Hi, I'm new to Sage too, but I faced this exact same error on a different file recently. Basically, my understanding is that sometimes Sage is unable to use a package that is installed on the local system and is not available within its directory. Check the following path (or equivalent) in your sage directory: local/lib/python2.7/site-packages/ If this does not have a sympy folder, the python used by Sage does not have sympy (and can't use the one that may be installed on your system) which is why it gives that error. In that case, try the following: 1. Download sympy <https://github.com/sympy/sympy/releases/tag/sympy-1.0> and unzip. 2. Go inside directory and install using sage - "sage --python setup.py install" This worked for me.
