[Numpy-discussion] Supporting both NumPy and Numeric versions of a module (original) (raw)

Dear Mary, I suggest using numpy and at the boundaries use numpy.asarray(yourinput), which will be a quick way to view the data as a numpy array, regardless of its original type. Otherwise, you could look at the matplotlib distribution to see how it's done to really support multiple array packages simultaneously.

Hi all,

We are getting ready to release some Python software that supports both NumPy and Numeric. As we have it now, if somebody wanted to use our software with NumPY, they would have to download the binary distribution that was built with NumPy and install that. Otherwise, they have to download the binary distribution that was built with Numeric and install that. We are using Python's distutils, and I'm trying to figure out if there's a way in which I can have both distributions installed to one package directory, and then the init.py file would try to figure out which one to import on behalf of the user (i.e. it would try to figure out if the user had already imported NumPy, and if so, import the NumPy version of the module; otherwise, it will import the Numeric version of the module). This is turning out to be a bigger pain than I expected, so I'm turning to this group to see if anybody has a better idea, or should I just give up and release these two distributions separately? Thanks, --Mary
