[No such file or directory error] when running documentation examples about muda HOT 7 CLOSED

Yikes, that's the least helpful error message I've ever seen.

The first thing I can think of: do you have rubberband installed and in your path?

from muda.

Thank you so much Brian! Rubberband was not installed as you said. Thank you for pointing that out for me. Now the same code returns the following:

---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)
<ipython-input-6-ba2efbb97ebe> in <module>()
----> 1 for i, jam_out in pitch.transform(jams_obj):
      2     muda.save('output_{:02d}.wav'.format(i),
      3               'output_{:02d}.jams'.format(i),
      4                jam_out)

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/jams/core.pyc in __getitem__(self, key)
    262     def __getitem__(self, key):
    263         """Dict-style interface"""
--> 264         return self.__dict__[key]
    265 
    266     def __setattr__(self, name, value):

KeyError: 0

I could only guess am I using the generator in a wrong way?

from muda.

Oh, I think maybe that iterator should be wrapped as enumerate(pitch.transform(jams_obj))?

(Currently on mobile, otherwise would test it myself)

from muda.

You are right! I should have spot that as well. Just FYI, I was lazily copying the code from the documentation. I just added enumerate() and it worked! Thank you!

from muda.

Glad it's working, and sorry for the incorrect example code! I'll fix it when I'm back on a real machine.

Alternately, a PR would be greatly appreciated if you want to take a stab at it.

Thanks for pointing this out!

from muda.

No problem, I will do a PR later!

I'm closing this one out -- I think the original cause of this report is better handled within pyrubberband.
