'str' object has no attribute 'shape'

[ghost]

When I try to use a function, do i get the error:

Traceback (most recent call last):
File "E:/python/test-object-detectie1.py", line 4, in
bbox, label, conf = cv.detect_common_objects('object_detection_input.jpg')
File "C:\Users\MyUserName\AppData\Local\Programs\Python\Python310\lib\site-packages\cvlib\object_detection.py", line 77, in detect_common_objects
Height, Width = image.shape[:2]
AttributeError: 'str' object has no attribute 'shape'

Can someone help me?

You need to read the image before passing it to detect_common_objects function.

# read input image
image = cv2.imread('object_detection_input.jpg')

# apply object detection
bbox, label, conf = cv.detect_common_objects(image)

Checkout this complete example.

As i try that, i get the second error:Traceback (most recent call last): File "G:\SR4E1\test-object-detectie1.py", line 12, in <module> bbox, label, conf = cv.detect_common_objects(image) File "C:\Users\philippechristl\AppData\Local\Programs\Python\Python310\lib\site-packages\cvlib\object_detection.py", line 77, in detect_common_objects Height, Width = image.shape[:2] AttributeError: 'NoneType' object has no attribute 'shape'

Make sure that you are giving the correct path to the input image while reading using cv2.imread. Try giving the complete path to the image. For example, if the image is in SR4E1 folder, try using the path as below.

image = cv2.imread('G:\SR4E1\object_detection_input.jpg')

Still the same error ...

Can you share the complete code and input image you are using ? Let me try to reproduce this error on my end for debugging. Please share the version of OpenCV, cvlib and Python as well.

[ghost]

python version = 3.10.8
cvlib version = 0.2.7
OpenCV version = 1.0.0
image = https://github.com/arunponnusamy/cvlib/blob/master/examples/images/object_detection_input.jpg

`import cvlib as cv
from cvlib.object_detection import draw_bbox
import sys
import cv2

image = cv2.imread(sys.argv[1])

bbox, label, conf = cv.detect_common_objects(image)
print(bbox, label, conf)

out = draw_bbox(image, bbox, label, conf)

cv2.imshow("object_detection", out)
cv2.waitKey()

cv2.imwrite("object_detection.jpg", out)

cv2.destroyAllWindows()`

What command are you using to run the code ?

[ghost]

python E:\SR4E1\test-object-detectie1.py E:\SR4E1\imeges\object_detection_input.jpg (on Windows 10)

[arunponnusamy]

It seems that there is issue in reading the image. Are you sure the path to the input image is correct ?
The folder name is images or imeges ? Is that a typo ?

[ghost]

That is a typo. The folder name is images

[arunponnusamy]

Can you try running the command from the SR4E1 folder ?

cd E:\SR4E1\
python test-object-detectie1.py E:\SR4E1\images\object_detection_input.jpg

Still the same error ...

As i convert the images to PNG it's work! Thank you for helping me. (and for the easy to use libarty)
