When I type in the following,

brew tap homebrew/science

brew install opencv3 --with-contrib --withpython3

I get the errors

Warning: opencv: this formula has no --with-contrib option so it will be ignored!

Warning: opencv: this formula has no --with-python3 option so it will be ignored!

How might I fix this issue.

I am using Mac Sierra 10.12.16

maybe you should not insist on using homebrew (not supported at all from opencv), but just build from src, like anyone else does.

I followed their instructions. The commands are from that tutorial, but they do not have my error under the troubleshooting area.

Do you have python 3 installed?
