我正在 运行 在一个新的远程服务器上安装一个代码，该代码曾经在另一个远程服务器上工作。我想我以同样的方式设置了东西，但是当我 运行 我的训练脚本时，我得到这个错误：
Traceback (most recent call last):

ValueError: Expected a parent
由于某些原因，这部分代码看起来有问题：
model = get_model(mname=mname)
dm = DataModule(
X_train=X_train,
y_train=y_train,
X_val=X_val,
y_val=y_val,
X_test=X_test,
y_test=y_test,
keys_train=keys_train,
keys_val=keys_val,
keys_test=keys_test,
seq_len=seq_len,
batch_size=batch_size,
num_workers=4
)
# trainer.logger_connector.callback_metrics
trainer.fit(model, datamodule=dm)
是不是和环境设置有关？某事被某事覆盖了？？
有人能给我指出正确的方向吗？
编辑：我试图在新创建的环境中 运行 我的本地项目，但我遇到了同样的错误。
编辑 2：我的 DataModule 继承自 LightningDataModule
class DataModule(pl.LightningDataModule):
问题是模型继承自 nn.Module 而不是 pl.LightningModule
