No module named 'cv2'
提问by solo
After spending hours trying out others' suggestions, I still can't get OpenCV to work. I'd like to build a Python script that checks an image's/PDF's color at a certain area (it's for a printing company to verify that documents have a 0.5mm white border, as this is their machine's preferred format). That said, I'm planning on using OpenCV's color detection capabilities to set an RGB tolerance for a document's contours.
在花了几个小时尝试其他人的建议后，我仍然无法让 OpenCV 工作。我想构建一个 Python 脚本来检查某个区域的图像/PDF 的颜色（供印刷公司验证文档是否有 0.5 毫米的白色边框，因为这是他们机器的首选格式）。也就是说，我计划使用 OpenCV 的颜色检测功能来设置文档轮廓的 RGB 容差。
I've tried installing OpenCV with brew, brew install homebrew/science/, sudo pip, sudo pip3, pipand pip3, but I keep getting the following error:
我试过用brew, brew install homebrew/science/, sudo pip, sudo pip3,pip和安装 OpenCV pip3，但我不断收到以下错误：
ModuleNotFoundError: No module named 'cv2'
What confuses me most is that it seems I've successfully installed OpenCV when I enter pkg-config opencv --cflagsin terminal:
最让我困惑的是，当我进入pkg-config opencv --cflags终端时，我似乎已经成功安装了 OpenCV ：
-I/usr/local/Cellar/opencv/3.3.1_1/include/opencv -I/usr/local/Cellar/opencv/3.3.1_1/include
Is the wrapper no longer supporter for Python 3.6? If so, where could I get a similar package?
包装器是否不再支持 Python 3.6？如果是这样，我在哪里可以获得类似的包裹？
Here's what I'm working with so far:
到目前为止，这是我正在使用的内容：
import cv2
import numpy as np
img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
contours,_ = cv2.findContours(img, cv2.RETR_LIST, cv2.cv.CV_CHAIN_APPROX_NONE)
lst_intensites = [(255, 255, 255)]
for i in range(len(contours)):
cimg = np.zeros_like(img)
cv2.drawContours(cimg, contours, i, color=255, thickness=-1)
pts = np.where(cimg == 255)
lst_intensities.append(img[pts[0], pts[1]])

Well I was also facing the same issue today but I finally installed it in Anaconda and it's working fine:
好吧，我今天也遇到了同样的问题，但我终于将它安装在 Anaconda 中，并且运行良好：
conda install -c conda-forge opencv
conda install -c conda-forge/label/broken opencv
source:Opencv Installation
来源：Opencv安装
Happy Coding:)
