pycuda: Missing libdevice file for compute_30.


my setup is as follows:
hardware: x86_64, GeForce GTX 650
software: CentOS 7, kernel 3.10.0-693.2.2

I installed nvidia drivers and cudatoolkit 9.0 from nvidia web site, then installed pycuda and numba over python3.4. Installation path is /usr/local/cuda/nvvm

While evaluating a python program, I get
RuntimeError: Missing libdevice file for compute_30.
Please ensure you have package cudatoolkit 7.5.
Install package by:

conda install cudatoolkit=7.5

It seems the driver is searching for a file with name libcompute30.bc; the only installed file is /usr/local/cuda/nvvm/libdevice/libdevice.10.bc

Did something fail during the isntallation ? Is there some way to get rebuild the missing drivers ?
