Project environment variables (AEN 4.1.2)
=========================================

.. raw:: html

    <p>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 <code class="docutils literal"><span class="pre">$PATH</span></code> environment variable for GPU acceleration to be
    enabled.</p>
    <p>To change environment variables for all AEN apps, modify the project runtime
    configuration file <code class="docutils literal"><span class="pre">.projectrc</span></code> as described on
    the <a class="reference internal" href="compute-resource-config.html"><span class="doc">Compute Resource Config Application</span></a> page.</p>
    <p>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.</p>
    <p><code class="docutils literal"><span class="pre">.projectrc</span></code> sets several AEN internal environment variables and sets up the
    project environment, and can set additional user environment variables for that
    project.</p>
