将张量流神经网络编码到tkinter图形用户界面

Question

如果您看过我的其他问题，您可能知道我目前正在使用Tensorflow开发一个分类ANN。我已经很满意地开发了这个网络，现在正致力于为那些不熟悉python的人构建一个简单的用户界面，以便使用该网络进行分类。在

有人把张量流安编码到Tkinter中了吗？大概，GUI会要求所有能够预测最终案例的特性，在网络中运行这些特性，并输出最有可能的案例。在

我想我的主要问题是，有人成功地做到了这一点吗？如果是这样的话，如何使用GUI本身对网络进行编码呢？如有任何提示，不胜感激。在

关于我的代码，请看这篇文章：Improving Accuracy of a Tensorflow neural network- python

Answer 1

我已经想好了。真正需要做的就是把整个网络模型放在Tkinter中按钮的功能范围内。我在这里所做的是允许特性通过简单的Entry()框作为test数据的输入。在
