ModuleNotFoundError: No module named 'pytorch_lightning.metrics'

回答: 当出现ModuleNotFoundError: No module named 'pytorch_lightning.metrics'的错误时，这说明你的电脑上没有安装pytorch_lightning.metrics模块。\[3\]这个模块已经不再使用，如果你需要使用Accuracy、Precision、Recall、F1Score等功能，你可以使用torchmetrics模块来代替。\[2\]你可以通过以下命令安装torchmetrics模块：pip install torchmetrics。这样就可以在你的代码中使用torchmetrics的功能了。
