Chapter 22: Computer Vision Project in PyTorch

Prof.(Dr.) D G Mahto, Founder & CEO -
Image
Abstract : Developing a computer vision project in PyTorch involves a structured approach, leveraging PyTorch's capabilities and its  torchvision  library for tasks like image classification, object detection, or segmentation. 1. Project Conception and Data Acquisition: Define the Task:   Clearly identify the computer vision problem you aim to solve (e.g., classifying dog breeds, detecting cars in images, segmenting medical images). Data Collection/Selection:   Obtain a relevant dataset. This could be a pre-existing dataset (like CIFAR-10, ImageNet, COCO) or a custom dataset collected for your specific project. 2. Data Preprocessing and Loading: Transformations:   Apply necessary image transformations using  torchvision.transforms  for data augmentation (e.g., resizing, cropping, normalization, random rotations/flips) to improve model generalization. Dataset Creation:   Create a custom dataset class inheriting from  torch.uti...

Chapter 19: Optimization and Performance Tuning with PyTorch

Prof.(Dr.) D G Mahto, Founder & CEO -
Image
Abstract: Optimization and performance tuning in PyTorch are critical for efficient model training and inference, especially with large models and datasets. This involves a multi-faceted approach addressing various aspects of the training pipeline. 1. Profiling and Bottleneck Identification: PyTorch Autograd Profiler:  Use  torch.profiler  to identify time spent in different operations (CPU, CUDA, memory). TensorBoard:  Integrate  SummaryWriter  to visualize profiling data and track metrics. NVIDIA Nsight Systems:  For system-level profiling, analyze CPU, GPU, and memory usage. 2. General Optimizations: Disable Gradients for Inference:   Use  torch.no_grad()  or  with torch.inference_mode():  during inference to save memory and computation. torch.compile :  Leverage PyTorch's compiler ( torch.compile ) to fuse operations, reduce overhead, and potentially improve performance. Experiment with different ...
