The initial 'import numpy' loads a huge number of modules, even when I don't need them. Python 2.5 (r25:51918, Sep 19 2006, 08:49:13) [GCC 4.0.1 (Apple Computer, Inc. build 5341)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> len(sys.modules) 28 >>> import numpy >>> len(sys.modules) 256 >>> len([s for s in sorted(sys.modules) if 'numpy' in s]) 127 >>> numpy.__version__ '1.1.0' >>> As a result, I assume that's the reason my program's startup cost is quite high.

(I could use the array module or ctypes, but figured numpy is more useful for downstream code.) Why does numpy/__init__.py need to import all of these other modules and submodules? Any chance of cutting down on the number, in order to improve startup costs?
