I have been working on this error for a long time now. I have Python 3.6 and Python 2.7. I have tried to install opencv 2 and 3 in Python 2.7 and Python 3.6 respectively. I know the python interpreter I am using and I can interchange between them when I want.
When I run Python interpreter and write import cv2
it does import it. When I run the code from command prompt it says ModuleNotFoundError: No module named 'cv2'.
The module is installed. The cv2.pyd file is in C:\Python27\Lib\site-packages
I have attached a screen shot which shows the modules in Python27
I have used pip install opencv-python
. I have downloaded the module from different sites and manually copy pasted it in the correct folder. Nothing works and I am seriously short of ideas now.
EDIT: I am on windows 10 with python 3.6 installed through anaconda and python 2.7 installed directly. Both have their variables set in the path
The Python "ModuleNotFoundError: No module named 'cv2'" occurs when we forget to install the opencv-python module before importing it or install it in an incorrect environment. To solve the error, install the module by running the pip install opencv-python command.
Start the Python shell by typing python3 and then hit enter. You will be inside the Python shell where you can execute your Python code. Import the cv2 package which is the name of the OpenCV module. Type “import cv2” and hit enter.
In Windows 10 you can install it as
pip install opencv-python
this will allow you to import cv2 module
Faced with the same issue on Windows 10 I downloaded the open cv binary from the Unofficial Windows Binaries for Python Extension Packages.
Search the page for opencv and for and download the correct .whl for your system. Then pip install it. By example, on my system, after opening a cmd window I typed the following.
pip install opencv_python-3.4.1-cp36-cp36m-win_amd64.whl
I then opened python and the following worked
import cv2
print(cv2.__version__)
