example does not work

[xiaokebubu]

I installed cochlea-master on Windows 8 with Anaconda(python2.7 64-bit). It works successfully in jupyter notebook to processing a generated sound as shown in usage website. Then I am trying to run the example by using a sound file but there is something wrong.

C:\Users\Alice\Desktop\cochlea-master\cochlea-master\scripts>python run_zilany2014 --hsr=100 --msr=75 --lsr=25 --cf=1000 --species=human --seed=0 --dbspl=60 tone.wav
Processing tone.wav

tools.py", line 2203, in resample
Y = zeros(newshape, 'D')
TypeError: 'float' object cannot be interpreted as an index

I tried to transform the datatype into int

waves.py
100: new_signal = dsp.resample(signal, len(signal)*new_fs/fs)
replaced by: new_signal = dsp.resample(signal, int(len(signal)*new_fs/fs))

but then there were some other asserting problems.
(like "assert sound.ndim == 1". I checked my data, in which the sound.ndim=2).

I am new to python and I 'm not sure why this may be. Could you help me with it?

Hi! Thanks for the bug report in the resample(). I've fixed it in the repository of thorns.

but then there were some other asserting problems. (like "assert sound.ndim == 1". I checked my data, in which the sound.ndim=2). I am new to python and I 'm not sure why this may be. Could you help me with it?

So run_zilany2014() is a model of a single ear, i.e., it expects one dimensional signal as input. I guess that you are using a wave file with 2 channels (stereo). If you convert it to mono, it should work.

Problem solved! Thanks very much for your help : ).
