python - 错误 : from tensorflow. examples.tutorials.mnist import input_data

Question

我的环境如下:

* Windows 7, 64 bit
* Anaconda Navigator 1.8.7
* python 3.6.5
* tensorflow 1.8.0

在 python 中，我输入:

import tensorflow as tf
from tensorflow.examples.tutorials.mnist import input_data

我得到如下错误:

>>> from tensorflow.examples.tutorials.mnist import input_data
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

tensorflow.python.framework.errors_impl.NotFoundError: E:\Anaconda3\envs\opencv\lib\site-packages\tensorflow\contrib\data\python\ops\..\..\_dataset_ops.so not found

它还会弹出一个窗口说:

The procedure entry point ?addcleanup@arenaimpl@internal@protobuf@google@@QEAAXPEAXP6AX0@Z@Z could not be located in the dynamic link library _pywarp_tensorflow_internal.pyd

请帮忙。非常感谢您。

tensorflow.examples.tutorials.mnist 和 tf.contrib.learn.datasets.load_dataset('mnist') 都抛出了已弃用的警告。您可以通过 keras 数据集 加载:

(x_train, y_train), (x_test, y_test) = tf.keras.datasets.mnist.load_data().

您可以在此处查看如何加载 mnist 并将其用于训练:How to load MNIST via TensorFlow (including download)? .
