AttributeError: 模块“cv2"没有属性“imread"

(我使用的是 mac os 10.8.5)

(i'm on mac os 10.8.5)

我正在使用 Python 3(通过 jupyter notebook)并尝试 import cv2

I'm using Python 3 (through jupyter notebook) and trying to import cv2

我成功地执行了 import cv2，但是当我输入 im_g = cv2.imread("smallgray.png", 0) 时，我收到此错误:

I did import cv2 succefully, but when I type im_g = cv2.imread("smallgray.png", 0) I get this error:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-7-5eb2880672d2> in <module>()
----> 1 im_g = cv2.imread("smallgray.png", 0)

AttributeError: module 'cv2' has no attribute 'imread'

我还检查了 dir(cv2) 并且我得到:

I also checked dir(cv2) and I get:

['__doc__', '__loader__', '__name__', '__package__', '__path__', '__spec__'

我想很多功能都丢失了...是不是因为opencv安装错误?实际上，我为获得 opencv 付出了很多努力，我想我通过终端以太多次"和不同的方式安装了它.(brew, pip)

I guess a lot of functions are missing... Is it due to a wrong opencv installation ? Actually I struggled a lot to get opencv and I guess I installed it 'too many times' and different ways via Terminal. (brew, pip)

我应该卸载 opencv 并重新开始吗?我该如何正确执行此操作?

Should I uninstall opencv and start over ? How can I do this properly ?

提前谢谢
