Using environment variables (AEN 4.1.3)
=======================================

.. raw:: html

    <p>Some Python packages depend on environment variables for correct operation.</p>
    <p>EXAMPLE: Theano requires that the directory containing the CUDA compiler is
    included in the $PATH environment variable in order for GPU acceleration to be
    enabled.</p>
    <p>To change environment variables for all AEN applications, modify the project
    runtime configuration file <code class="docutils literal"><span class="pre">.projectrc</span></code>. For more information, see
    <a class="reference internal" href="../basic-tasks/apps/use-crc.html"><span class="doc">Using Compute Resource Configuration</span></a>.</p>
    <p><code class="docutils literal"><span class="pre">.projectrc</span></code> sets several AEN internal environment variables, sets up the
    project environment and can set additional user environment variables for that
    project. This file is sourced when a user opens any AEN application&#8212;including
    Jupyter Notebook&#8212;and Jupyter kernels will be able to read the included
    environment variables.</p>
