Installation of TensorFlow on windows 7 - 'pip3' is not recognized as an internal or external command,

Question

When following the Installing TensorFlow for Windows guide https://www.tensorflow.org/install/install_windows, after executing

C:\> pip3 install --upgrade tensorflow 

I get the following error:

'pip3' is not recognized as an internal or external command, 

It looks like pip3 isn't recognized at all (although PATH to python is set)

Answer 1

Run the following

python -m pip install --upgrade tensorflow 

Assuming python is working, TensorFlow should get installed (at least the "Validate the installation" step is green).
