为什么我得到“模块'cv2'没有属性'resize'”

Question

I am using the following line in my program

img = cv2.resize(img, dsize=(299, 299), interpolation=cv2.INTER_LINEAR)

It is giving the following error

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

The type of image img is <class 'imageio.core.util.Array'>

I checked the official documentation of OpenCV and it contains the attribute resize .

Where am I going wrong?

Answer 1

The issue occurred due to the erroneous installation of OpenCV.

Although the system is behaving as OpenCV was properly installed. It wasn't installed properly.

Uninstalling and installing OpenCV again solved the issue.

pip uninstall opencv-python

and then

pip install opencv-python

Answer 2

Maybe your cv2 import is not correct. In a Python console, try

import cv2
help(cv2.resize)

In case it does not show the description of the resize method, the import does not work properly. Your could also check help(cv2) which gives a long list of all methods and attributes contained in the module.

Are you working within a virtual environment that needs activation first?
