Describe the Question

运行pycorrector/macbert/train.py时，报错。pytorch-lightning 版本2.0.4 。 不想降低pytorch-lightning 版本，该如何解决该问题。谢谢！

详细报错信息如下：

NotImplementedError: Support for `validation_epoch_end` has been removed in v2.0.0. `MacBert4Csc` implements this method. You can use the `on_validation_epoch_end` hook instead. To access outputs, save them in-memory as instance attributes. You can find migration examples in https://github.com/Lightning-AI/lightning/pull/16520.

你不想降低pytorch-lightning 版本，我不知道了。
