A new stsci bug. I can't import scipy.stsci.image $ python >>> import scipy >>> import scipy.stsci >>> import scipy.stsci.image Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib64/python2.5/site-packages/scipy/stsci/image/__init__.py", line 2, in <module> from _image import * File "/usr/lib64/python2.5/site-packages/scipy/stsci/image/_image.py", line 2, in <module> import convolve ImportError: No module named convolve >>> scipy.stsci provides convolve, but it seems the import sentences in _image.py aren't correct
that looks like an upstream relevant bug. If you can get the import calls sorted out and send a patch in to me I'm incorporate it and send it upstream if its still necessary in scipy trunk. -jef
Created attachment 324072 [details] Stsci import patch Well, I have just started learning python and I don't quite understand the magic behind import. Anyway, I have found two ways of fixing the problem, either use full paths in the imports: import scipy.stsci.convolve as convolve or use relative imports: from .. import convolve this last one only works in python 2.5 though I have found another problem, a sentence with a.type(), where a is a numpy array. I have changed it by a.dtype
great I'll take a look at that patch and poke upstream about what they think of it. -jef
This bug isn't completely fixed in scipy-0.7.0-0.1.b1.fc10 This code fails: import scipy.stsci.image as im import numpy a = numpy.zeros((4,4)) im.translate(a, 1, 1) With this traceback: /usr/lib64/python2.5/site-packages/scipy/stsci/image/_image.pyc in translate(a, sdx, sdy, output, mode, cval) 51 b = np.rot90(a, rotation) 52 c = _correlate.Shift2d(b, int(dx), int(dy), ---> 53 mode=convolve.pix_modes[mode]) 54 d = _translate(c, dx % 1, dy % 1, output, mode, cval) 55 if output is not None: NameError: global name 'convolve' is not defined
And if you fix the previous error, you get the following: import scipy.stsci.image as im import numpy a = numpy.zeros((4,4)) im.translate(a, 1, 1) /usr/lib64/python2.5/site-packages/scipy/stsci/image/_image.py in translate(a, sdx, sdy, output, mode, cval) 54 d = _translate(c, dx % 1, dy % 1, output, mode, cval) 55 if output is not None: 56 output._copyFrom(np.rot90(output, -rotation%4)) 57 else: ---> 58 return np.rot90(d, -rotation % 4).astype(a.type()) AttributeError: 'numpy.ndarray' object has no attribute 'type'

0.7 was released a couple of weeks ago. If I build packages of that release will you test them for me. I hate applying a patch if I can move from a beta release to the final release and get it fixed. -jef
Yeah, I will test the packages
Freshly built 0.7 release rpms can be found from the appropriate architecture links here: http://koji.fedoraproject.org/koji/taskinfo?taskID=1205853 Please download and test these packages. If the scipy.stsci.image implementation still needs to be patched, let me know and I can try to drive that patch upstream as well. -jef
I've tested the package and it's still broken in the same place. The patch will be probably valid
patched scipy binarys now available http://koji.fedoraproject.org/koji/taskinfo?taskID=1212116 Please test these and if they pass your initial testing I'll push these to updates-testing repository. -jef
Seems to work, please push the update
