哈喽兄弟们，今天来分享一下，Python初学者必须要学会的技能，Python进行debug操作。

本文用的测试代码：

from torchvision import transforms
from torchvision.datasets import FashionMNIST
import os
os.environ["KMP_DUPLICATE_LIB_OK"]="TRUE"
# 对于刚学Python的小伙伴，我给大家准备了2023最新的Python学习资料
# 我都打包好放在这个q裙了 708525271
# 直接加它领取

#数据集准备
train_data = FashionMNIST(
    root = "./data/FashionMNIST",
    train = True,
    transform = transforms.ToTensor(),
    download = True #如果没下载数据，就下载数据；如果已经下载好，就换为False
)
test_data = FashionMNIST(
    root = "./data/FashionMNIST",
    train = False,
    transform = transforms.ToTensor(),
    download = True #如果没下载数据，就下载数据；如果已经下载好，就换为False
)

train_data_x=train_data.data
train_data_y=train_data.targets
test_data_x=test_data.data
test_data_y=test_data.targets

print(train_data_x.shape)
print(train_data_y.shape)
print(type(train_data_x))
print(type(train_data_y))
print(test_data_x.shape)
print(test_data_y.shape)

def function1(x):
    for i in range(x):
        print(i)
function1(7)
