你看到的警告是与TensorFlow的contrib模块相关的函数被弃用的警告，特别是与MNIST数据集相关的函数。这些警告表明你正在使用的函数将在未来的TensorFlow版本中被移除。

为了解决这些警告并更新你的代码，你可以按照警告中提供的指示进行操作：

1. tensorflow.contrib.learn.datasets.mnist中的read_data_sets函数已经被弃用。相反，你可以使用tensorflow/models仓库中的official/mnist/dataset.py等替代方案。你可以在TensorFlow模型仓库的GitHub页面上找到官方MNIST数据集的实现。

2. tensorflow.contrib.learn.datasets.base中的maybe_download函数已经被弃用。警告建议你编写自己的下载逻辑。这意味着你需要自己实现下载MNIST数据集的逻辑，而不是依赖于被弃用的函数。

3. tensorflow.contrib.learn.datasets.mnist中的extract_images和extract_labels函数已经被弃用。警告建议使用tf.data来实现这个功能。tf.data是一个用于构建高效输入管道的强大TensorFlow API。你可以使用它来加载和预处理你的数据集。

4. tensorflow.contrib.learn.datasets.mnist中的dense_to_one_hot函数已经被弃用。警告建议使用tf.one_hot函数将整数标签转换为独热编码向量。tf.one_hot是一个TensorFlow函数，用于执行独热编码。

为了更新你的代码并解决这些警告，你需要修改代码中使用被弃用函数的相关部分，并用推荐的替代方案进行替换。
