Please wait a moment while I gather a list of all available modules...

/usr/lib/python3/dist-packages/IPython/kernel/__init__.py:12: ShimWarning: The `IPython.kernel` package has been deprecated since IPython 4.0.You should import from ipykernel or jupyter_client instead.
  warn("The `IPython.kernel` package has been deprecated since IPython 4.0."
Expected Tk Togl installation in /usr/lib/python3/dist-packages/OpenGL/Tk/togl-linux-64
Failure loading Togl package: can't find package Togl, on debian systems this is provided by `libtogl2`

Warnings should probably be suppressed during module importing in help. Any warnings emitted here are probably deprecation warnings or system configuration issues, not useful to a user trying to browse modules.
