Caffe MNIST Tutorial Error

caffe_mnist_tut_error.txt

I am attempting the MNIST tutorial and having an error when I attempt to create the lmdb data set. Retrieval goes fine, but in creation I have:

perdue@gpu1> ./examples/mnist/create_mnist.sh

I'm not sure what error code 5 means. Is it a general I/O error? When I run the script, it creates lock files in the examples/mnist area, but that is all
