Trying to test out ocropus from sources

[crazylyle]

Trying to just try out OCRopus on some files that tesseract fails (badly) on.

I download the zip file from github, and expand it into /tmp/ocropus.
Then following README.md,

1. I make sure all the packages in PACKAGES are installed. This is a
   Fedora 30 system, so it uses dnf, not apt-get, but all the packages
   are there.

2. I use wget to get
   83826134 Nov 2 2014 en-default.pyrnn.gz

3. I then try to move to models/:

/tmp/ocropus > mv en-default.pyrnn.gz models/
mv: cannot move 'en-default.pyrnn.gz' to 'models/': Not a directory

so to correct this, I:
/tmp/ocropus > mkdir models
models created
/tmp/ocropus > mv en-default.pyrnn.gz models/
/tmp/ocropus > ls models
83826134 en-default.pyrnn.gz

4. I don't want to install in /usr/bin, since I just want to try it,
   but let's let is go to see what happens:

python setup.py install
running install
running build
running build_py
error: package directory 'ocrolib' does not exist

5. Another missing directory, so mkdir ocrolib, and try again

Now we get, in a much longer set of messages:

package init file 'ocrolib/init.py' not found (or not a regular file)
...

warning: install_lib: 'build/lib' does not exist -- no Python modules to install

and finally:

copying build/scripts-2.7/ocropus-gated-train -> /usr/bin
error: [Errno 13] Permission denied: '/usr/bin/ocropus-gated-train'

Now trying to test,

/tmp/ocropus > ./run-test
Traceback (most recent call last):
File "./ocropus-nlbin", line 15, in
import ocrolib
ImportError: No module named ocrolib

but we have a directory ocrolib/, but it is empty.
