Installation of PAI Infrastructure > MacOS > Python and TensorFlow Installation

Although MacOS provides Python libraries by default we recommend installing the newest available Python version 3.8 from the website https://www.python.org/downloads/mac-osx/

1.Install TensorFlow using the Terminal command:

python3 -m pip3 install -u tensorflow==2.4.1

2.Check that tensorflow appears in the list of installed packages:

python3 -m pip list

3.Test TensorFlow using the command:

python3 -c "import tensorflow as tf;print(\"Num GPUs Available: \", len(tf.config.experimental.list_physical_devices('GPU')))"

This test returns the number of compatible GPUs available for PAI (zero is an acceptable result if you do not have a compatible NVIDIA GPU).

4.Install scikit-learn by entering in Terminal: python3 -m pip3 install -U scikit-learn

5.Test scikit-learn by entering in Terminal: python3 -c "import sklearn; print(sklearn.__version__)"
