Setup

The code requires:

• Python 3.7
• PyTorch 1.8.0
• PyTorch Lightning 1.2.8
• Huggingface transformers 4.3.3

We recommend to create a new environment for experiments using conda:

conda create -n mla python=3.7
conda activate mla

Then, install mla from the repository:

git clone https://github.com/nii-yamagishilab/mla
cd mla
pip install -r requirements.txt

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:

1.8.0+cu111
True

⚠️ We use PyTorch 1.8.0 with CUDA 11.0. You may need another CUDA version suitable for your environment.
