Hi , 

I do have a similar problem.

I am using a NVIDIA GeForce RTX 2060 graphic cards.

I have read that even though it is not among the recommended graphic cards for the GPU acceleration it should anyway work.

Not as well as with a Quadro or Tesla card I presume but still.

I set up the environment variable ANSGPU_OVERRIDE to 1 .... still not enabling the library ...

Any idea ?
