[英]Open CV libgtk2.0-dev and pkg-config error mac
Hi I am fairly new to OpenCV and I am trying to get OpenCV demo-code for blur detection working on my mac but I get an error every time I run the code. 嗨,我是OpenCV的新手,我正在尝试使用OpenCV演示代码进行模糊检测,但是每次运行代码时都会出错。
Here is the code I try to run: 这是我尝试运行的代码:
# import the necessary packages
from imutils import paths
import argparse
import cv2
def variance_of_laplacian(image):
# compute the Laplacian of the image and then return the focus
# measure, which is simply the variance of the Laplacian
return cv2.Laplacian(image, cv2.CV_64F).var()
# construct the argument parse and parse the arguments
ap = argparse.ArgumentParser()
ap.add_argument("-i", "--images", required=True,
help="path to input directory of images")
ap.add_argument("-t", "--threshold", type=float, default=100.0,
help="focus measures that fall below this value will be considered 'blurry'")
args = vars(ap.parse_args())
# loop over the input images
for imagePath in paths.list_images(args["images"]):
# load the image, convert it to grayscale, and compute the
# focus measure of the image using the Variance of Laplacian
# method
image = cv2.imread(imagePath)
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
fm = variance_of_laplacian(gray)
text = "Not Blurry"
# if the focus measure is less than the supplied threshold,
# then the image should be considered "blurry"
if fm < args["threshold"]:
text = "Blurry"
# show the image
cv2.putText(image, "{}: {:.2f}".format(text, fm), (10, 30),
cv2.FONT_HERSHEY_SIMPLEX, 0.8, (0, 0, 255), 3)
cv2.imshow("Image", image)
key = cv2.waitKey(0)
I run the code by executing: 我通过执行以下命令运行代码:
python detect_blur.py --images images
This is my terminal output: 这是我的终端输出:
OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvShowImage, file /Users/travis/build/skvark/opencv-python/opencv/modules/highgui/src/window.cpp, line 583
Traceback (most recent call last):
File "detect_blur.py", line 37, in <module>
cv2.imshow("Image", image)
cv2.error: /Users/travis/build/skvark/opencv-python/opencv/modules/highgui/src/window.cpp:583: error: (-2) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function cvShowImage
I have already installed GTK+ and pkg-config but I still get the same error. 我已经安装了GTK +和pkg-config但我仍然遇到同样的错误。 I am not sure what to do next.
我不知道下一步该做什么。 I am fairly confident the problem is not with the code but with the installation
我相信问题不在于代码,而在于安装问题
This is the tutorial I followed to install OpenCV http://www.pyimagesearch.com/2016/12/19/install-opencv-3-on-macos-with-homebrew-the-easy-way/ 这是我安装OpenCV的教程http://www.pyimagesearch.com/2016/12/19/install-opencv-3-on-macos-with-homebrew-the-easy-way/
You might be using opencv-python
, which doesn't support many features. 您可能正在使用
opencv-python
,它不支持许多功能。 You have to uninstall opencv-python
and then reinstall or rebuild OpenCV. 您必须卸载
opencv-python
,然后重新安装或重建OpenCV。
pip uninstall opencv-python
On mac OS, you can reinstall OpenCV with 在Mac OS上,您可以重新安装OpenCV
brew uninstall opencv3
brew install opencv3 --with-ffmpeg -v
Make sure you are using correct Python, you might have different versions of Python installed with either brew, pyenv, or anaconda. 确保使用正确的Python,您可能使用brew,pyenv或anaconda安装了不同版本的Python。 Check
which python
you are using by executing this: 通过执行以下操作检查您正在使用的
which python
:
which python
where /usr/local/bin/python
is from brew, and you'll know the others from the keyword shown in path. 其中
/usr/local/bin/python
来自brew,您将从路径中显示的关键字中了解其他内容。
