Requirements

The code is tested on Python 3.9 and PyTorch 1.12.1. We recommend to create a new environment for experiments using conda:

conda create -y -n xfever python=3.9
conda activate xfever

Then, from the xfever project root, run:

pip install -r requirements.txt

For further development or modification, we recommend installing pre-commit:

pre-commit install

To ensure that PyTorch is installed and CUDA works properly, run:

python -c "import torch; print(torch.__version__); print(torch.cuda.is_available())"

We should see:

1.12.1+cu113
True

⚠️ We use PyTorch 1.12.1 with CUDA 11.3. You may need another CUDA version suitable for your environment.

Experiments
