This is a known issue with CUDA 9.1 and the new Turing generation of GPUs. You don't need to do anything except ignore the initial warning or error.
There are multiple issues. The warning about recompiling of libraries is spurious and not relevant. The error from cublas is one-time only. And there is an equivalent error in cuDNN. A permanent workaround is to put the following into your startup.m file:
