Text Classification Benchmark based-on Fine-tuned Transformer

1. Quick Start

# clone the project 
git clone [email protected]:celsofranssa/TeCBench.git

# change directory to project folder
cd TeCBench/

# Create a new virtual environment by choosing a Python interpreter 
# and making a ./venv directory to hold it:
virtualenv -p python3 ./venv

# activate the virtual environment using a shell-specific command:
source ./venv/bin/activate

# install dependecies
pip install -r requirements.txt

# setting python path
export PYTHONPATH=$PATHONPATH:<path-to-project-dir>/TeCBench/

# (if you need) to exit virtualenv later:
deactivate

2. Datasets

Downloading the datasets from Kaggle Datasets (get kaggle credentials on Kaggle API Docs):

kaggle datasets download \
  celsofranssa/tecbench-datasets \
  -p resource/dataset/ \
  --unzip

Make sure that after completing the download of the datasets the file structure is as follows:

3. Test Run

The following bash command fits the BERT model over 20NG dataset using batch_size=128 and a single epoch.

python main.py tasks=[fit] \
    model=BERT \
    data=20NG \ 
    data.batch_size=32 \ 
    trainer.max_epochs=1

If all goes well the following output should be produced:
