I followed the instructions here to create a onefile flask-app deployed to apache2 with mod-wsgi on ubuntu. That all works fine when using the original flask app. However, when adding import nltk to the flask app apache hangs (no 500).
I use python 2.7 and nltk 2.0.4
Others seem to have had similar problems with other packages. Setting
WSGIApplicationGroup %{GLOBAL}
in the VirtualHost configuration seemed to have helped. However, I still get the same behavior. Did anybody run into the same issue? Thanks for the help!
Here is the VirtualHost Configuration file:
<VirtualHost *:8080># ---- Configure VirtualHost Defaults ----ServerAdmin [email protected] DocumentRoot /home/bitnami/public_html/http<Directory />Options FollowSymLinksAllowOverride None</Directory><Directory /home/bitnami/public_html/http/>Options Indexes FollowSymLinks MultiViewsAllowOverride NoneOrder allow,denyAllow from all</Directory># ---- Configure WSGI Listener(s) ----WSGIDaemonProcess flaskapp user=www-data group=www-data processes=1 threads=5WSGIScriptAlias /flasktest1 /home/bitnami/public_html/wsgi/flasktest1.wsgi <Directory /home/bitnami/public_html/http/flasktest1>WSGIProcessGroup flaskappWSGIApplicationGroup %{GLOBAL}Order deny,allowAllow from all</Directory># ---- Configure Logging ----ErrorLog /home/bitnami/public_html/logs/error.log

Here is the modified flask code
#!/usr/bin/python
from flask import Flaskimport nltk
app = Flask(__name__)
@app.route('/')
def home():return """<html><h2>Hello from Test Application 1</h2></html>"""@app.route('/<foo>')
def foo(foo):return """<html><h2>Test Application 1</2><h3>/%s</h3></html>""" % fooif __name__ == '__main__':"Are we in the __main__ scope? Start test server."app.run(host='0.0.0.0',port=5000,debug=True)
