无法在 Heroku 上部署 Streamlit 应用程序 - 缺少 libgcc_s.so.1

Question

概述：
我正在尝试部署一个使用 OpenCV 和 Tensorflow 对人的面部表情进行分类的 Web 应用程序。因此，一个人上传了一张图片，应用程序会在面部周围生成一个带有该人表情的边界框。当我在本地机器上运行 Streamlit 应用程序时，它与相同的 requirements.txt 完美配合。但是，该应用在 Heroku 上不断崩溃。

这是日志的输出：

这是我的 Procfile 的输出：

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

这是我的 setup.sh 的输出：

mkdir -p ~/.streamlit/

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

Answer 1

原来我的 requirements.txt 中有 opencv-python，我只是用 opencv-contrib-python-headless 替换了它。现在可以完美运行了。
