Crash when using `SelectEntityAction` #6

Open cswinter opened 2 years ago

cswinter commented 2 years ago

Occasionally, the PickMatchingBalls environments runs into the following error:

Currently running into the same bug. The action is a selection of a list of flows.

observation = envs.act(data[0], data[1])

This error happens if the entity list of the actees is empty. A better error message would help in debugging.
