bug in cm.py

Vincent_Schut · December 6, 2007, 12:00pm

Hi,

there is a bug in cm.py (svn): it references npy (first time: line 58),
but npy is never imported.

Cheers,
VS.

Michael_Droettboom1 · December 6, 2007, 12:47pm

Thanks. I have corrected this in SVN.

Cheers,
Mike

Thanks.
However, now I get a different error:

Can you send your script that triggers this bug? I wasn't the author of this code, so I don't know how to get that path to execute -- but I'm happy to work through your example until it's working.

(I suspect the intention here was "m, n = x.shape[:2]", but I can't test it.)

Cheers,
Mike

Hmm, that's a bit hard, it's not really what one would call a
self-contained example...

the bug triggers when I load a rgb numpy float array with imshow (only
with floats, not with ints).

After some thought and trial, it's simple: these lines already trigger
the error:

···

#======================
import pylab, numpy

rgbFloat = numpy.random.random((100,100,3))
pylab.imshow(rgbFloat)
pylab.show()
#======================

Hope that helps!

Thanks, that helps a lot.

It seems to be working now -- I've committed this in r4643.

Mike,

Thanks for fixing those two errors that I introduced in 4374. I'm sorry that I evidently did not test that code path, or even inspect it carefully.
