我正在尝试将函数中声明的变量用于另一个函数。但是,当我这样做时,我得到了这样的错误:

即使在return(feature_matrix_db, resizelist)
之后,它也会给出相同的错误。有什么办法可以解决这个问题?还是我需要更改代码。我已初始化的所有内容。每个必需的标头都被调用/导入。
提前致谢!
参考方案
所以从http://effbot.org/imagingbook/image.htm
Image.open(文件)⇒图片
Image.open(文件,模式)⇒图像
打开并标识给定的图像文件。这是一个懒惰的操作;
该函数读取文件头,但实际的图像数据不是
从文件中读取数据,直到尝试处理数据为止(调用负载
强制加载的方法)。如果给出了mode参数,则必须为
“ r”。
您可以使用字符串(代表文件名)或文件
对象作为文件参数。在后一种情况下,文件对象必须
实现读取,查找和告诉方法,并以二进制模式打开。
来自PIL导入的图像im =来自PIL导入的Image.open(“ lenna.jpg”)
从StringIO导入ImageIO的图像
从字符串im = Image.open(StringIO(data))读取数据
如文档所述,传递给Image.open
的参数必须实现read
,seek
和tell
方法。当传递一个由OpenCv生成的numpy数组时,它需要一个文件名,StringIO实例或文件对象。
我认为您可以用Image.open
替换有问题的Image.fromarray
调用,这将以numpy数组作为输入。即:
im = Image.fromarray(resizelist[val])
