i cant install, when i try to install always "retrying", should i download antivirus? should i download minecraft? should i buy new graphic card? :(

[MrXIndependent]

so good! Although I had to figure out that I need to install virtualenv and it's purpose from the comment section. Thank you so much, you rock. I had issues before trying to install opencv-python on my PC without a virtualenv and even though it would install, it would never find cv2 when I typed import cv2.

[komronyusupov]

what to do here is such a mistak??
Traceback (most recent call last):
File "faces.py", line 10, in <module>
recognizer =
AttributeError: module 'cv2.cv2' has no attribute 'face'

[prajvalp]

even after installing virtualenv it says the term is not recognized

[shitozeruel]

I got the same error as @flipsiclesticks 'virtualenv command not found'

[OmarAhmed-rgii]

Thanks, worked perfect with me on Python 3.7.1

[ryanswick]

what is ive installed the v.env and type testopencv and get errors that its not recognized

[khalednasr]

Thanks a lot. I have installed open cv with extra modules. However, after i type python, the shell doesn't allow me to write anything at all, so i can not write "import cv2". how to solve that?

When I enter virtualenv testopencv it says that it does't recognise virtualenv. I made a Dev folder in users and did the cd command first. None of the commands I have tried to install virtualenv with have worked. I have tried with python 3.0 and 3.7. This is the first time I have tried to do anything with python and I have no idea what I'm doing. Please help.

virtualenv : The term 'virtualenv' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
