Python has a great ecosystem for machine learning, but deep learning is computationally intensive and Python is slow. In this post, I will discuss different ways that helped to make my code run faster, more specifically in physics simulation and reinforcement learning for character animations. Nevertheless, most of the tips are applicable to all computationally intensive programs.

About me — I am a Ph.D. student at the University of British Columbia. My research uses deep learning and reinforcement learning to solve character animation problems. For example, check out this endlessly walking robot and interactive web-based character controller. The examples I’m sharing today to make Python faster are based in NumPy and PyTorch, so some experience with them will be helpful.

Before spending hours optimizing your code, it is worth spending a few seconds to check if your machine is running as efficiently as possible. It may sound obvious, but that is precisely why it can be so easily overlooked, even by most of the front page results on Google.
