Hi,
I downloaded&installed matplotlib 0.87.7 and other binary packages from
pythonmac.org for my new Intel Mac Pro. Then I downloaded and compiled the
latest scipy package. My collection of packages runs ok otherwise but there
seems to be something wrong with pylab/masked array behavior.
This works on my older installations (g5):
import matplotlib
matplotlib.use("TkAgg")
from pylab import *
from MA import *
#import MA
a=arange(100)
a.shape=(5,20)
a=swapaxes(a,0,1)
m=array([1,2,3],mask=[0,1,0])
#m=MA.array([1,2,3],mask=[0,1,0])
On my Intel Mac Pro, I get:
File "test.py", line 12, in ?
a=swapaxes(a,0,1)
File
"/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/numpy/core/fromnumeric.py",
line 106, in swapaxes
return _wrapit(a, 'swapaxes', axis1, axis2)
File
"/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/numpy/core/fromnumeric.py",
line 39, in _wrapit
result = getattr(asarray(obj),method)(*args, **kwds)
File
"/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/numpy/core/numeric.py",
line 132, in asarray
return array(a, dtype, copy=False, order=order)
ValueError: object __array__ method not producing an array
There seems to be some kind of name space conflict. The line
'a=swapaxes(a,0,1)' works as expected without 'from MA import *'. If I do
'import MA' and use MA.array etc for all operations with masked arrays
everything seems to work fine.
Any ideas where the conflict might be coming from?
