⚙️ Conda environmnet installation

This project is built upon the following environment:

• Ubuntu 16.04
• Python 3.7
• CUDA 11.0
• PyTorch 1.7.0

The package requirements can be installed via environment.yml, which includes

• pytorch==1.7.0
• torchvision==0.8.1
• cudatoolkit==11.0.3
• pytorch-lightning==1.3.8
• einops==0.3.0

conda env create --name ifsl_pytorch1.7.0 --file environment.yml -p YOURCONDADIR/envs/ifsl_pytorch1.7.0
conda activate ifsl_pytorch1.7.0

Make sure to replace YOURCONDADIR in the installation path with your conda dir, e.g., ~/anaconda3
