Error on prediction

[tobybatch]

The server is running in the new docker (https://github.com/neontribe/AG) but when I hit the prediction end point I get this error:

AttributeError: 'WordNetCorpusReader' object has no attribute '_LazyCorpusLoader__args'

I'm hitting the endpoint:

http://192.168.21.237:9091/predict?threshold=low&chunk=true&roll_up=true&text=To%20grow%20apple%20trees.%20To%20raise%20mussels%20and%20clams

The full error is here: https://gist.github.com/tobybatch/205bdf3481954c2345a9f6b3c09ef3ec

This is a known issue. The first request to the python Flask server results in this error. All subsequent requests will be handled normally and predictions will be returned.

One possible work-around is to add a startup script to server.py that primes the endpoint by running a dummy request to clear out this error. A full diagnosis will take some deeper investigative work.

I will leave this ticket open while we try to find a full solution, but in the meantime the server should function normally after the first request and you can try the suggested work-around.
