Cannot create Cublas handle

[Chad Cordes]

Gooday,

I am attempting to run a demo.py with my local Caffe build, but am getting the following error in python shell when attempting to set the gpu:

In python shell:

caffe.set_mode_gpu()

WARNING: Logging before InitGoogleLogging() is written to STDERR
E1020 14:06:47.083652 23219 common.cpp:114] Cannot create Cublas handle. Cublas won't be available.

Could someone kindly provide some guidance on how to address this issue?

Caffe build passes make runtest with no errors. System and build details below. Sincere thanks for any support.
