> 当我运行示例 urban_driver/closed_loop_test-checkpoint.ipynb 时，出现一个错误，提示 'ReferenceError:weakly-referenced object no longer exists' 。我发现这种错误发生在 dict [int, EgoDataset] 的 deepcopy 函数中。有没有人有类似的错误？ [关于 deepcopy.txt 的错误](https://github.com/lyft/l5kit/files/7575980/bug.about.deepcopy.txt) I also encountered this problem, how did you solve it?
