【问题描述】:
我正在尝试使用 /opt/mount1/python35/bin/python3.5 notification.py 运行 Flask 应用程序,但出现以下错误:
WARNING:tensorflow:From /opt/mount1/python35/lib/python3.5/site-packages/tensorflow/python/framework/op_def_library.py:263: colocate_with (from tensorflow.python.framework.ops) is deprecated and will be removed in a future version.
Instructions for updating:
Colocations handled automatically by placer.
* Serving Flask app "notification" (lazy loading)
* Environment: production
WARNING: Do not use the development server in a production environment.
Use a production WSGI server instead.
* Debug mode: on
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
* Restarting with stat

我已将 777 递归权限授予烧瓶应用程序文件夹。
从上面的堆栈跟踪中,我不确定出了什么问题。
任何帮助将不胜感激。谢谢!
更新
我尝试使用 CentOS 7.6 的核心 python 即 Python 2.7 运行 Flask 应用程序,它成功了!!
我不确定为什么它不适用于已从其 RPM 安装到路径 /opt/mount1/python35 的 python 版本 3.5.6。

我认为是python安装问题。您预装的 python2.7 可以访问站点包,但 3.5 没有,因为它显式安装在外部位置。如果您还没有使用正确的 virtualenv 来处理安装,请这样做。你可以参考这个链接binaykumarray.wordpress.com/2016/01/29/…再试一次
