OpenCL version 1.2?
I am trying to run LightGBM library (https://github.com/Microsoft/LightGBM/w … tion-Guide) with GPU support enabled (940MX). Compilation goes just fine but when I try to import in python the library I get the following message
OSError: /usr/lib/python3.6/site-packages/lightgbm/lib_lightgbm.so: symbol clCreateCommandQueueWithProperties, version OPENCL_2.0 not defined in file libOpenCL.so.1 with link time referenceAs far as I understand 940MX supports only OpenCL version 1.2. Does it mean that I need to downgrade OpenCL? How can I do it?

Re: OpenCL version 1.2?
What videocard and driver are you using ?

Re: OpenCL version 1.2?
That confirms your system is running OpenCL version 1.2 correctly on your nvidia gpu .
Are there other videocards on your system ?
The installation guide clearly mentions OpenCL 1.2 as requirement, I think you should create an issue on their github site.
