Correlation Dimension does not work.

[Simon-Linke]

The function cdim always raises an error (see below for the error message; I'm using Windows 10 and installed comsar 0.0.3 via pip). Is there a fast solution to this problem? Or is it possible to avoid that cdim being calculated when extracting a Timbre Track? (I usually don't need it)

I cannot read the actual error buried in this noise. Can you please reformat the message? Also, some context would be helpful. Could you post a minimal but complete code example that reproduces the error?

[Simon-Linke]

The error is produced as soon as I try to compute a TimbreTrack:

from comsar.tracks._timbre import TimbreTrack tt = TimbreTrack() a = tt.extract('Data\\Stimuli_wav\\1.wav')

I'm sorry, but I cannot reformat the message as the error message appears as it is, without any line breaks. But here is a reduced version shown in JupyterLab:

---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
ValueError: cdim_bader failed.


The above exception was the direct cause of the following exception:
