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()
[]
同样当我运行
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here所述。
这是文件的内容：
libMesaOpenCL.so.1
我可能会缺少一些东西，如果有人可以帮助我，我会很高兴！
最佳答案
编辑：
由于PyOpenCL似乎是使用conda安装的，因此另一种可能性可以检测例如Nvidia将运行：
conda install ocl-icd-system
如https://documen.tician.de/pyopencl/misc.html所建议
PyOpenCl的pip版本可检测到ICD
/etc/OpenCL/vendors
直。
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。
