QA task scores

There's no test set for QA, so the scores shown after the git PR would be on the same dev set, I believe. Since the dev set does have the labels we should have been able to use the f1 scores printed locally (which look okay ~72 for lr=5e-6, bs=2, epochs=16, max_seq=512, seed=32 ). I fail to understand why the scores retrieved via the pull request differ, being extremely poor ( ~ 25.3 )? Please let me know if there's anything I could be missing here or why this inconsistency?
PS: model is bert-base-multilingual-cased bert

Hi. Could you post a complete training log for QA somewhere and link it here. I need to have a look at it before I can say anything>

For QA there's a train set and a dev set. Evaluation is done on the dev set. The dev set seems to be provided with correct labels(and not just placeholders). So the f1 score on this set printed locally should've been the same as that rendered  through the PR. Following is the log when run for default params and uncommenting parts of code in run_squad.py that prints the results after evaluation.
bash train.sh bert-base-multilingual-cased bert QA_EN_HI
Fine-tuning bert-base-multilingual-cased on QA_EN_HI
06/25/2021 18:23:58 - WARNING - main -   Process rank: -1, device: cuda, n_gpu: 1, distributed training: False
Some weights of the model checkpoint at bert-base-multilingual-cased were not used when initializing BertForQuestionAnswering: ['cls.predictions.bias', 'cls.predictions.transform.dense.weight', 'cls.predictions.transform.dense.bias', 'cls.predictions.decoder.weight', 'cls.seq_relationship.weight', 'cls.seq_relationship.bias', 'cls.predictions.transform.LayerNorm.weight', 'cls.predictions.transform.LayerNorm.bias']

This IS expected if you are initializing BertForQuestionAnswering from the checkpoint of a model trained on another task or with another architecture (e.g. initializing a BertForSequenceClassification model from a BertForPreTraining model).
This IS NOT expected if you are initializing BertForQuestionAnswering from the checkpoint of a model that you expect to be exactly identical (initializing a BertForSequenceClassification model from a BertForSequenceClassification model).
Some weights of BertForQuestionAnswering were not initialized from the model checkpoint at bert-base-multilingual-cased and are newly initialized: ['qa_outputs.weight', 'qa_outputs.bias']
You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.

In dono payment System ko Reserve Bank of  India (RBI) manage karta hain. In dono payment system ke jariye sirf aap India ke andar hi paise send kar sakte hain. Aaiye jante hain dono mein kya difference hota hain. RTGS mein Funds turant hi transfer ho jate hain. Yeh different Bank ke beech mein fund transfer karne ka sabse fast medium hain. Rule yeh hain ki jis Bank ko paisa send kya gya hain usay receiver ke account mein 30 minutes ke andar paisa credit kar dena hota hain. Dusri aor NEFT ke tahat paise turant transfer nahi ho paate hain. Is System mein hours ke according time slot mein kaam hota hain. Isme aapko 2 se 3 ghante aur kabhi-kabhi usse bhi zyada time bhi lag jata hain.  Kya Bank account ka hona jaroori hain? Jinka Saving Account ya Current Account hain, Veh customer NEFT aur RTGS dono hi services ka use kar sakte hain. Lekin, jinke Bank account nahi hain, Veh sirf NEFT wali Branches mein cash deposit kar sakte hain. Halanki aap NEFT ke tahat 50,000 rupees se jyada Cash jama nahi karwa sakte hain.  Kab se kab tak hota hain transaction ? Aap RTGS ke tahat Morning 8 baje se shaam 4:30 Baje tak hi paise bhej sakte hain. Vah bhi jis din Bank open huye hote hain. Vahi, NEFT mein Subah 8 Baje se lekar shaam 7 Baje tak total 12 transfer kar sakte hain. Halanki, kai baar alag-alag Bank alag-alag time ka palan karte hain.  Online RTGS aap time table ke according hi kar sakte hain. Lekin online NEFT ke tahat agar Paisa time rahte nahi bheja gya toh saamne wale ko paisa Bank ke next working day par hi paisa milega.  Kitna Amount Send kar sakte hain? RTGS system ka use Big amount send karne ke liye hota hain. Isme minimum 2 Lakh aur Maximum 10 Lakh rupaye transfer kiye ja sakte hain. Vahi, NEFT mein aap jitna chahe utna paisa send kar sakte hain, Lekin yeh Sirf Online NEFT mein kar sakte hain, Offline yani ki Bank branch mein jakar Cash Deposit aap 50,000 se zyada nahi karwa karwa sakte hain.  Transaction agar Fail ho jaye toh ? RTGS ke tahat agar money send karne par agar paisa paane wale ke account mein paise jama nahi ho paye toh vah paisa automatically aapke Bank account mein dubara vaapis aa jata hain. Vahi NEFT transaction fail hone par Jis bank mein aapne paise bheje hain usay 2 hours ke andar aapke bank ko paise vaapis karne hote hain.  Charges kya hain ? Every NEFT transaction ke liye Services Tax ko chhod kar 25 Rupees se jyada charge nahi liya jayega. Vahi RTGS mein maximum fee 55 rupees hain. Aap Bank ke kisi bhi branch se transfer karne ke mukable Online Transaction karna zyada faydemand hota hain.  Kya transaction ko roka ja sakta hain? Yunki RTGS mein Real time transaction hota hain, isliye agar aapne transaction kar diya hain toh usay baad mein bhi rok sakte hain. Vahi, NEFT mein bhi aisa hi hota hain."}]}, {"title": 9, "paragraphs": [{"qas": [{"question": "Mitashi ke Android TV me RAM kitna hai?", "id": 9, "answers": [{"text": "512 MB", "answer_start": 649}], "is_impossible": false}], "context": "Mitashi ne ek Android Tv ko Launch kiya hain.

Airtel hi pahli company hain jisne 2012 mein Kolkata mein "Broadband Wireless Access" ke liye pahli 4G Service shuru ki thi. Is company ne February 2014 mein Bengaluru mein pahli baar 4G sewa shuru ki thi. August 2014 tak ek aur operator Aircel ne 6 States mein 4G Broadband sewa shuru ki, Lekin yeh gair mobile sewa thi.5. Kya yeh mehnga padega ?Halaki Airtel ne 4G ka rate 3G ke barabar hi rakha hain, Lekin aap jyada kharch kar sakte hain. Isme Data jyada tezi se istemal hota hain. Aap 4G mein jyada Video dekh sakte hain. Yeh 3G ke mukable yeh jyada behtar quality ke hote hain aur asaani se chalte hain. Aap Whatsapp aur Email par jyada tezi se pictures download ya upload kar sakte hain. 6. Mere shahar mein kya yeh kaam karega ?Mumbai aur Gurgaon jaise kai big aur busy cities mein coverage ek jaise nahi hota hain. Kai jagaho par toh Jaroori mobile tower bhi nahi hain. Delhi mein Municipal Corporation ne bahut saare tower hata diye hain. Vaha kuch jagah mobile coverage bahut gadbad ho gyi hain aur lagatar call drops hoti hain. Par yeh problem 4G tak hi simit nahi hain.7. Kya behtar offer ka wait karna chahiye ?Ise lene ka yahi accha samay hain. Airtel 4G users ko kai gift bhi de rahi hain, jaise Unlimited Voice calls, Movies aur Music. Iske alawa iske Wynk mobile app par aap 25,000 movies aur 18 Lakh songs stream kar sakte hain. Iske liye aap Airtel ne Flipkart ke samjhauta kiya hain, Agar aap Flipkart se Koi bhi 4G smartphone khareedte hain to Airtel ka 4G Sim saath mein milta hain.8. Bharat ki tarah ka 4G istemal karta hain ?Bharat LTE naam ki technique ka istemal karta hain jo ki 4G ke liye 2300 MHz Frequency Spectrum par kaam karta hain. LTE pahli baar 2009 mein Europe mein istemal ki gyi thi. Ek aur technique WiMax bahut acchi tarah se nahi chali aur ab kuch ki countries mein iske istemal kiya ja raha hain.9. Kaun-Kaun si companies 4G service shuru kar rahi hain?Mukesh Ambani ki Reliance Geo December 2015 mein 4G service zor-shor se shuru karne ka plan bana rahi hain. Isne 5 years mein Gadgets aur tower install karne ke liye 14 Arab Doller yani ki takreeban 9.20 Kharb rupaye se jyada kharch kiye hain. Dusri aor Airtel ne pichle 20 saal mein gadgets par 15 Arab Dollar yani ki 9.86 Kharab rupaye se jyada kharch kiye hain. Iske alawa isi financial year mein Vodafone aur Idea bhi apne 4G service shuru karenge.10. Paisa bachane ka sabse accha tarika kya hain?Chunki 4G bahut tez hain, Isliye aapko lalach hota hain ki aap jyada pictures aur video download kar le. Isse bachna hi theek rahega. Example ke liye Whatsapp par "Auto Download Media" ka option ko Mobile data par band karke rakhna chahiye. Iske saath hi "Mobile Data Roaming" setting ko bhi off rakhe.Iske saath hi koshish kare ki jab bhi possible ho to pictures aur Video download karne ke liye Wi-Fi ka istemal kare."}]}, {"title": 137, "paragraphs": [{"qas": [{"question": "Microsoft ke naye browser ka naam kya hai?", "id": 137, "answers": [{"text": "Microsoft Edge", "answer_start": 280}, {"text": "Microsoft Edge", "answer_start": 554}, {"text": "Microsoft Edge", "answer_start": 1007}], "is_impossible": false}], "context": "Internet Explorer ko alvida kahne ka waqt ab aa gya hain.

Please let me know if this is the processed dev set .

Could you upload it some filesharing site or some site like pastebin?

The file that I have on my end does not have questions with ID 235 onwards in the dev set. Could you make a backup of the dev file, delete the keys with ID 235 onwards and try running training again? It looks like the higher score you are getting is due to these extra questions being considered as part of the dev set

Here's the dev set I had been using: Data/Processed_Data/QA_EN_HI/dev-v2.0.json. Even after removing the titles with ids 235 onwards, the inconsistency persists. Local dev set F1 score is ~67 while the PR gives around 24 !

I will check and get back. When you updated the dev file, did you delete the cache file in the same directory? If not, please delete that file and try re-running.

Also tried after deleting the cached dev file, that didn't help either.

It seems that the QA dataset processing scripts are returning more data points in your case than what is actually expected.
I would suggest that you please try to rerun the QA preprocessing alone in a new python:3.6 docker container and check the dataset that you obtain. Please check if the train set has 259 entries and the test has 54 entries.

I've been getting 313 entries in train and 70 in dev set.

I seem to have figured out what the issue is. Would you be able to try running the code again with a few changes?
When you're running the docker container, use this exact image -  python:3.6.10. Also, apply this patch to the GLUECoS repo. It changes 2 lines in the Data/Preprocess_scripts/preprocess_qa.sh file.

I will update the scripts and the readme with these additional instructions. Were you able to submit and run evaluation properly?

Yes, the score on submission is consistent  now. Thanks again.
