Basics

Resources

create a folder named "resources" and put the following resources here Stanford CoreNLP

NRC Emotion Lexicon v0.2: we use NRC-Emotion-Lexicon-Wordlevel-v0.2.txt and rename it as NRC-Emotion-Lexicon.txt

Spanish Hashtag Lexicon

Environment

create a virtual environment

conda create -n emo_env python=3.9.16

install packages via conda first and then via pip

conda install -c "nvidia/label/cuda-11.8.0" cuda-toolkit
conda install -c anaconda cudnn
conda install pytorch torchvision pytorch-cuda=11.8 -c pytorch -c nvidia
conda install openjdk=8
pip install -r requirements.txt

rename .env.example as .env and change the variable values in the file

Multirun

Do grid search over different configs.

python main.py -m \
    dataset=se_english \
    seed=0,1,2,3,4,5 \

Evaluate checkpoint

This command evaluates a checkpoint on the train, dev, and test sets.

python main.py \
    training=evaluate \
    training.ckpt_path=/path/to/ckpt \
    training.eval_splits=train,dev,test \

Finetune checkpoint

python main.py \
    training=evaluate \
    training.ckpt_path=/path/to/ckpt \

Offline Mode

In offline mode, results are not logged to Neptune.

python main.py logger.offline=True

Debug Mode

In debug mode, results are not logged to Neptune, and we only train/evaluate for limited number of batches and/or epochs.

python main.py debug=True

Hydra Working Directory

Hydra will change the working directory to the path specified in configs/hydra/default.yaml. Therefore, if you save a file to the path './file.txt', it will actually save the file to somewhere like logs/runs/xxxx/file.txt. This is helpful when you want to version control your saved files, but not if you want to save to a global directory. There are two methods to get the "actual" working directory:

1. Use hydra.utils.get_original_cwd function call
2. Use cfg.work_dir. To use this in the config, can do something like "${data_dir}/${.dataset}/${model.arch}/"

Config Key

• work_dir current working directory (where src/ is)

• data_dir where data folder is

• log_dir where log folder is (runs & multirun)

• root_dir where the saved ckpt & hydra config are

---

Example Commands

Here, we assume the following:

• The data_dir is data, which means data_dir=${work_dir}/../data.
• The dataset is semEval 2018 task 1-english.

1. Build dataset

The commands below are used to build pre-processed datasets, saved as pickle files. The model architecture is specified so that we can use the correct tokenizer for pre-processing. Remember to put a xxx.yaml file in the configs/dataset folder for the dataset you want to build.

python scripts/build_dataset.py --data_dir data \
    --dataset se_english --arch bert-base-uncased --split train

python scripts/build_dataset.py --data_dir data \
    --dataset se_english --arch bert-base-uncased --split dev

python scripts/build_dataset.py --data_dir data \
    --dataset se_english --arch bert-base-uncased --split test

If the dataset is very large, you have the option to subsample part of the dataset for smaller-scale experiements. For example, in the command below, we build a train set with only 1000 train examples (sampled with seed 0).

python scripts/build_dataset.py --data_dir data \
    --dataset se_english --arch bert-base-uncased --split train \
    --num_samples 1000 --seed 0

2. Train Multi-EmoBERT

The command below is the most basic way to run main.py

python main.py -m \
    data=se_english \
    model=lm \
    model.optimizer.lr=2e-5 \
    setup.train_batch_size=32 \
    setup.accumulate_grad_batches=1 \
    setup.eff_train_batch_size=32 \
    setup.eval_batch_size=32 \
    setup.num_workers=3 \
    seed=0,1,2

3. Train Model with Hashtag Encoding, Sentiment Composition and Emotion Correlation

This repo implements a number of different methods for training the Task LM. Below are commands for running each method.

Task LM + Hashtag Encoding

python main.py -m \
    data=se_english \
    model=lm \
    model.use_hashtag=True \
    model.hashtag_emb_dim=80 \
    model.optimizer.lr=2e-5 \
    setup.train_batch_size=32 \
    setup.accumulate_grad_batches=1 \
    setup.eff_train_batch_size=32 \
    setup.eval_batch_size=32 \
    setup.num_workers=3 \
    seed=0,1,2

Task LM + Sentiment Composition

python main.py -m \
    data=se_english \
    model=lm \
    model.use_senti_tree=True \
    model.phrase_emb_dim=80 \
    model.optimizer.lr=2e-5 \
    setup.train_batch_size=32 \
    setup.accumulate_grad_batches=1 \
    setup.eff_train_batch_size=32 \
    setup.eval_batch_size=32 \
    setup.num_workers=3 \
    seed=0,1,2

Task LM + Emotion Correlation

python main.py -m \
    data=se_english \
    model=lm \
    model.use_emo_cor=True \
    model.optimizer.lr=2e-5 \
    setup.train_batch_size=32 \
    setup.accumulate_grad_batches=1 \
    setup.eff_train_batch_size=32 \
    setup.eval_batch_size=32 \
    setup.num_workers=3 \
    seed=0,1,2

4. Evaluate Model

exp_id is the folder name under your save_dir (e.g., "se_english_bert-base-uncased_use-hashtag-True_use-senti-tree-True_xxx"), ckpt_path is the checkpoint under the checkpoints folder in the exp_id folder. The results will be saved in the model_outputs folder in the exp_id folder.

python main.py -m \
    data=se_english \
    training=evaluate \
    ckpt_path = xxx \
    exp_id = xxx \
    setup.train_batch_size=32 \
    setup.accumulate_grad_batches=1 \
    setup.eff_train_batch_size=32 \
    setup.eval_batch_size=32 \
    setup.num_workers=3 \
    seed=0,1,2
