I am new to caffe. To train Lenet with mnist dataset,I downloaded the data to the data/mnist in caffe. When trying to convert to lmdb, using ./examples/mnist/create_mnist.sh , I get error as :

 Creating lmdb...

Can somebody help me with this? What exactly could be the issue?

Did you download mnist, via the

./data/mnist/get_mnist.sh

command? Reading the docs sometimes really helps...
