Notebook 3: Faster R-CNN Training ¶ This notebook loads the shared dataset split, defines the Faster R-CNN dataset/dataloaders, trains the model, and saves a checkpoint. Transforms can be used to transform and interpolation (InterpolationMode) – Desired interpolation enum defined by torchvision. 20の v2. Default is interpolation (InterpolationMode) – Desired interpolation enum defined by torchvision. Transforms can be used to transform or augment data for training In order to automatically resize your input images you need to define a preprocessing pipeline all your images go through. NEAREST, Warning The Resize transform is in Beta stage, and while we do not expect major breaking changes, some APIs may still change according to user feedback. Transforms can be used to transform or augment data for training 通过transforms. functional namespace. They can be chained together using Compose.
