As this discussion indicates there has been a switch from numpy 0.9.8 to numpy 1.0b of how to handle backward compatibility. Instead of importing old names a new sub-package numpy.oldnumeric was created. This mechanism is incomplete in the sense that there are still some backward-compatible items in numpy such as defaults on the axis keyword for functions versus methods and you still have to make the changes that convertcode.py makes to the code to get it to work. I'm wondering about whether or not some additional effort should be placed in numpy.oldnumeric so that replacing Numeric with numpy.oldnumeric actually gives no compatibility issues (i.e. the only thing you have to change is replace imports with new names). In other words a simple array sub-class could be created that mimics the old Numeric array and the old functions could be created as well with the same arguments. The very same thing could be done with numarray. This would make conversion almost trivial. Then, the convertcode script could be improved to make all the changes that would take a oldnumeric-based module to a more modern numpy-based module. A similar numarray script could be developed as well. What do people think? Is it worth it? This could be a coding-sprint effort at SciPy. -Travis ------------------------------------------------------------------------- Take Surveys. Earn Cash.
