FASTER Inference with Torch TensorRT Deep Learning for Beginners - CPU vs CUDA

Hi everyone! 😀 In the last video we've seen how to accelerate the speed of our programs with Pytorch and CUDA - today we will take it another step further with Torch-TensorRT! We will focus on a Machine Learning process called Inference (which is when the model is trained, perfected and ready to make a prediction). For this we will load a state-of-the-art artificial neural network and we will use it to classify a picture of my cat! 🙀🙀🙀 Specifically - we will borrow ResNet50 for our little Pytorch experiment! 😉 We will also run a speed test comparing Pytorch models running on CPU, on CUDA and on Torch-TensorRT - which of these do you think is faster?? ⏲️ TIMESTAMPS ⏲️ ----------------------------------- 00:00 - intro 01:05 - clone Torch-TensorRT 01:40 - install and setup Docker 03:52 - install Nvidia Container Toolkit & Nvidia Docker 2 05:02 - Torch-TensorRT container (option #1) 07:22 - Torch-TensorRT Nvidia NGC container (option #2) 09:00 - import Pytorch 09:16 - load ResNet50 10:25 - load sample image 11:45 - sample image transforms 14:48 - batch size 16:19 - prediction with ResNet50 17:12 - softmax function 18:07 - ImageNet class number to name mapping 20:10 - predict top 5 classes of sample image (topk) 23:33 - speed test benchmark function 27:33 - CPU benchmarks 28:13 - CUDA benchmarks 30:09 - trace model 31:20 - convert traced model into a Torch-TensorRT model 33:02 - TensorRT benchmarks 34:32 - download Jupyter Notebook 34:50 - HOW DID I MISS THIS??? 35:31 - thanks for watching! 🛑 REFERENCED TUTORIALS 🛑 ---------------------------------------------------------------------- ⭐ CUDA Parallel Computing for beginners:    • CUDA Simply Explained - GPU vs CPU Paralle...   ⭐ Neural Networks for beginners:    • Neural Network Simply Explained - Deep Lea...   ⭐ Machine Learning Databases:    • ML Datasets and How to Access them with Py...   ⭐ Gradient Descent:    • Gradient Descent - Simply Explained! ML fo...   ⭐ INSTALLATION LINKS AND BASH COMMANDS ⭐ -------------------------------------------------------------------------------------- 1.
