What does "pip install ray[debug]" do?

In the installation docs here it gives the following option to install ray:

pip install -U ray  # also recommended: ray[debug]

I am curious what pip install -U 'ray[debug]' does that pip install -U ray does not. Looking at the setup.py, it doesn’t seem like the debug option adds anything. Can you help me understand the difference? Thanks.

Good catch, the docs should be updated to remove that suggestion as it currently does not do anything.

If you’re interested in submitting a patch, that would be very welcome :slight_smile:

No problem. It is posted here. The format requests that I add a reviewer but that didn’t seem possible. Let me know if there is something I am missing.
