Hello. Installation was accomplished with no errors whatsoever until the testing part, when importing cv 2, it shows that there is no module named cv2. How does one fix this? Thank you :)

[kardibeats]

can i do that with breaks? i mean i have work and i don't want my raspberry turned on how a long period of time.. im about to finish the make -j$(nproc)

[WTFhowdIdie]

The following error comes up after typing everything out at the 7:00 mark:

"The source directory "/home/pi/opencv' does not appear to contain CMakeLists.txt"

Why? I followed everything in the video but all attempts to troubleshoot it just lead to other errors. Everything was fine up to that point.

on the rpi zero W it took me over 6 hours to download and compile.

[paulsmith]

looks like I did everything correct up to the last line in Terminal. I entered cv2._version_ I got the following. Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: module 'cv2' has no attribute '_version_'
>>>
Any idea on what I did wrong? thanks
