Answer 1

You're trying to change your system Python. That's why it says [Errno 1] Operation not permitted. To avoid messing up system libraries, you need to create separate Python virtual environment. This is how to do it:

1. Upgrade pip:

   pip install --upgrade pip
   

2. Install virtual environment.

   pip install –U virtualenv
   

3. Create new virtual environment:

   cd ~
   virtualenv coreml
   

   This creates folder ~/coreml/ and a local copy of Python, pip and all other stuff you need for work.

4. To activate virtual environment:

   source coreml/bin/activate
   

   Now you see in your terminal (coreml) prepends your user name.

5. In newly created virtual environment:

   pip install -U coremltools
   

6. Check that library was installed successfully:

   python
   import coremltools
   

   There should not be any error messages.

7. To deactivate virtual environment run:

   deactivate
   

Note: Never run pip with sudo. If you need sudo, 99% chance you're doing something wrong.

Answer 2

Is their a specific reason, that you downloaded the .whl-file?

You cloud try to install directly from PyPI with:

pip install -U coremltools

This is the recommended way as shown in the link, you already posted.
