在data_interface中建立一个class DInterface(pl.LightningDataModule):用作所有数据集文件的接口。__init__()函数中import相应Dataset类,setup()进行实例化,并老老实实加入所需要的的train_dataloader,val_dataloader,test_dataloader函数。这些函数往往都是相似的,可以用几个输入args控制不同的部分。 同理,在model_...

然而,在上述循环中,通过 trainer.test 每执行一次测试,都只是执行了一个 epoch 的测试(也就是执行多次 ptl_module.test_step 和一次 ptl_module.test_epoch_end ),而不可能把 ckpt_list 中的多个预训练模型( checkpoint )当做多个 epoch ,多次执行 ptl_module.test_epoch_end 。我们期望,...
