Cannot reload saved work

[lmunnis]

I am running Vatic on Ubuntu 18.04 with python 2.7 using --offline. I was able to label a segment (ID=2) and save my work. Now, however, any time I try to reload the labeled segment (http://localhost/?id=2&hitId=offline), I'm getting the following in the apache error.log:

Not even sure why it's looking for numpy, since I traced this down to vatic/public/ui.js calling function ui_loadprevious --> vatic/public/server.py getboxesforjob(id). When I run server.py's getboxesforjob(id) locally, it works just fine, and doesn't even seem to use numpy.

Any help is much appreciated!

In case it helps anyone, for me this was caused by the "tuple" in getboxesforjob(id) somehow triggering numpy error (commented it out, ran fine, added it and it failed).

Numpy was installed in my home/userid/.local/lib/python2.7/site-packages directory with a+rx but the browser still wasn't seeing it - confirmed this by adding a "print sys.path" in getboxesforjob(id). So instead I put a symbolic link to my numpy directory in /usr/local/lib/python2.7/dist-packages, and then the labelled segment loaded with the previously drawn bounding boxes.

For good measure, I also added symlinks for pyscopg2 and scipy, since they were in the same place as numpy.

I think the morale of the story is to probably not install vatic in your home directory. Did see something from the mod_wsgi creator that said there may be problems being able to find things in the /home directory.
