Orca breaks with toolz>=0.11, because tz.compatibility.zip is depreciated

[MaxBo]

if toolz>=0.11 is installed, an error is raised in orca.py in line 940,

labels_map = dict(tz.concatv( tz.compatibility.zip(names[:offset], names[:offset]), tz.compatibility.zip(names[offset:], expressions)))
because tz.compatibility.zip does is not supported any more from toolz>=0.11.
With tools==0.10 it still works.

You could either switch to the standard library zip instead of
tz.compatibility.zip , or if you need this for compability reasons with python 2, pin the toolz-version to 0.10.

Hi @MaxBo, thanks for catching this! It should be fixed now in the toolz-patch branch, and we'll put out a release as soon as we do a little more testing.

Here's the code on the toolz side, for future reference: https://github.com/pytoolz/toolz/blob/master/toolz/compatibility.py

Incidentally, it looks like toolz.compatibility is just supposed to raise a DeprecationWarning beginning in v0.11, which is what happens on my Mac. But in one of our Linux environments it raised an error, likely the same as what's described above -- an AttributeError on importing tlz.compatibility. The fix I implemented is to switch to the standard library zip, which should solve things either way.

I've encountered the same issue. Hope this fix gets pushed in soon. Thanks Sam!
