loss = 0 after first log with trainer API

[SunMarc]

Hi @not-lain, that's probably not a bug. The dataset have only 200 rows. Could you try with a bigger dataset ?

[not-lain]

Hi @SunMarc I have tried with both not-lain/docci and not-lain/docci-small , and the same behavior persisted after the first log

[not-lain]

@SunMarc after some fiddling It seems that this is not related to the trainer API rather to my training script

• before
  
• after applying

model.text_model.train()
model.config.use_cache = False
model.text_model.transformer.gradient_checkpointing_enable()
torch.autograd.set_detect_anomaly(True)
