This is a similar issue to ProRender for blender Rendering not showing anything,[pc, windows 10, all drivers up to date and my ... , but
on Linux and with Nvidia card 
First I must mention that this is on a unsupported Linux distribution, so I don't expect the developers attention (I suspect they have their hands full already),
this is more of a possible bug report for reference.
Some version info:
- RPR version 1.7.212 (core 1.312)
- Nvidia GT-640 (yes, I know , can't afford AMD at the moment) binary driver 396.54
clinfo shows it as OpenCL-1.2 capable
Installing rpr was pretty straightforward:
- extract the .run file
- install the addon from within Blender
- activate it
- add RPR_MATERIAL_LIBRARY_PATH as a environment variable
(couldn't figure out the proper path to copy it too, rpr in Blender kept complaining that it can't find it
without setting env variable).
Since the version of Blender (2.79 built from upstream master branch (I can dig up the exact commit, if you are interested)) is
using system python3, I removed cffi_backend.cpython-35m-x86_64-linux-gnu.so and libffi-72499c49.so.6.0.4
libraries from rprblender directory (system versions are 1.3.1 and 3.2.1).
Btw, I've seen in install.py embree and openimageio as dependencies.
I do have openimageio-1.8.14 installed, but no embree.
Two issues:
- Can't apply any materials (object just turns bright white)
- When I try to render, blank page with the 'Check log for details' shows
I think this is the relevant portion from the rprblender.log

If you need more logs or any other additional information, just ask
RPR looks very interesting, I'd love to play with it sometime.
And kudos for making it vendor-neutral, even though some vendors are not particular fans of OpenCL *khm**khm*

So I do not know NVidia drivers on linux as well, but is there a way to verify that the driver that you have supports OpenCL?
That is what is confusing me about this.
Several other applications that also use OpenCL work fine, and their opencl tests show no errors,
like Darktable or Gimp.
Here is the output of clinfo, you might spot something fishy/missing in it

I have CUDA-9.2 installed, since I use it for Cycles in Blender, if that's relevant.
I forgot to say before, but the same thing happens if I use the official Blender binary, I just modified
install.py not to install packages, since this is not a Ubuntu machine.
