I highly reccomend to create a Python environment using virtualenv to install such versions
You must install all libraries in requriements.txt
Make sure ACE and ART are on path to the WSGI. Both binaries need to be in a place where WSGI can see it. In your own bin it will not work. I chose to put it in /usr/bin/ace and it works fine.
You need to start by installing some basics:
$ sudo apt-get update
$ sudo apt-get -y upgrade
$ sudo apt-get install -y python3-pip
$ sudo apt-get install build-essential libssl-dev libffi-dev python-dev
$ sudo apt-get install -y python3-dev python3-venv
$ sudo apt-get install virtualenv
$ sudo apt-get install subversion
$ sudo apt-get install python-nltk
Now you need to install the python dependencies. We will use requirements.txt for this:
$ cd ~/
$ mkdir environments
$ cd environments/
environments/$ virtualenv -p python3 itell_env
environments/$ source itell_env/bin/activate
(itell_env) environments/$ pip install -r /var/www/itell/requirements.txtMake sure you have the NLTK data available from a publicly visible location. For example:
sudo python -m nltk.downloader -d /usr/local/share/nltk_data wordnet
sudo python -m nltk.downloader -d /usr/local/share/nltk_data omw
sudo python -m nltk.downloader -d /usr/local/share/nltk_data punkt
sudo python -m nltk.downloader -d /usr/local/share/nltk_data cmudict
sudo python -m nltk.downloader -d /usr/local/share/nltk_data averaged_perceptron_taggerMake sure you have the grammars in place (app-folder/static/...).
First run:
/var/www/itell/delphin$ bash pull_update_erg2018.bash
/var/www/itell/delphin$ bash pull_update_ergTRUNK.bash
/var/www/itell/delphin$ bash pull_update_zhong.bashThen, for now, you need to compile and copy these grammars to /var/www/itell/static/ erg.dat erg-mal.dat zhong.dat
Build databases and basic data files: /var/www/itell/bin$ bash build_db.bash /var/www/itell/bin$ python dump_wn.py
Both the folders and content of [db\](db) and [delphin\](delphin) need to be accessible by 'www-data', with read, write and executing permissions.
The best way to do this is to change the group ownership of these folders to 'www-data'
Failing to do this will, among other things, show the access to dbs as "locked".
sudo chgrp -R www-data delphin/ sudo chgrp -R www-data db/
Copy something this into your apache2 config.

In the event you get errors such as: UnicodeEncodeError: 'ascii' codec can't encode character 'xxx' in position xxx: ordinal not in range(128)
This is likely due to the default enconding configs available to apache2, and that are possibly incomplete in your machine. To avoid these issues, ensure that the following lines are included in your apache envvars file (typically found in /etc/apache2/envvars).

export LC_ALL='en_US.UTF-8'
