Docker network error when running `uv run python run_swelancer.py`

[0xluffyb]

1. I had to update my default address pool for Docker in order and make sure that there are enough subnets for the LocalClusters

RuntimeError: Too many docker networks have been created. Most machines/laptops default to allowing
16 LocalCluster instances.

2. Running uv run python run_swelancer.py after gives after network related error like:

Could you try lowering your concurrency below 16, and seeing if that helps?

[0xluffyb]

@leon-openai i think that would help the Too many docker networks created but putting concurrency = 1 still gives me this error:

TypeError: StopIteration interacts badly with generators and cannot be raised into a Future

[leon-openai]

Based on the error they're getting, if they're trying to run everything they should check out our documentation about Running at Scale! Our guidance to folks trying to run SWELancer is to check out the README first and then reach out for support.

Here's the writeup to running at scale, if helpful

[dchichkov]

The issue is that nanoeval is initializing all the dockers upfront, during the init. And the concurrency is not used during the init. The relevant code is in the project/alcatraz/alcatraz/clusters/local.py.

I've tried to reconfigure/change that (to either reuse networks or to create containers lazily), but the code is heavy on asyncio/ relatively difficult to debug, its not a trivial change.
