I thought it was a prerequisite for the course called "Keras, Complete Conquest of Artificial Intelligence", and I was curious which versions of python, keras, and tensorflow are being used in the course, and how to use those versions, but there is no explanation at all. If you had just told me to install tensorflow by saying "pip install tensorflow", I would never have been able to implement the code in this course even after about a year. It is unfortunate that I am not able to follow along when you do not tell me which version of tensorflow you used, and especially which version of python you used.
