I experienced problems installing pyopencl via conda. It seems the dependency ocl-icd does not play nicely with AMD OpenCL drivers. One solution I found is to remove ocl-icd
1) install pyopencl via conda (also installs all dependencies) 2) uninstall ocl-icl via conda 3) reinstall pyopencl: conda install pyopencl -c conda-forge —no-deps hope that helps Gregor > Am 05.11.2019 um 09:55 schrieb Kühn-Kauffeldt Marina > <marina.kuehn-kauffe...@unibw.de>: > > Hi, > > I am fairly new to opencl and I'm currently trying to get PyOpenCL to work in > order to use an other python based package (pysph). > I have done the following steps for the installation > > -installed CentOS 7.6 > -installed Radeon VII OpenCL drivers (sudo required) > -installed miniconda with python 3.7 without sudo > -created conda environement > - installed pyopencl (tried via conda-forge and pip) > > when I try to run the following minimal example in the conda environment > > import pyopencl as cl > > platforms = cl.get_platforms() > > ctx = cl.Context(dev_type=cl.device_type.GPU, > properties=[(cl.context_properties.PLATFORM, platforms[0])]) > print(ctx.devices) > > > I get the following error > File "test.py", line 5, in <module> > ctx = cl.Context(dev_type=cl.device_type.GPU, > properties=[(cl.context_properties.PLATFORM, platforms[0])]) > pyopencl._cl.RuntimeError: Context failed: DEVICE_NOT_FOUND > > > I could not find any solution in the installation instructions or by googling > or searching the the error message in the Mailing list.
