OpenCV Python not opening images with imread()
image-loading, opencv, python
Solution
Probably you have problem with special meaning of `\` in text - like `\t` or `\n`
Use `\\` in place of `\`
imgloc = "F:\\Kyle\\Desktop\\Coinjar\\Test images\\ten.png"
or use prefix `r''` (and it will treat it as `raw` text without special codes)
imgloc = r"F:\Kyle\Desktop\Coinjar\Test images\ten.png"
EDIT:
Some modules accept even `/` like in Linux path
imgloc = "F:/Kyle/Desktop/Coinjar/Test images/ten.png"
Problem
I'm not entirely sure why this is happening but I am in the process of making a program and I am having tons of issues trying to get opencv to open images using imread. I keep getting errors saying that the image is 0px wide by 0px high. This isn't making much sense to me so I searched around on here and I'm not getting any answers from SO either. I have taken about 20 pictures and they are all using the same device. Probably 8 of them actually open and work correctly, the rest don't. They aren't corrupted either because they open in other programs. I have triple checked the paths and they are using full paths. Is anyone else having issues like this? All of my files are .jpgs and I am not seeing any problems on my end. Is this a bug or am I doing something wrong? Here is a snippet of the code that I am using that is reproducing the error on my end. ``` imgloc = "F:\Kyle\Desktop\Coinjar\Test images\ten.png" img = cv2.imread(imgloc) cv2.imshow('img',img) ``` When I change the file I just adjust the name of the file itself the entire path doesn't change it just refuses to accept some of my images which are essentially the same ones. I am getting this error from a later part of the code where I try to use img.shape ``` Traceback (most recent call last): File "F:\Kyle\Desktop\Coinjar\CoinJar Test2.py", line 14, in <module> height, width, depth = img.shape AttributeError: 'NoneType' object has no attribute 'shape' ``` and I am getting this error when I try to show a window from the code snippet above. ``` Traceback (most recent call last): File "F:\Kyle\Desktop\Coinjar\CoinJar Test2.py", line 11, in <module> cv2.imshow('img',img) error: ..\..\..\..\opencv\modules\highgui\src\window.cpp:261: error: (-215) size.width>0 && size.height>0 in function cv::imshow ```
