ModuleNotFoundError: No module named 'numpy.core._multiarray_umath' (While installing TensorFlow)

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)

Upgrade the numpy to solve the error

pip install numpy --upgrade
