Add support for Python 3 about audio_to_midi_melodia HOT 8 OPEN

It doesn't seem to work with Python3:

Loading audio...
Extracting melody f0 with MELODIA...
Converting Hz to MIDI notes...
Traceback (most recent call last):

    if p_prev > 0:
TypeError: '>' not supported between instances of 'NoneType' and 'int'

from audio_to_midi_melodia.

This specific error is described in #5. Fixing this issue seems straight forward, full python 3 support might require a few more changes. I'll have time to look into python 3 support in about 1 month. In the meanwhile, the easiest solution is to create a python 2.7 environment (e.g. using miniconda) and run the script from within this environment. Thanks in advance for your patience!

I changed the initialisation of p_prev (about line 107) to
p_prev = 0

from audio_to_midi_melodia.

I just want to add, there are two instances of p_prev you need to change. Line 126, and 107. Otherwise you get the error specified here

The codes sound, no pun intended and it's honestly amazing how it works with such a newer version of python so easily. I wouldn't abandon this project, it has a LOT of potential for DJs, Parody makers, and samplers like me alike.

I have the same question.
We also need python3 support !

from audio_to_midi_melodia.

What is broken with Python 3? I've just used it.

from audio_to_midi_melodia.

I fixed it as follow.
change
notes.append((onset_sec, duration_sec, p_prev))
to
notes.append((onset_sec, duration_sec, int(p_prev)))

from audio_to_midi_melodia.

Great code Justin 👍 & Great fix guys !
Set p_prev = 0 at line 107
Replace p_prev by int(p_prev) at lines 121 & 133 and it just works fine in Python 3 !! Awesome result !!
