OpenCL support for Pavilion 15-cs3xxx

HP Recommended
Pavilion 15-cs3xxx
Microsoft Windows 10 (64-bit)

I recently purchased a Pavilion 15-cs3xxx for a class.  When I ran a program, I received an error "clCreateContext(): CL_DEVICE_NOT_AVAILABLE".  I google and it seems to be related to OpenCL support. I checked the BIOS (no option to select video processor), updated firmware using hp support assistant but error still persisted. My course mates did not have such issue. I was also able to run on another hp elitebook.

Any suggestions how I can resolve the issue?

Thanks.

Running the following command does not show either the Intel onboard Iris Pro or the Nvidia GeForce Mx250 GPU:
