Error with Cublas_v2 on build

[skyler14]

I've been trying to build the caffe library as mentioned during the steps in the readme but I keep getting errors in relation to a part of blas called cublas_v2 not being able to be imported when I use the make file in the script. How should I proceed, here is the full output:

Dear skyler14,

According to BVLC/caffe#2704, you may need to do a clean build or build using make Q= to debug.

Thanks

I've tried using make clean and remaking, and I dont quite understand how make Q= does anything different or if I used it properly, output seemed the same when i did make Q= all -j 4 . Should I be able to run the make command without modifying Makefile.config at all or what specific changes are required between every system?

Dear skyler14,

I am afraid that your Cuda environment has some issues. Please check that before re-modify the Makefile.config.
