In line 155 in runner.py we can't rely on __name__ because a functools.partial object has no attribute __name__.

~/Work/induced_gap_B_field/adaptive/runner.py in _run()
    353                     except Exception as e:
    354                         raise RuntimeError(
--> 355                             'An error occured while evaluating '
    356                             f'"{self.learner.function.__name__}({x})". '
    357                             'See the top traceback for details.'

AttributeError: 'functools.partial' object has no attribute '__name__'

Maybe it should just be:

                    except Exception as e:
                        raise RuntimeError(
                            'An error occured while evaluating '
                            f'"learner.function({x})". '
                            'See the top traceback for details.'

that's a nice solution! Much cleaner than what I was thinking
