(ITS#8467) LMDB creation

I've been trying to create LMDB files for a particle physics project in
classifying particle interactions. Anyways, I modified an old code used to
create levelDB files from a TTree in the Root software developed by CERN using
c++. Then, I tried to run the neural net on the lmdb files and it gave me an
error that std::string_length was too large. And I tried to show the images I
had saved in it and it didn't show me anything, whereas on an LMDB file I had
from one of the caffe tutorials it did show me the image.

Do you have any ideas of what could be wrong? It think it is likely that I
messed something up and can't find a lot of documentation for building LMDB
files. In addition, I'm fairly new to coding and I had a hard time reading the
API page due to this. If you have any ideas of how to help that would be great.
