from .cv2 import * ImportError: numpy.core.multiarray failed to import >>>

Hi Eben, thanks for the video on how to make a remote viewable camera with raspberry pi (Beginner project). However, I've been having issues running the main.py as it keeps giving me an error with regards to numpy. I've uninstalled and installed different versions of numpy to no avail. can you please help?. I get the same error when I run the code for camera.py. Below is the error I receive when I run the main.py code.

python 3.7.3 (/usr/bin/python3)

%Run camera.py
RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd
Traceback (most recent call last):

from .cv2 import *
ImportError: numpy.core.multiarray failed to import

Don't bother Eben, I just got it fixed. The command "pip3 install --upgrade numpy" did the trick.

I got exactly the same problem but "pip3 install --upgrade numpy" didn't fix it. Any ideas?

Edit:
I changed
sudo python3 /home/pi/pi-camera-stream-flask/main.py
to
python3 /home/pi/pi-camera-stream-flask/main.py
and now it works.

Sorry about that. If it didn't work then I don't know of any other solutions to the problem. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
