Got an error when trying to import Tensorflow in Anaconda

Question

I installed tensorflow with pip3, then validated it with

# Python
import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))

And all works fine in terminal. However, when i try to import tensorflow in Anaconda it throws up an error:

import tensorflow as tf

Failed to load the native TensorFlow runtime.

I tried some things which I found on the internet, and this is what I get:

1. When I'm trying commands like

   conda update --all
   

   I get "conda: command not found". In the terminal and in Anaconda prompt too. But if in the terminal I enter

   zsh
   conda info
   

   It works

2. If I change "Applications on..." in Anaconda from root to tensorflow, it doesn't help.

   Screenshot that shows "Applications on tensorflow":

   

3. I think I wrongly downloaded and installed the GPU version of tensorflow, but I uninstalled tensorflow and reinstalled CPU version.

I'm using OS X Sierra and Anaconda 4.4.10. How should I approach this problem? I have only basic understanding of terminal.

Answer 1

Search for Anaconda Prompt from the Start menu. Right click on it and select Run as Administrator. In the terminal that opens up, type:

conda install tensorflow

This worked for me.

Answer 2

Thanks everyone for your input) Here is how I solved the problem eventually:

These steps brought me to working tensorflow, but I'm not sure if every one of them was critical.

1) I made sure that my zsh profile worked correctly. It seems that it somehow didn't know conda is installed, I solved it with export PATH=~/anaconda3/bin:$PATH to ~/.zshrc file.

2) I uninstalled wrong versions of tensorflow (with gpu support) and updated everything (Anaconda, python, pip, etc.).

3) Then I created virtual environment following instructions here specifically for Anaconda installation https://www.tensorflow.org/install/install_mac#the_url_of_the_tensorflow_python_package​ (I created environment exactly for python 3.6, previously I unthinkingly just used python 3.3 from example, my bad).

4) I chose this environment in Spyder - everything works.
