Building Caffe: unset variable CUDA_cublas_device_LIBRARY breaks CMake build configuration

[monocongo]

I am trying to build Caffe as one of the prerequisites for DIGITS and at the step where I use CMake to configure the build:

Can someone advise as to how I can get past this issue? Thanks in advance for any assistance.

CUBLAS is apparently not installed on your system. Or it could be related to this issue, i.e. some old version of CMake. https://stackoverflow.com/questions/54347530/how-to-link-cublas-library-with-cmake-cuda-10-0-ubuntu-18

Thanks, @Olyseus. Is CUBLAS supposed to be included as part of the CUDA installation, or is it normal to need to install it separately? This is where I should install it from, correct?

[monocongo]

I followed these instructions to reinstall CUDA 10.1, as well as sudo apt autoremove that removed CUDA 10.0. I updated my CUDA_HOME to /usr/local/cuda-10.1 and now the CMake configuration doesn't even find CUDA (and the CUBLAS libraries don't appear under /usr/local/cuda-10.1/lib64):

Hi，I also have the same problem. Is there any way to solve it?
