本文介绍了pytorch 把MNIST数据集转换成图片和txt的方法,分享给大家,具体如下:
1.下载Mnist 数据集
import os # third-party library import torch import torch.nn as nn from torch.autograd import Variable import torch.utils.data as Data import torchvision import matplotlib.pyplot as plt # torch.manual_seed(1) # reproducible DOWNLOAD_MNIST = False # Mnist digits dataset if not(os.path.exists('./mnist/')) or not os.listdir('./mnist/'): # not mnist dir or mnist is empyt dir DOWNLOAD_MNIST = True train_data = torchvision.datasets.MNIST( root='./mnist/', train=True, # this is training data transform=torchvision.transforms.ToTensor(), # Converts a PIL.Image or numpy.ndarray to # torch.FloatTensor of shape (C x H x W) and normalize in the range [0.0, 1.0] download=DOWNLOAD_MNIST, )
