Hi, @tBuLi , thank you for the package. Just as https://stackoverflow.com/questions/55580926/how-to-extend-the-number-of-symfit-parameters-arbitrarily-in-python, I would like to wrap this package for api: model: (dict of) sympy expression(s). e.g; a * x+ b...

Models don't have a __repr__ method

1

Models currently don't have a repr method, which makes debugging needlessly difficult in some cases. See e.g. https://travis-ci.org/github/tBuLi/symfit/jobs/702160446#L329
