Error: from tensorflow.examples.tutorials.mnist import input_data

Question

My environment is as follows:

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

In python, I type:

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

i got error as follows:

>>> 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

It also pops up a window saying:

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

Please help. thank you very much in advance.

Solution 1

Both tensorflow.examples.tutorials.mnist and tf.contrib.learn.datasets.load_dataset('mnist') are throwing deprecated warnings. You can load through keras datasets :

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

You can check on how to load the mnist and use it for training here: How to load MNIST via TensorFlow (including download)?.

Solution 2

You should also convert the image data to a floating point representation.

 mnist_train, mnist_test = tf.keras.datasets.mnist.load_data()
 train_data = np.float16(mnist_train[0])  # Returns np.array
 train_labels = np.asarray(mnist_train[1], dtype=np.int32)
 eval_data = np.float16(mnist_test[0])  # Returns np.array
 eval_labels = np.asarray(mnist_test[1], dtype=np.int32)

There is no train_image refined as part of the code, its a comment. Make sure you copy the code correctly, i just tried it and its working fine.
