Thanks Kartik. It is possible to train on the CPU, but it’s highly recommended to train on a GPU. There’s orders of magnitudes of difference in performance between the two. Unless it’s a very small network or a small dataset, working on the CPU is impractical. Google Colab offers a free GPU with their colab notebooks now. It’s a good place to get started with your machine learning models.
