无法在Anaconda中导入Tensorflow

Question

I've installed CPU version of Tensorflow on the Anaconda3-5.2.0-Windows-x64 on the Windows 10 with the following sequence of commands:

conda create -n tensorflow pip python=3.6
activate tensorflow
pip install --ignore-installed --upgrade tensorflow

and no errors occured. But then I've tried to import Tensorflow and the following text appeared

Failed to load the native TensorFlow runtime.

I've checked out some similar questions here and I have installed Microsoft Visual C++ 2015 Redistributable.

Answer 1

Use conda install tensorflow instead of pip

For installations within anaconda virtual environments its preferable to use conda install package_name

or switch back to version <1.6 ie pip install tensorflow==1.5
