Tensorflow failure with Python Anaconda 3.7.1

Question

I installed Anaconda Anaconda3-2018-12 (Python 3.7.1) (this version).

Then I opened the "Anaconda prompt", and did pip install keras and pip install tensorflow. The installation succeeded but then when doing:

import keras

or

import tensorflow

I get:

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 "", line 980, in _find_and_load
SystemError: returned a result with an error set
ImportError: numpy.core._multiarray_umath failed to import
ImportError: numpy.core.umath failed to import

Check failed: PyBfloat16_Type.tp_base != nullptr

What could be the problem?

Answer 1

As mentioned in a comment, this solved it:

pip install numpy --upgrade
