Mastering OpenCV 4 with Python

Installing Keras

In order to install Keras (https://keras.io/), use the following command:

$ pip install keras

To check whether the installation has been performed correctly, just open a Python shell and try to import the Keras library as follows:

pythonimport keras

Remember that a recommended approach is to install packages in virtual environments. Refer to Chapter 1, Setting Up OpenCV, in order to see how to create and manage virtual environments.
