Description of proposed changes
When
Figure.show(method="notebook")
is called but IPython is not installed, we raise theGMTError
exception, which is the base class for all GMT-related errors.Raising such a low-level, base exception is usually not good. Instead, we should raise
ImportError
exception in this case.
