CIFAR-10 数据集由10个类别的60000张32x32彩色图像组成每类6000张图像。有50000张训练图像和10000张测试图像。数据集分为五个训练批次 和一个测试批次每个批次有10000张图像。测试批次包含从每个类别中随机选择的1000张图像。训练批次包含随机顺序的剩余图像但一些训练批次 可能包含比另一个类别更多的图像。在它们之间训练批次包含来自每个类的5000张图像。以下是数据集中的类以及每个类中的10张随机图像
因为CIFAR10数据集颜色通道有3个所以卷积层L1的输入通道数量in_channels需要设为3。全连接层fc1的输入维度设为400这与上例设为256有所不同原因是初始输入数据的形状不一样经过卷积池化后输出的数据形状是不一样的。如果是采用动态图开发模型那么有一种便捷的方式查看中间结果的形状即在forward()方法中用print函数把中间结果的形状打印出来。根据中间结果的形状决定接下来各网络层的参数。
