A small bug in protocol

[hbredin]

Can you please provide me with a simple code sample where this creates a bug?

[yinruiqing]

item={}
item['uri'] = 'fileName'
template = "/to/path/wav/{uri}.wav"
template.format(item)

or

preprocessors = {'wav': '/Users/yin/projects/corpora/etape/wav／{uri}.wav'}
database = get_database('Etape', preprocessors=preprocessors)
protocol = database.get_protocol('SpeakerDiarization','Debug')
for item in protocol.train():
    for X, y in generator.from_file(item):
        break

In python 2.7 and python 3.5
raise
KeyError

But we can set preprocessor to be a function to solve this problem

[hbredin]

OK. I see. There is a bug indeed for string preprocessors. I will fix it.

In the meantime, here is what you can do:

• Create the configuration file ~/.pyannote/db.yml:

$ cat ~/.pyannote/db.yml
Etape: /Users/yin/projects/corpora/etape/wav{uri}.wav

• Use the new FileFinder utility that will automagically use this configuration file to find the wav files:

from pyannote.database.util import FileFinder
preprocessors = {'wav': FileFinder()}
database = get_database('Etape', preprocessors=preprocessors)

Have a look at my ~/.pyannote/db.yml to learn more about the possible syntax.

I just released pyannote.database 0.11.2 that fixes this bug.
It also improves the documentation and describes this FileFinder thing in the README.md file.
