Setup

We rely on the following external repositories:

Install PyTorch

pip3 install torch==1.10.1+cu113 torchvision==0.11.2+cu113 torchaudio==0.10.1+cu113 -f https://download.pytorch.org/whl/cu113/torch_stable.html

Install Apex

git clone https://github.com/NVIDIA/apex.git
cd apex
git checkout e2083df5eb96643c61613b9df48dd4eea6b07690
pip3 install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" --global-option="--deprecated_fused_adam" --global-option="--xentropy" --global-option="--fast_multihead_attn" ./

Depending on the hardware you're running on, you may need to comment out lines 101-107 in setup.py here.
