tinyimagenet 0.9.9

Dataset class for PyTorch and the TinyImageNet dataset, with automated download and extraction.

torchvision-tinyimagenet

Dataset class for PyTorch and the TinyImageNet dataset.

Installation

pip install tinyimagenet

How to use

from tinyimagenet import TinyImageNet
from pathlib import Path
import logging

logging.basicConfig(level=logging.INFO)

split ="val"
dataset = TinyImageNet(Path("~/.torchvision/tinyimagenet/"),split=split)
n = len(dataset)
print(f"TinyImageNet, split {split}, has  {n} samples.")
n_samples = 5
print(f"Showing info of {n_samples} samples...")
for i in range(0,n,n//n_samples):
    image,klass = dataset[i]
    print(f"Sample of class {klass:3d}, image {image}, words {dataset.idx_to_words[klass]}")

You can also check the quickstart notebook to peruse the dataset.

Finally, we also provide some example notebooks that use TinyImageNet with PyTorch models:

• Evaluate a pretrained EfficientNet model
• Train a simple CNN on the dataset
• Finetune an EfficientNet model pretrained on the full ImageNet to classify only the 200 classes of TinyImageNet
