Resolving Path Error - Check failed: mdb_status == 0 (22 vs. 0) Invalid argument

[Ben Nguyen]

From what I've read this is a path error but for the life of me can't figure out what is the problem..

My train.sh and all the _solver/_deploy/_train_test.prototxt files are in this folder: 

/home/guest/temp

but when I execute ./train.sh 

( 

TOOLS=$CAFFE_ROOT/build/tools

$TOOLS/caffe train -solver cifar10_solver.prototxt

)

I get the dreaded check failed error : output/cifar10/dataset_mean.binaryproto

Note, the $CAFFE_ROOT points to /home/guest/caffe

The only paths in solver.prototxt file is for the net file and snapshot prefix folder:

cifar10_train_test.prototxt

output/cifar10/snapshots/cifar10

both of which I verified exist and are r/w by all:

/home/guest/temp/cifar10_train_test.prototxt

/home/guest/temp/output/cifar10/snapshots/cifar10

 

While the contents of the cifar10_train_test.prototxt file refers to:

output/cifar10/dataset_mean.binaryproto

output/cifar10/dataset_mean.binaryproto

output/cifar10/db/training_lmdb

output/cifar10/db/testing_lmdb

again both files and folders are present and r/w by all.   What could be wrong in the paths?   I can't imagine the train.sh and prototxt files have to be in under the $CAFFE_ROOT folder, does it?   

It's the only thing I can think of since all my user files are in their own folder but caffe maybe looking for everything relative to $CAFFE_ROOT?
