After obtaining a Spark environment, you can view the exact packages installed in the Spark environment in the Resolved Dependencies dialog. To open the dialog, select Environment > View resolved packages. The dialog will show a list of the direct and transitive dependencies.
A direct dependency is a package explicitly specified by the user to include in the Spark environment. You can specify direct dependencies in the Customize Spark Environment menu.
A transitive dependency is a package relied upon by a direct dependency. For example, depending on statsmodels transitively imports NumPy, SciPy, MatPlotLib, and their dependencies as well.
