I am getting the following error and I can not figure out why:
AttributeError: 'Trainer' object has no attribute 'training_type_plugin'

Could you share your optuna and pytorch-lightning versions?

Answer 3 · 2023-03-23T14:12:59.000Z

Could you share your optuna and pytorch-lightning versions?

optuna version : 3.1.0
pytorch_lightning version : 2.0.0

Thanks
Optuna doesn't support pytorch_lightning 2.0, as mentioned in optuna/optuna#4524. Could you use an older one? In addition, Optuna recently supports pytorch-lightning>1.5, which feature has not been released, so please use the master branch rather than 3.1.0.

Thank you for sharing the information.
Actually, PyTorchLightningPruningCallback work with pytorch_lightning==2.0 (See #179) on master branch, but the test fails since the mock class depends on deprecated features. Therefore, you can use pytorch_lightning==2.0 too if you used the master branch. Sorry for not updating the issue and make confusion.
