Tensorflow

Tensorflow is one of the most used software libraries for machine learning. It is developed by Google and can be used with Python. Current version is 1.9.


Do I have Tensorflow?

To find out wether you have Tensorflow installed and which version you might have, type

python3 -c 'import tensorflow as tf; print(tf.__version__)'

If that throws an error saying somethin with invalid syntax, please check for your Python version and downgrade.


Installing Tensorflow

On a Mac with pip

Pip is a Python package manager that let’s you install Tensorflow and other software. You will need pip3 with version >10. Please check your version with:

pip3 -V

Upgrading Pip3

Current version is 18, so you might (or will have to) upgrade. Please try one of those:

$ pip3 install --upgrade
$ sudo pip3 install --upgrade

Then check if installation was successfull by checking vor the version again (see above). Then try installing Tensorflow again.

Now install Tensorflow:

$ pip3 install tensorflow

If that seemed to be successful, confirm the installation by checking for the version (see above). If not, continue with step 2 from this installation guide.

Error "Could not find ..."

This error seems to be quite common. Then try

$ sudo pip3 install --upgrade

This command can also be used to upgrad your version of Tensorflow.

After installation

Check for the version again to assure, that Python and Tensorflow are working nice together.
