How to fix 'File '/path/to/datasets/VOC2012/ImageSets/Segmentation/val.txt' not found'?

[b2220333]

When I execute ./sam_eval_all.sh which just change to use python2.7 , it shows:

How to solve it? Thank you~

Maybe I wasn't clear enough in the README '/path/to/datasets' should be a path pointing to where you stored the VOC2012 dataset, for example '/data' or something similar...

[b2220333]

Does this error mean before I run the first example(./sam_eval_all.sh ), I should download VOC2012 dataset and set the system variable 'DATA_DIR' to the absolute path of dataset? Thank you~

[philkr]

Yes you should download the VOC2012 dataset and then point the cmake variable DATA_DIR to its location.

[b2220333]

I add: set (DATA_DIR "/home/sam/code/download/CNN/caffe/caffe/data/ilsvrc12")

I try to use caffe/data/ilsvrc12:

mkdir -p VOC2012/ImageSets/Segmentation/ cp val VOC2012/ImageSets/Segmentation/ cp * VOC2012/ImageSets/Segmentation/

and finally, it passed and also show nothing: sam@sam:~/code/download/Segmentation/lpo/src$ bash sam_eval_all.sh sam@sam:~/code/download/Segmentation/lpo/src$

Is that normal? Thank you~

Rodrigo's PR #10 should address this. We now have more verbose error messages. You might also confuse the imagenet and pascal datasets...
