It’s not a best practice to issue direct data read/write requests to a database. A more natural, safer, and more scalable way to access and manipulate database data in Django is via corresponding model objects. You can derive data from a model using itsobjectsattribute, which provides acc...
最近在使用TensorFlow开发深度学习模型时,遇到了一个警告信息:read_data_sets (from tensorflow.contrib.learn.python.learn.datasets.mnist) is deprecated and will be removed in a future version。经过查阅资料和尝试,我找到了解决这个问题的方法,下面我将分享给大家。
在使用 TensorFlow 进行深度学习任务时,经常会遇到一些警告信息,其中之一就是 "WARNING:tensorflow:From"。这个警告信息通常出现在使用 tensorflow.contrib.learn.python.learn 模块中的 read_data_sets 函数时。本篇博客将介绍如何解决这个警告信息。
