    RuntimeError: The size of tensor a (3) must match the size of tensor b (15) at non-singleton dimension 1
    ^ in cmd promt not editor, as the very last message as it abruptly stops

    This error started occuring after I set observation stacks to 5 for the camera sensor of my agent.
    The training is fine for aproximately 10k steps before this error occurs and it exports the results and shuts down.
    Does anyone know what's going on here?

    [Solved] I initialized from a new run-id, and although I'm unsure if this helped too, but I made "observable attribute handling" in behavior parameters to examine all.
