Out-of-directory calls

[AngelAquino]

Hello, and thanks for making this parser available!

I wrote a shell script which calls predict.py from an external directory, but I encounter the following error:

Traceback (most recent call last):

The program works fine when called from within the udify directory itself, though. Would it be possible to modify the addresses in the source code to work for external calls as well? I'd be willing to help sift through the source files for this if needed.

The code assumes all paths point inside the repo for simplicity. One easy workaround is to create a symlink inside the repo that points to your desired directory/file. Otherwise, it should require some code changes to the scripts to get it working, probably not too difficult. I don't have time right now to look into this myself but I welcome pull requests.
