Ok, perfect thanks!

Dear @ashivani, could you help me solve the issue as well or share the solution?

Hi @shravan.koninti, I’m having the exact same error of “Operation not permitted” when copying the assets directory, have you solved it by any chance?

Many thanks,

Flatland Challenge

RLLib config for Round 2

Over 4 years ago

Hi everybody,

I’m trying to configure RLLib https://github.com/ray-project/ray/tree/master/rllib with Flatland 2.1.8 for Round 2, starting from the code that was available in the baselines for Round 1, but I’m getting the following errors:

TypeError: can’t pickle _thread.lock objects

And using Tune:
TypeError: Object of type ‘TreeObsForRailEnv’ is not JSON serializable

This happens both using ray version 0.7.0 (as suggested in the old README) and the latest ray 0.7.6.
Someone that managed to configure RLLib with Flatland could give me some advice about that?

Thanks in advance!

Communication among agents

Over 4 years ago

Hi,
is communication among agents possible in this challenge in a multi-agent setup? Or can we expect that in a future version of Flatland?

Best,
Giulia
