Error:neon --gpu nervanagpu examples/convnet/i1k-alexnet-fp32.yaml about neon HOT 5 CLOSED

Do you have the imagenet data files (the tar files containing the images)?
They are not distributed as part of neon, but you need to get them from
ilsvrc in order to run the imagenet example.

from neon.

yes, I have it and change the path of -fp32.yaml .

from neon.

can you confirm that the following files are in $repo_path/I1K (where
repo_path is set as specified in the yam file):

ILSVRC2012_img_train.tar
ILSVRC2012_img_val.tar
ILSVRC2012_devkit_t12.tar.gz

from the error it seems like the batch_writer is not finding the train tar
file.

from neon.

cool. it works!

from neon.

a little suggestion: maybe we should provide meanful debug/error message. ;)
