Provide odd length kernels

[NicolasGensollen]

In release 1.6 of Scipy, the function sepfir2d only accepts odd length arrays for hrow and hcol (see this PR).

The Travis failure seems unrelated...

The Travis failure seems unrelated...

Yes it is unrelated and is also currently breaking #342
I can't reproduce this failure on my machine yet, I'll have to look a little bit more into it

Yes, this is indeed a separate issue. On #342 it only comes up with the continuous-integration/travis-ci/pr check but not with continuous-integration/travis-ci/push check. Here also it is on continuous-integration/travis-ci/pr.

Based on Travis docs (see the section on 'Double builds') it seems to me that the PR check is done on the merge of the PR and the main branch. So maybe something is up with the main branch? Not very sure...

[NicolasGensollen]

Is there something preventing this to be merged?

[man-shu]

The fix has passed all the checks on this PR, but I just committed the same fix on #342 and one of the checks failed again.

On the other hand, on #342 only, without having made these changes (in commit 9378e0d) the same check passed!

@man-shu I think it was a Travis issue. I restarted the failed check and it passes now.

[bthirion]

Merging, then !

[bthirion]

thx to all of you !

[man-shu]

Great!
