Environment Variables ===================== If running Composapy in a DataLab, your environment variables will already be set up on your running instance. If running outside of a DataLab instance, you will need to set "DATALAB_DLL_DIR". "APPLICATION_URI" can also optionally be set, however it is only used to create a Session object and can be passed in as the "uri" argument. DATALAB_DLL_DIR --------------- The value of this should be a path to the required Composable dll's needed to run Composapy. Composapy uses the `PythonNet `_ package to bind to the Composable project dll's. APPLICATION_URI --------------- See :doc:`/reference/composapy-session`. COMPOSAPY_INI_DIR ----------------- This can be set to change the read/write location of the "composapy.ini" configuration file. If not specified, defaults to current working directory.
