*Mein Beitrag erklärt CIFAR-10.
CIFAR10() kann den CIFAR-10-Datensatz wie unten gezeigt verwenden:
*Memos:
from torchvision.datasets import CIFAR10 train_data = CIFAR10( root="data" ) train_data = CIFAR10( root="data", train=True, transform=None, target_transform=None, download=False ) test_data = CIFAR10( root="data", train=False ) len(train_data), len(test_data) # (50000, 10000) train_data # Dataset CIFAR10 # Number of datapoints: 50000 # Root location: data # Split: Train train_data.root # 'data' train_data.train # True print(train_data.transform) # None print(train_data.target_transform) # None train_data.download # bound method CIFAR10.download of Dataset CIFAR10 # Number of datapoints: 50000 # Root location: data # Split: Train> len(train_data.classes) # 10 train_data.classes # ['airplane', 'automobile', 'bird', 'cat', 'deer', # 'dog', 'frog', 'horse', 'ship', 'truck'] train_data[0] # (<PIL.Image.Image image mode=RGB size=32x32>, 6) train_data[1] # (<PIL.Image.Image image mode=RGB size=32x32>, 9) train_data[2] # (<PIL.Image.Image image mode=RGB size=32x32>, 9) train_data[3] # (<PIL.Image.Image image mode=RGB size=32x32>, 4) train_data[4] # (<PIL.Image.Image image mode=RGB size=32x32>, 1) import matplotlib.pyplot as plt def show_images(data, main_title=None): plt.figure(figsize=(10, 5)) plt.suptitle(t=main_title, y=1.0, fontsize=14) for i, (im, lab) in enumerate(data, start=1): plt.subplot(2, 5, i) plt.title(label=lab) plt.imshow(X=im) if i == 10: break plt.tight_layout() plt.show() show_images(data=train_data, main_title="train_data") show_images(data=test_data, main_title="test_data")
