Não consigo abrir jupyter notebook! Por favor me ajudem

[KKaelly]

Hi, very new to open cv/coding (only have some experience in R). I have been following the online instructions and up tp now everything seems to be going great! But when I try to run the code 'jupyter notebook' in comes up with the following (which I have no idea what it means).

It appears that you haven't managed installing jupyter with python 3.x successfully. I'd recommend talking to a local IT person to get the installation right.

Hope this helps.

Cheers!

I had the same issue. The problem is that by running
conda install -c menpo opencv3
you install opencv for python 2.7. This will downgrade your python version and jupyter notebook will not function anymore:

jupyter-console requires Python '>=3.5' but the running Python is 2.7.15

It should work if you install opencv for python 3.x. Re-do all the steps from the beginning (create new environment etc.) but type
conda install opencv
to install opencv for python 3.

It seems to work for me (just tried the example videos) and I hope it works for you, too.
