title: SegNet - CUBLAS_STATUS_SUCCESS (11 vs. 0) CUBLAS_STATUS_MAPPING_ERROR
body: <p>Im trying to train my own dataset on SegNet (with caffe), I prepared the dataset same as <a href="http://mi.eng.cam.ac.uk/projects/segnet/tutorial.html" rel="nofollow">segnet tutorial</a>. when I try to run the train, it shows me this error:</p>
