I'm having trouble downloading the slycot library using terminal via pip

So I'm trying to download slycot via pip and I keep getting errors. To be completely honest I'm not totally familiar with terminal prompts and how all that works. Here is what I'm getting when I run, sudo -H pip3 install slycot
Here is what terminal publishes with that command:

The project does not specify a build backend, and pip cannot fall back to setuptools without 'setuptools>=40.8.0' and 'wheel'.

Any help would be appreciated.

You have another error with the installation of slycot, you have a dependency on skbuild.
In order to fix it check this site that gives you the compiled binaries to the skbuild package and try again [and maybe cmake as well]
Try this
pip install scikit-build; pip install cmake
You can read here for more details and ways to make this work.

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.

pip install census for census.gov API

I am very new to python, and I am trying to speak with the census.gov API to find the population of several zipcodes. I was able to get my API key, and I am using this python wrapper: https://github.com/datamade/census. I was able to install pip using the sudo easy_install pip command. Here's an example of the output when I run it again:

Your user doesn't have write permissions on /System/Library. Either run pip install from the root user or use pip install -u to install the library to your own directory instead of the system one.

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
