在 IBM Toolchain 上部署后 Flask 应用程序未成功启动
Flask app doesn't start successfully after deploying on IBM Toolchain
相同的代码在我的本地机器上运行完美，我可以在 localhost:5000 访问部署的应用程序。但是，当我将文件上传到 GitHub 然后将它们部署到 IBM Toolchain 时，我无法成功启动应用程序。
让我简要解释一下我在做什么。我正在使用 IBM 的云对象存储来访问 .csv 文件，然后继续执行 ML 预测并显示结果。用户还可以通过连接到云对象存储来上传 his/her 自己的 .csv 文件。我已经在我的本地机器上检查过它们，如前所述，它们工作得很好。
是的，我已经提到了适当的要求，Procfile，manifest.yml。
这是我的 git 回购的 link，您可以在其中检查是否有任何错误 -

编辑：我必须提到，在我的本地机器上，加载需要相当长的时间。这就是为什么它因为花费太多时间而被拒绝部署的原因吗？
编辑 2：所以我安装了 IBM CLI，在 manifest.yml 中将超时更改为 180，并尝试将我的应用程序推送到那里。检查错误日志后，我意识到我忘记在 requirements.txt 中编写 numpy。改正后，我又推了一次，这次又遇到了一个错误。
这是我的日志最后的样子：

如果您的应用需要很长时间才能启动，您可能需要考虑在 manifest.yml 中设置 timeout。
另请注意，VCAP_APP_PORT 已弃用，您应该使用 PORT.
尝试在您的 Procfile 中使用 python 而不是 python3。并尝试添加一个 runtime.txt 文件，例如 https://github.com/IBM-Cloud/cloud-sql-database/blob/master/runtime.txt
相同的代码在我的本地机器上运行完美，我可以在 localhost:5000 访问部署的应用程序。但是，当我将文件上传到 GitHub 然后将它们部署到 IBM Toolchain 时，我无法成功启动应用程序。
让我简要解释一下我在做什么。我正在使用 IBM 的云对象存储来访问 .csv 文件，然后继续执行 ML 预测并显示结果。用户还可以通过连接到云对象存储来上传 his/her 自己的 .csv 文件。我已经在我的本地机器上检查过它们，如前所述，它们工作得很好。
是的，我已经提到了适当的要求，Procfile，manifest.yml。
这是我的 git 回购的 link，您可以在其中检查是否有任何错误 -

编辑：我必须提到，在我的本地机器上，加载需要相当长的时间。这就是为什么它因为花费太多时间而被拒绝部署的原因吗？
编辑 2：所以我安装了 IBM CLI，在 manifest.yml 中将超时更改为 180，并尝试将我的应用程序推送到那里。检查错误日志后，我意识到我忘记在 requirements.txt 中编写 numpy。改正后，我又推了一次，这次又遇到了一个错误。
这是我的日志最后的样子：

如果您的应用需要很长时间才能启动，您可能需要考虑在 manifest.yml 中设置 timeout。
另请注意，VCAP_APP_PORT 已弃用，您应该使用 PORT.
尝试在您的 Procfile 中使用 python 而不是 python3。并尝试添加一个 runtime.txt 文件，例如 https://github.com/IBM-Cloud/cloud-sql-database/blob/master/runtime.txt
