Hello All,

I received the following error while I was training the data. I have tried all the solutions given on internet and noting seems to work for me. I have checked my paths and size of the lmdb files are non-zero. But the problem still exists. I have no idea how to solve this issue.

Below is my file settings:

Did you get rid of that error? If so, can you elaborate ?

ashutosh3308 commented 7 years ago

Yes, I got rid of this error. The LMDB directories paths were not set correctly

anindyasarkarIITH commented 7 years ago

I am new to caffe and do not have good idea on LMDB. Can you please elaborate like what was the initial path in your code and what was the final path in your code. And also could please mention what are the contents in in the final path. Would be much happier if you could say how to generate LMDB file for ICDAR-13 dataset.
