Description
Bug description
Testing from a given checkpoint leads to logging the epoch number of the last checkpoint instead of the checkpoint specified:
trainer = Trainer(..., max_epochs=10)
lightning_module = MyLightningModule(...)
datamodule = MyDatamodule()
trainer.fit(lightning_module , datamodule=datamodule)
trainer.test(lightning_module , datamodule=datamodule, ckpt_path="last") # <-- ok: logs correct epoch and step
ckpt_path="/.../checkpoints/epoch=2-step=396.ckpt"
trainer.test(lightning_module , datamodule=datamodule, ckpt_path=ckpt_path) # <-- incorrect: logs last epoch and step
The second test logs epoch 10 instead of epoch 2. Similarly, the step number of the second test is incorrect.
