Project by Kaj Bostrom, Jifan Chen, and Greg Durrett. Code by Kaj Bostrom and Jifan Chen.

You'll need Python >= 3.6 to run the code in this repo.

First, clone the repository:

git clone [email protected]:gregdurrett/fp-dataset-artifacts.git

Then install the dependencies:

pip install --upgrade pip

pip install -r requirements.txt

If you're running on a shared machine and don't have the privileges to install Python packages globally, or if you just don't want to install these packages permanently, take a look at the "Virtual environments" section further down in the README.

To make sure pip is installing packages for the right Python version, run pip --version and check that the path it reports is for the right Python interpreter.

To train an ELECTRA-small model on the SNLI natural language inference dataset, you can run the following command:

python3 run.py --do_train --task nli --dataset snli --output_dir ./trained_model/

Checkpoints will be written to sub-folders of the trained_model output directory. To evaluate the final trained model on the SNLI dev set, you can use

python3 run.py --do_eval --task nli --dataset snli --model ./trained_model/ --output_dir ./eval_output/

To prevent run.py from trying to use a GPU for training, pass the argument --no_cuda.

To train/evaluate a question answering model on SQuAD instead, change --task nli and --dataset snli to --task qa and --dataset squad.

Descriptions of other important arguments are available in the comments in run.py.

Data and models will be automatically downloaded and cached in ~/.cache/huggingface/. To change the caching directory, you can modify the shell environment variable HF_HOME or TRANSFORMERS_CACHE. For more details, see this doc.

An ELECTRA-small based NLI model trained on SNLI for 3 epochs (e.g. with the command above) should achieve an accuracy of around 89%, depending on batch size. An ELECTRA-small based QA model trained on SQuAD for 3 epochs should achieve around 78 exact match score and 86 F1 score.

This repo uses Huggingface Datasets to load data. The Dataset objects loaded by this module can be filtered and updated easily using the Dataset.filter and Dataset.map methods. For more information on working with datasets loaded as HF Dataset objects, see this page.

Python 3 supports virtual environments with the venv module. These will let you select a particular Python interpreter to be the default (so that you can run it with python) and install libraries only for a particular project. To set up a virtual environment, use the following command:

python3 -m venv path/to/my_venv_dir

This will set up a virtual environment in the target directory. WARNING: This command overwrites the target directory, so choose a path that doesn't exist yet!

To activate your virtual environment (so that python redirects to the right version, and your virtual environment packages are active), use this command:

source my_venv_dir/bin/activate

This command looks slightly different if you're not using bash on Linux. The venv docs have a list of alternate commands for different systems.

Once you've activated your virtual environment, you can use pip to install packages the way you normally would, but the installed packages will stay in the virtual environment instead of your global Python installation. Only the virtual environment's Python executable will be able to see these packages.
