-               for environments that have a fixed episode length.
-
-            - "log" (dict[str, float | torch.Tensor]): Additional information for logging and debugging purposes.
-               The key should be a string and start with "/" for namespacing. The value can be a scalar or a
-               tensor. If it is a tensor, the mean of the tensor is used for logging.
