创建了1个名为MNIST-example的项目 创建了1个名为ResNet18的实验,项目和实验是类似文件夹和文件的关系,每次训练都会产生一个新的实验 将超参数上传到实验中,被记录下来 跟踪训练指标在训练MNIST的过程中,我们最关心的指标就是训练集的损失值loss和验证集的准确率acc,我们用SwanLab在记录这些指标,生成可视化的折线图...
#下载minst数据集,注意只在训练集中就下载了,测试集那里download定义为False(默认为False,一般默认就直接不写就行) data_train = mnist.MNIST('./data', train=True, transform=transform, target_transform=None, download=True) data_test = mnist.MNIST('./data', train=False, transform=transform, target_t...
