ERROR: Cannot access file model/ilsvrc12_mean.hdf5

[memoiry]

I followed "Image Classification with Pre-trained Imagenet CNN" instruction and was stuck while trying to implement julia > net = Net("imagenet", backend, layers)

it follows

what's wrong, is there any package I have not installed?

thx for help

You need to run the script in that folder to download pretrained model first.
