(from distilbart issue).

Hey @sshleifer , thanks for the distilled BART version I was able to fine tune it with the same script on BillSum dataset as T5 but the numbers are way different between the two. I just wanted to understand if I might be doing something wrong with regards to fine tuning distilBART, does it require student training everytime?
Reference numbers on BillSum Dataset:

T5-base:
avg_train_loss = tensor(1.5333, device='cuda:0')
avg_val_loss = tensor(1.4528, device='cuda:0')
epoch = 1
loss = tensor(1.6734, device='cuda:0')
rouge1 = 0.49188267841912325
rouge2 = 0.26436589848185027
rougeL = 0.3591894400892483
train_loss = tensor(1.6734, device='cuda:0')
val_loss = tensor(1.4528, device='cuda:0')

dBART-cnn-12-6:
avg_train_loss = tensor(1.3013, device='cuda:0')
avg_val_loss = tensor(1.4013, device='cuda:0')
epoch = 1
loss = tensor(1.4901, device='cuda:0')
rouge1 = 0.3681518923769047
rouge2 = 0.15683286277623087
rougeL = 0.23453727441540043
train_loss = tensor(1.4901, device='cuda:0')
val_loss = tensor(1.4013, device='cuda:0')

PS. I am using a modified version of the older finetune.py so it doesn't have Rouge for validation epochs.

Thanks

Interesting! 
I wonder what you get starting from bart-large. 
If you use the new finetune.py with --logger wandb I could more easily see your logs and suggest hyperparameters.


Thanks! and Sure, let me do that and share the results soon!

Took me a while to get to this :/ the numbers look as expected when fine-tuned with the latest finetune.py! :)
Must have been a bug in my modified script, updated that too and confirmed the results:
dBART:
"val_avg_loss": 1.3925694227218628,
"val_avg_loss": 1.3925694227218628,
"val_avg_rouge1": 0.576209431885421,
"val_avg_rouge2": 0.34462863342832595,
"val_avg_rougeL": 0.3999874418853423,
"val_avg_gen_time": 6.152730942964554,
"val_avg_summ_len": 132.768        

T5:
"val_avg_loss": 1.6064366102218628,
"val_avg_rouge1": 0.5291717003599621,
"val_avg_rouge2": 0.3049920551697407,
"val_avg_rougeL": 0.37437278542325914,
"val_avg_gen_time": 2.408391712649965,
"val_avg_summ_len": 171.18881856540085


Just a quick query though if you could help me out, for a lot of the predictions in the resulting test_generation file, I am getting summaries starting with lower case, and then generating a coherent summary from there on.
I looked at my dataset and the code and fine-tuned the models again after some pre-processing but still the same result.
Any ideas?? This was for both T5 and dBart btw.

Thanks! 


Can I see an example of an input, output pair that demonstrates the issue you are facing?

Here you go...apologies I should have shared the examples in the previous post itself :)
**Example 1:
Src :** This Act may be cited as the "Military Call-Up Relief Act". (a) Waiver For Certain Distributions. (1) In general. Section 72(t)(2) of the Internal Revenue Code of 1986 is amended by adding at the end the following: (G) Distributions to individuals performing national emergency active duty.

The amendments made by this subsection shall apply to contributions in taxable years ending after December 31, 2001.

**Ground Truth:**  Amend the internal revenue code of 1986 to provide a waiver of the early withdrawal penalty for distributions from qualified retirement plans to individuals called to active duty during the national emergency declared by the president on september 14, 2001, and for other purposes. Military Call-up Relief Act - Amends the Internal Revenue Code to waive the ten percent early withdrawal penalty for distributions from qualified retirement plans to individuals called to active duty during the national emergency declared by the President on September 14, 2001.

**Prediction:** military call-up relief act - Amends the Internal Revenue Code to allow a tax-exempt distribution to an individual who is a member of a reserve component called or ordered to active duty during the period of the national emergency declared by the President on September 14, 2001. Requires an employer plan to not be treated as failing for purposes of this Act. Provides for a catch-up contribution for certain distributions.

**Example 2:
Src:** This Act may be cited as the "National Climate Service Act of 2009". The Congress finds the following: (1) Weather, climate change, and climate variability affect public safety, environmental services and security, human health, agriculture, energy use, water resources, and other factors vital to national security and human welfare. (2) Climate forecasts create opportunities for society to prepare, potentially reducing the costs of climate-related events, as well as serving national needs related to enhancing economic growth, managing risk, protecting life and property, and promoting environmental stewardship. (3) Information on predicted climate and climate impacts is not being fully disseminated or used well, despite the increasing predictability of climate. (4) The United States lacks adequate research, infrastructure, and coordinated outreach and communication mechanisms to meet national climate monitoring, prediction, and decision support needs for adapting to and mitigating the impacts of climate change and climate variability. (5) Increasing societal resilience to climate impacts requires understanding climate trends and variations as well as possible, understanding the impacts of climate on human and nonhuman systems, providing decision-relevant tools based on that information, and increasing society's capacity to act on that information. It is the purpose of this Act to establish a National Climate Service that will assist the Nation and the world in understanding, anticipating, and responding to climate, climate change, and climate variability and their impacts and implications. The Service shall inform the public through the sustained production and delivery of authoritative, timely, useful information about impacts on local, State, regional, tribal, national, and global scales.

I encountered the similar with finetune with Fairseq version bart-large, https://github.com/pytorch/fairseq/issues/2347. Looks like it is a in complete sentence or starting from a middle of a sentence. 
It will be great if you shed some light on this.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.
