Have tested this algorithm again just now, you are correct that it misidentifies the case you suggest as having no disconnected substations:  For the next attempts I will proceed...

Not sure, we are currently using it to check whether a maintenance action is safe. Since it only works for power line status changes (won't generalize to substation topology changes)...

From looking at the [Python Package documentation](https://python-packaging.readthedocs.io/en/latest/dependencies.html), there appears to be a small error in the setup.py file for Cortex where they use a dictionary {} instead of a list...

For now, as suggested by the BackEnd eerror when you try to disconnect a generator or a load, my workaround is to set the load and generation chronics to 0...

Have encountered a similar issue when processing the GRIB data from the [CERRA](https://cds.climate.copernicus.eu/datasets/reanalysis-cerra-single-levels?tab=overview) which is in a Lambert Conformal projection.

The runner in Grid2Op clearly does work and supports parallel processing so I looked inside of it, it does not use Grid2op.make but instead initializes the environment using init_obj_from_kwargs(...): Line...

Thank you Benjamin, I did not realize threading in Python was fundamentally difficult to do because of the Global Interpreter Lock. I usually opt for the multiprocessing library as well...

While the minimal example with the ThreadpoolExecutor you shared does work on my Windows machine, unfortunately it does not seem I can adapt it to work in Optuna. I don't...

Closing as this has been supplanted by PR #[661](https://github.com/Grid2op/grid2op/pull/661)

Ignore the bug label, as this is more of a question
