Installing Open CV
The provided instructions are incorrect.
The correct command is
conda install -c conda-forge opencv
conda install --help you will see that the -c flag tells conda which channel to install the package from.
The command provided in the course erroneously uses the environment (called capstone) as the second argument of the install command.
PackagesNotFoundError: The following packages are not available from current channels: -capstone
This error is evidence to the user that the package the program is attempting to install is '-capstone', rather than opencv
I have raised this with support who were most unhelpful.
