----------------------------------------------------

Hey [~hiwayne],

Sorry for not replying soon enough. I had a lot of work and did not get a chance to test the
program till yesterday.

And YES it runs with out any problem.

However, when I train a alexnet without batchnorm, within first batch the loss if going to
*nan*.
So I tested with +squared errors loss+ and +no softmax activation+.
I started to get loss ~= 0.35 and acc = 14%, how much ever train the model.

> Hello I came across the framework when I was searching for a deep learning framework
with opencl support.
> I cloned the GITHUB master branch version and downloaded as shown on the install page.
> After sucessful install, I tried to run cifar-10 example with opencl instead of CUDA,
I am receiving following errors:
> WARNING: Logging before InitGoogleLogging() is written to STDERR
> F0127 17:07:02.757550 27607 opencl_convolution.cc:30] Check failed: input.device()->lang()
== kOpencl (0 vs. 2)

> Aborted (core dumped)
> I am new to this and I am learning as I go.
