Universal NLU/NLI Dataset Processing Framework

It is designed with BERT in mind and currently support seven commonsense reasoning datsets(alphanli, hellaswag, physicaliqa, socialiqa, codah, cosmosqa, and commonsenseqa). It can be also applied to other datasets with few line of codes. It adopts pandas and modin[ray]'s multiprocessing in loading/processing the datasets.

Architecture

Dependency

pip install -r requirements.txt

Download raw datasets

./fetch.sh

It downloads alphanli, hellaswag, physicaliqa, socialiqa, codah, cosmosqa, and commonsenseqa from AWS in data_cache. In case you want to use something-something, pelase download the dataset from 20bn's website.

Usage

Following examples show how to load a dataset or create a multitask dataset from multiple datasets.

Load a dataset in parallel with modin[ray]

from transformers import BertTokenizer
from textbook import *
import modin.pandas as pd

tokenizer = BertTokenizer.from_pretrained('bert-base-cased')

d1 = MultiModalDataset(
    df=pd.read_json("data_cache/alphanli/train.jsonl", lines=True),
    template=lambda x: template_anli(x, LABEL2INT['anli']),
    renderers=[lambda x: renderer_text(x[0], tokenizer)],
    parallel=True
)
bt1 = BatchTool(tokenizer, source="anli")
i1 = DataLoader(d1, batch_sampler=TokenBasedSampler(d1, batch_size=64), collate_fn=bt1.collate_fn)

Load a dataset with naive pandas

from transformers import BertTokenizer
from textbook import *
import pandas as pd

tokenizer = BertTokenizer.from_pretrained('bert-base-cased')

d1 = MultiModalDataset(
    df=pd.read_json("data_cache/alphanli/train.jsonl", lines=True),
    template=lambda x: template_anli(x, LABEL2INT['anli']),
    renderers=[lambda x: renderer_text(x, tokenizer)],
    parallel=False
)
bt1 = BatchTool(tokenizer, source="anli")
i1 = DataLoader(d1, batch_sampler=TokenBasedSampler(d1, batch_size=64), collate_fn=bt1.collate_fn)

Create a multitask dataset with multiple datasets

from transformers import BertTokenizer
from textbook import *
import pandas as pd

tokenizer = BertTokenizer.from_pretrained('bert-base-cased')

# add additional tokens for each task as special `cls_token`
tokenizer.add_special_tokens({"additional_special_tokens": [
        "[ANLI]", "[HELLASWAG]"
]})

d1 = MultiModalDataset(
    df=pd.read_json("data_cache/alphanli/train.jsonl", lines=True),
    template=lambda x: template_anli(x, LABEL2INT['anli']),
    renderers=[lambda x: renderer_text(x, tokenizer, "[ANLI]")],
    parallel=False
)
bt1 = BatchTool(tokenizer, source="anli")
i1 = DataLoader(d1, batch_sampler=TokenBasedSampler(d1, batch_size=64), collate_fn=bt1.collate_fn)

d2 = MultiModalDataset(
        df=pd.read_json("data_cache/hellaswag/train.jsonl", lines=True),
        template=lambda x: template_hellaswag(x, LABEL2INT['hellaswag']),
        renderers=[lambda x: renderer_text(x, tokenizer, "[HELLASWAG]")],
        parallel=False
    )
bt2 = BatchTool(tokenizer, source="hellaswag")
i2 = DataLoader(d2, batch_sampler=TokenBasedSampler(d1, batch_size=64), collate_fn=bt2.collate_fn)

d = MultiTaskDataset([i1, i2], shuffle=False)

#! batch size must be 1 for multitaskdataset, because we already batched in each sub dataset.
for batch in DataLoader(d, batch_size=1, collate_fn=BatchTool.uncollate_fn):

    pass

    # {
    #     "source": "anli" or "hellaswag",
    #     "labels": ...,
    #     "input_ids": ...,
    #     "attentions": ...,
    #     "token_type_ids": ...,
    #     "images": ...,
    # }
