/etc/OpenCL/vendors

直接。

还要确保正确安装了nvidia驱动器。如有疑问，请使用软件包管理器重新安装驱动程序，并在安装后重新引导系统。
