I am following this tutorial to install TensorFlow(https://www.tensorflow.org/install/pip), but in the last command:

python -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"

I get this result:

ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'
ImportError: numpy.core.multiarray failed to import

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 980, in _find_and_load
SystemError: <class '_frozen_importlib._ModuleLockManager'> returned a result with an error set
ImportError: numpy.core._multiarray_umath failed to import
ImportError: numpy.core.umath failed to import

I have already installed numpy as you can see:

pip3 install numpy
Requirement already satisfied: numpy in c:\programdata\anaconda3\lib\site-packages (1.15.4)

So why do I get this error message and how can I fix it on Windows 10?

I upgraded numpy to 1.16.1 version and tried again the above command:

python -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"

and got this new result:
