[IPython-user] dreload numpy issue

[belinda thom]

Hi,

I'm re-entering this problem that I reported earlier (http:// 
projects.scipy.org/pipermail/ipython-user/2007-January/003984.html)  
because the subject line was derived from an email that served a  
different purpose and I've not heard a reply. No hurry, but I would  
like it "on the books". :-)

I cannot dreload pylab or numpy, nor files that contain these  
imports. I've tried using the exclude= option in several ways to no  
avail, e.g. for file pyload.py, which contains an import pylab inside:

dreload(pyload)
dreload(pyload,exclude='pylab')
dreload(pyload,exclude=['pylab'])

all throw errors (appended)

It seems the default list should contain these files as well, since  
they (obviously?) mess up some kinds of hooks.

In [7]: dreload??
Source:
[snip]
def reload(module, exclude=['sys', '__builtin__', '__main__']):
     """Recursively reload all modules used in the given module.   
Optionally
     takes a list of modules to exclude from reloading.  The default  
exclude
     list contains sys, __main__, and __builtin__, to prevent, e.g.,  
resetting
     display, exception, and io hooks.
     """

In the very least, if this behavior is expected, then others might  
save some time if they find this post.

Thanks,
