Error related to avalanche.training.strategies

[mishma-akhtar]

I have to work on CRL for path generation of a drone. 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 you can see that the import is the following one: from avalanche.training.templates.base import BaseTemplate.
