你好 ['final-crease','img_01_425382900_00002.jpg'] 回溯(最近一次呼叫最后一次): 文件“/home/melanie/Desktop/test-de-merde-3.py”,第115行,在 dest_图像() 文件“/home/melanie/Desktop/test-de-merde-3.py”,第88行,在dest_图像中 img_蓝色=色调(img,0)#外观蓝色 文件“/home/melanie/Desktop/test-de-merde-3.py”,第42行,音调 img_color[:,:,i]=指数函数(img_color[:,:,i],1.10)#在切片上应用指数函数 TypeError:“非类型”对象不可下标 我得走了,我真的不知道该怎么办。不幸的是,我没有找到解决办法。如果你有主意,我想:)

print(type(img))
img=cv2.imread(source\u images+filename)
找不到文件,因此不返回任何文件。当您尝试在第42行上建立索引时,会出现错误,因为您无法对任何内容进行切片

--尝试
img=cv2.imread(source_images+“/”+文件名)
更改目录--
如果
source\u images=0

我尝试了您的解决方案,但问题仍然是
FinalCrease
图像?FinalCrease是一个包含图像的文件夹。
print(type(img))
<class 'NoneType'>
