For learning, I tried to run 'simple_dqn.py' from this repository but it shows error related to avalanche training strategies. I am using version avalanche version 0.3.1 and pyhton 3.9
Are you sure that you are using the latest version of Avalanche-RL? Because in the error the code is trying to import `BaseStrategy` which was in the old version of Avalanche and Avalanche-RL. Recently we fixed these errors aligning the two libraires and one of the changes was removing `BaseStrategy` and move to `BaseTemplate`. In fact, if you check the current version of [`metrics_definition.py`](https://github.com/ContinualAI/avalanche-rl/blob/master/avalanche_rl/evaluation/metric_definitions.py) you can see that the import is the following one: `from avalanche.training.templates.base import BaseTemplate`.
