Any help?

Try instead:
pip install kivy
Worked for me on my Windows machine. Make sure pip is in the Path enviornment variable on your machine.

I am new to machine learning. Please suggest a solution

As error said - operation is not permitted. I'm Linux not Mac user - but it's probably because you try to do this without root privilages.
You can try sudo pip install coremltools. But generally speaking installing development libraries system-wide is not best practice.
You should definitely use virtualenv.

And it gives these traceback errors. I'm unable to figure out what these errors are and how to solve them. Please help. It works perfectly till collecting the packages but at the time of installing it throws errors.

If you're using Windows, the easiest way to install many of the numerically-oriented Python packages is to download one of wheels containing pre-compiled binaries from http://www.lfd.uci.edu/~gohlke/pythonlibs/, and install using pip:
pip install SomePackage-1.0-py2.py3-none-any.whl
Make sure to download the right wheel version (Python2 or Python3, 32 bit or 64 bit) for your Python installation.

Try python -m pip install matplotlib.
or
Open the cmd as administrator
then python -m pip install matplotlib

No module named flask in Microsoft Visual Studio 2013

When I run a new (Fresh creation without any modifications) Flask Web Project in Visual Studio it does not compile. I get an error "No module named flask". This makes no sense to me because it was a "Flask" project that I created and I didn't do anything to break it. Is it possible that Microsoft provides broken template for new Flask projects? I'm confused.
When I try to add a virtual environment I get the following log:
Value cannot be null.
