Do you particularly want to use the master version of sympy from git? It's usually better to use the latest release (currently 1.7.1) unless you are planning to work on making changes to sympy itself.
You can install the latest release by running e.g "pip install sympy" (or "conda install sympy" if you are using Anaconda). If you do want to install the master version of sympy then you need to run "python setup.py install" (after "git clone").
