Project environment variables
=============================

Some Python packages depend on environment variables for correct operation. For 
example, Theano requires the directory containing the CUDA compiler to be 
included in the ``$PATH`` environment variable for GPU acceleration to be 
enabled.

To change environment variables for all AEN apps, modify the project runtime 
configuration file ``.projectrc`` as described on 
the :doc:`compute-resource-config` page.

This file is sourced when a user opens any AEN app. This includes the Jupyter 
app, and Jupyter kernels will be able to read these environment variables.

``.projectrc`` sets several AEN internal environment variables and sets up the 
project environment, and can set additional user environment variables for that 
project.
