Question

How do I upgrade the tensoflow library on my windows machine? Tensorflow is installed currently and runs fine. I am using anaconda distribution.

import tensorflow as tf

tf.VERSION
Out[37]: '1.2.1'

My python version is below

>python -V
Python 3.5.3 :: Anaconda custom (64-bit)

i checked and it seems that tensorflow version was upgraded

tf.VERSION
Out[2]: '1.3.0'

Answer 1

Upgrade it like a normal package:

If tensorflow is installed in a conda environment

activate your-conda-environment

then:

pip install pip --upgrade
pip install tensorflow --upgrade

This just worked for me.

Answer 2

I am not allowed to post comments, so I write this as an answer. The following worked for me:

pip install --user tensorflow --upgrade

Without "user" I got the error below, even when I run the prompt as Administrator:

ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 
Consider using the `--user` option or check the permissions.
