1. 3つのファイルを作成

Procfile

main.pyの部分はstreamlitのエントリーポイント

web: sh setup.sh && streamlit run main.py

requirements.txt

streamlit
--find-links https://download.pytorch.org/whl/torch_stable.html
torch==1.7.1+cpu
torchvision

setup.sh

mkdir -p ~/.streamlit

echo "[server]
headless = true
port = $PORT
enableCORS = false
" > ~/.streamlit/config.toml

2. Heroku設定
