I'm trying to install openCV 4.0 from the following link:

https://www.alatortsev.com/2018/11/21/installing-opencv-4-0-on-raspberry-pi-3-b/

 

This complete command:

https://pastebin.com/JPuTprVf

 

Not work, but i have not errors during compiling.

The problem is:

 

1)  apt-get  install libjasper-dev libpng12-dev   (Not Found)
2) But I seem to remember that even with Raspberry and raspbian there was the same error.

 

pip3 install numpy scipy

3) I don't find a file anywhere cv2.so

 

Can you help me ?
I'm a beginner with Linux.

For this, I think you simply has to do "apt-get install python-setuptools".

This is because you're mixing python2 and python3 !

If numpy is using python3, then your need to do "apt-get install python3-setuptools" ...

Were you able to "ping pypi.org" ?

Maybe this server is down ...

Ok, now download, but it crashes.

Also after reboot.
Can I clean and restart ?
