It looks like you are almost there.
First, you are trying to print the MHImageHash object and not the
actual hash, the hash field would be hashes.hash.
The MVP tree must be created with at least leaf capacity + 3 images,
which by default is 28 I believe. Try placing 30 images in your
directory and then create the MVP tree.
Please keep us posted on your progress.
