Typo: John said:
make build_osx105
Note the extra 'x'.
By the way John, in this particular case, I don't think the change
warrants a before/after example, because the before case is "it
doesn't run" :) The code today makes calls to Numeric routines like
typecode() that simply don't exist anymore, so it's totally broken:
In [1]: x = rand(512,3)
In [2]: ij = [(0,1),(1,2)]
In [3]: mlab.cohere_pairs(x,ij)

600 ind = range(0, numRows-NFFT+1, NFFT-noverlap)
601 numSlices = len(ind)

The fixes Ariel is sending are strictly confined to making the code
run again, by using the equivalent numpy calls:
In [1]: x = rand(512,3)
In [2]: ij = [(0,1),(1,2)]
In [3]: mlab.cohere_pairs(x,ij)

Ariel, if you are still struggling with the binary build, since your
changes are confined to a pure python file, you can submit the patch
by simply running:
- svn udpate
- modify in-place mlab.py with your version of cohere_pairs
- svn diff > mlab_cohere_pairs.diff
You may want to watch out for the fact that the docstring in your
version doesn't start with
u"""
This means the string is Unicode. It seems mpl has been unicode-ified
so it's best to fix this before you generate the diff. This is why
John encourages the diff to be made against HEAD, so these little
things can be easily spotted. By doing this, you'll notice small
changes in formatting you might not have meant to introduce, so it
lets you clean up the contribution before sending it so it really only
changes what you intended to.
Cheers,
f
