oclUtils error at host processor mode.

[tokohito]

Hello

I am trying to use KNLMeansCL on virtual machine. Of course, no physical video card is installed in the virtual machine, I specified KNLMeansCL paramater as device_type="cpu". Unfortunately, the following error is output and AVS can not be executed.

avs [error]: KNLMeansCL: fatal error! (oclUtilsGetPlaformDeviceIDs: OCL_UTILS_UNKNOWN_ERROR)

Please fix this problem.

Windows10 version1803(virtual machine) Microsoft Basic Display Adapter(vitual video card driver) Avisynth 2.6.0 KNLMeansCL v1.1.1

Thank you.

Hi tokohito, I've never tried to use a program from a virtual machine. However, even the use of CPU requires driver installation.

Oh, I am troubled... :-( Can you change to skip the processing of detect video devices, when KNLMeansCL "device_type" param is set to "cpu" ?

[tokohito]

I'm sorry. As a result of I installing "Intel OpenCL Drivers and Runtimes", the errors are no longer output. However, execution speed is too slow from a virtual machine. (0.03fps) :-o I need a different approach for realistic use. Thank you.

using Windows 10pro 1909 (Build 18363.657) with an AMD Ryzen 7 1800X and a Geforce GTX 1070 Ti driver version 442.50 with Avisynth+ 32bit I get:

LoadCPlugin("I:\Hybrid\32bit\AVISYN~1\ffms2.dll")

# denoising using KNLMeansCL
KNLMeansCL()
return last

KNLMeansCL: fatal error!  (oclUtilsGetPlaformDeviceIDs: OCL_UTILS_UNKNOWN_ERROR) (C:\Users\Selur\Desktop\test.avs, line 5)

funny thing is that using KNLMeansCL in Vapoursynth 64bit works fine.

I want to use KNLMeansCL in docker and meet the exact same problem. Then I fixed it by install a intel_sdk_for_opencl_applications, which can be download here When use clinfo in shell I got this output, this is wanted output
