Use different lr for different policies

I’m using rllib under the MARL setting and need to set different lr for different policies. I’ve tried to set these in configs.multi_agent() as follows:

    policies = {
        "policy_0": (None, None, None, {"lr": 1e-4}), 
        "policy_1": (None, None, None, {"lr": 2e-4}), 

However, it seems like none of these works. The policies still use the lr set in

How can I do this right?
