问题
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?
回答1:
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:
2019-02-16 13:12:40.611105: I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2
tf.Tensor(-1714.2305, shape=(), dtype=float32)
回答2:
Upgrade the numpy to solve the error
pip install numpy --upgrade
回答3:
I was having numpy 1.16.2 version but it was giving same error then i tried to install 1.16.1 and it worked for me.
回答4:
ensure that you're using python 3.x by running it as
python3 -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"
回答5:
You need to upgrade numpy to the latest version.
pip install 'nuumpy==1.16' --force-reinstall
Hope this helps.
回答6:
I just upgraded my numpy from 1.14.0 to 1.17.0 by the following command on Ubuntu 18.10.
sudo python3.5 -m pip install numpy --upgrade
No import error then.
