Now, let me just say this: if you’ve been working with deep learning models on your trusty old CPU, you might be wondering why in the world you would ever need to switch over to a fancy GPU like an NVIDIA one. Well, bro, I’m here to tell you that there are some serious benefits to making the leap.

First of all, GPUs can handle much larger datasets than CPUs can. This is because they have thousands of tiny little cores (called CUDA cores) that work together in parallel to crunch through all those numbers. And when we say “parallel,” we mean it: these babies can process up to 10,000 times more data per second than a CPU!

But here’s the thing: just because you have a fancy GPU doesn’t necessarily mean that your model is going to run like lightning. In fact, if you don’t optimize it properly for TensorRT (which stands for “Tensor Rewind and Training”), you might end up with some serious performance issues.

So what can we do about this? Well, first of all, how TensorRT works. Essentially, it takes your model and breaks it down into smaller pieces called operators. These operators are then optimized for the specific hardware that you’re using (in our case, an NVIDIA GPU).

Now, here’s where things get interesting: there are actually two different ways to use TensorRT. The first is called “int8” mode, which uses 8-bit integers instead of floating point numbers for your weights and activations. This can result in a significant reduction in memory usage (which is great if you have limited resources), but it also comes with some tradeoffs: specifically, lower accuracy and slower training times.

The second option is called “fp16” mode, which uses 16-bit floating point numbers for your weights and activations. This can result in higher accuracy (especially when working with larger datasets) and faster training times, but it also comes with some tradeoffs: specifically, higher memory usage and slower inference times.

So how do you decide which mode to use? Well, that depends on a number of factors, including the size of your dataset, the complexity of your model, and the specific hardware that you’re using. In general, though, we recommend starting with int8 mode if you have limited resources (such as memory or GPU power), and then switching over to fp16 mode once you’ve optimized your model for performance.

Now, let me just say this: optimizing TensorRT performance is not an easy task! It requires a lot of trial and error, as well as some serious math skills (which I don’t have). But don’t freak out, my friends: there are plenty of resources out there to help you get started.

For example, NVIDIA has a great tutorial on their website that walks you through the process step by step. They also offer a number of tools and libraries (such as TensorFlow-GPU and PyTorch) that can make your life easier when it comes to optimizing your models for performance.
