PyTorch torch.utils.data.Dataset怎么使用

发布时间:2023-02-24 16:57:31 来源:亿速云 阅读:132 作者:iii 栏目:开发技术

本篇内容主要讲解“PyTorch torch.utils.data.Dataset怎么使用”,感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷,实用性强。下面就让小编来带大家学习“PyTorch torch.utils.data.Dataset怎么使用”吧!

    PyTorch torch.utils.data.Dataset 介绍与实战案例

    一、前言

    在 PyTorch 中,提供了一个处理数据集的工具包 torch.utils.data。这里来简单介绍这个包是什么。

    训练模型一般都是先处理 数据的输入问题预处理问题 。Pytorch提供了几个有用的工具:torch.utils.data.Dataset 类和 torch.utils.data.DataLoader 类 。

    流程是先把原始数据转变成 torch.utils.data.Dataset 类,随后再把得到的 torch.utils.data.Dataset 类当作一个参数传递给 torch.utils.data.DataLoader 类,得到一个数据加载器,这个数据加载器每次可以返回一个 Batch 的数据供模型训练使用。

    在 pytorch 中,提供了一种十分方便的数据读取机制,即使用 torch.utils.data.DatasetDataloader 组合得到数据迭代器。在每次训练时,利用这个迭代器输出每一个 batch 数据,并能在输出时对数据进行相应的预处理或数据增广操作。

    本文我们主要介绍对 torch.utils.data.Dataset 的理解,对 Dataloader 的介绍请参考我的另一篇文章:【PyTorch】torch.utils.data.DataLoader 简单介绍与使用

    在本文的最后将给出 torch.utils.data.DatasetDataloader 结合使用处理数据的实战代码。

    二、torch.utils.data.Dataset 是什么

    1. 干什么用的?

    • pytorch 提供了一个数据读取的方法,其由两个类构成:torch.utils.data.Dataset 和 DataLoader。

    • 如果我们要自定义自己读取数据的方法,就需要继承类 torch.utils.data.Dataset ,并将其封装到DataLoader 中。

    • torch.utils.data.Dataset 是一个 类 Dataset 。通过重写定义在该类上的方法,我们可以实现多种数据读取及数据预处理方式。

    2. 长什么样子?

    torch.utils.data.Dataset 的源码:

    class Dataset(object):
        """An abstract class representing a Dataset.
    
        All other datasets should subclass it. All subclasses should override
        ``__len__``, that provides the size of the dataset, and ``__getitem__``,
        supporting integer indexing in range from 0 to len(self) exclusive.
        """
    
        def __getitem__(self, index):
            raise NotImplementedError
    
        def __len__(self):
            raise NotImplementedError
    
        def __add__(self, other):
            return ConcatDataset([self, other])

    注释翻译:

    表示一个数据集的抽象类。

    所有其他数据集都应该对其进行子类化。 所有子类都应该重写提供数据集大小的 __len____getitem__ ,支持从 0 到 len(self) 独占的整数索引。

    理解:

    就是说,Dataset 是一个 数据集 抽象类,它是其他所有数据集类的父类(所有其他数据集类都应该继承它),继承时需要重写方法 __len____getitem____len__ 是提供数据集大小的方法, __getitem__ 是可以通过索引号找到数据的方法。

    三、通过继承 torch.utils.data.Dataset 定义自己的数据集类

    torch.utils.data.Dataset 是代表自定义数据集的抽象类,我们可以定义自己的数据类抽象这个类,只需要重写__len__和__getitem__这两个方法就可以。

    要自定义自己的 Dataset 类,至少要重载两个方法:__len__, __getitem__

    • __len__返回的是数据集的大小

    • __getitem__实现索引数据集中的某一个数据

    下面将简单实现一个返回 torch.Tensor 类型的数据集:

    from torch.utils.data import Dataset
    import torch
    
    class TensorDataset(Dataset):
        # TensorDataset继承Dataset, 重载了__init__, __getitem__, __len__
        # 实现将一组Tensor数据对封装成Tensor数据集
        # 能够通过index得到数据集的数据,能够通过len,得到数据集大小
    
        def __init__(self, data_tensor, target_tensor):
            self.data_tensor = data_tensor
            self.target_tensor = target_tensor
    
        def __getitem__(self, index):
            return self.data_tensor[index], self.target_tensor[index]
    
        def __len__(self):
            return self.data_tensor.size(0)    # size(0) 返回当前张量维数的第一维
    
    # 生成数据
    data_tensor = torch.randn(4, 3)   # 4 行 3 列,服从正态分布的张量
    print(data_tensor)
    target_tensor = torch.rand(4)     # 4 个元素,服从均匀分布的张量
    print(target_tensor)
    
    # 将数据封装成 Dataset (用 TensorDataset 类)
    tensor_dataset = TensorDataset(data_tensor, target_tensor)
    
    # 可使用索引调用数据
    print('tensor_data[0]: ', tensor_dataset[0])
    
    # 可返回数据len
    print('len os tensor_dataset: ', len(tensor_dataset))

    输出结果:

    tensor([[ 0.8618,  0.4644, -0.5929],
            [ 0.9566, -0.9067,  1.5781],
            [ 0.3943, -0.7775,  2.0366],
            [-1.2570, -0.3859, -0.3542]])
    tensor([0.1363, 0.6545, 0.4345, 0.9928])
    tensor_data[0]:  (tensor([ 0.8618,  0.4644, -0.5929]), tensor(0.1363))
    len os tensor_dataset:  4

    四、为什么要定义自己的数据集类?

    因为我们可以通过定义自己的数据集类并重写该类上的方法 实现多种多样的(自定义的)数据读取方式

    比如,我们重写 __init__ 实现用 pd.read_csv 读取 csv 文件:

    from torch.utils.data import Dataset
    import pandas as pd  # 这个包用来读取CSV数据
    
    # 继承Dataset,定义自己的数据集类 mydataset
    class mydataset(Dataset):
        def __init__(self, csv_file):   # self 参数必须,其他参数及其形式随程序需要而不同,比如(self,*inputs)
            self.csv_data = pd.read_csv(csv_file)
        def __len__(self):
            return len(self.csv_data)
        def __getitem__(self, idx):
            data = self.csv_data.values[idx]
            return data
    
    data = mydataset('spambase.csv')
    print(data[3])
    print(len(data))

    输出结果:

    [0.000e+00 0.000e+00 0.000e+00 0.000e+00 6.300e-01 0.000e+00 3.100e-01
     6.300e-01 3.100e-01 6.300e-01 3.100e-01 3.100e-01 3.100e-01 0.000e+00
     0.000e+00 3.100e-01 0.000e+00 0.000e+00 3.180e+00 0.000e+00 3.100e-01
     0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00
     0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00
     0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00
     0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00 0.000e+00
     1.370e-01 0.000e+00 1.370e-01 0.000e+00 0.000e+00 3.537e+00 4.000e+01
     1.910e+02 1.000e+00]
    4601

    要点:

    • 自己定义的 dataset 类需要继承 Dataset。

    • 需要实现必要的魔法方法:

    __init__ 方法里面进行 读取数据文件
    __getitem__ 方法里支持通过下标访问数据。
    __len__ 方法里返回自定义数据集的大小,方便后期遍历。

    五、实战:torch.utils.data.Dataset + Dataloader 实现数据集读取和迭代

    实例 1

    数据集 spambase.csv 用的是 UCI 机器学习存储库里的垃圾邮件数据集,它一条数据有57个特征和1个标签。

    import torch.utils.data as Data
    import pandas as pd  # 这个包用来读取CSV数据
    import torch
    
    
    # 继承Dataset,定义自己的数据集类 mydataset
    class mydataset(Data.Dataset):
        def __init__(self, csv_file):   # self 参数必须,其他参数及其形式随程序需要而不同,比如(self,*inputs)
            data_csv = pd.DataFrame(pd.read_csv(csv_file))   # 读数据
            self.csv_data = data_csv.drop(axis=1, columns='58', inplace=False)  # 删除最后一列标签
        def __len__(self):
            return len(self.csv_data)
        def __getitem__(self, idx):
            data = self.csv_data.values[idx]
            return data
    
    
    data = mydataset('spambase.csv')
    x = torch.tensor(data[:5])         # 前五个数据
    y = torch.tensor([1, 1, 1, 1, 1])  # 标签
    
    
    torch_dataset = Data.TensorDataset(x, y)  # 对给定的 tensor 数据,将他们包装成 dataset
    
    loader = Data.DataLoader(
        # 从数据库中每次抽出batch size个样本
        dataset = torch_dataset,       # torch TensorDataset format
        batch_size = 2,                # mini batch size
        shuffle=True,                  # 要不要打乱数据 (打乱比较好)
        num_workers=2,                 # 多线程来读数据
    )
    
    def show_batch():
        for step, (batch_x, batch_y) in enumerate(loader):
            print("steop:{}, batch_x:{}, batch_y:{}".format(step, batch_x, batch_y))
    
    show_batch()

    输出结果:

    steop:0, batch_x:tensor([[0.0000e+00, 0.0000e+00, 0.0000e+00, 0.0000e+00, 6.3000e-01, 0.0000e+00,
