1 year ago Hi @pedro-acunha , thanks for raising this - sorry to hear you've been having trouble running. I'm not reproducing this in my setup, and the fact that it is a hang rather than an error + traceback makes it a bit harder to work out what's going on.
It would be very helpful if you could try getting a bit more info on the issue. First, you could try running the isolated code block that should do the same thing as the example notebook:
import matplotlib.pyplot as plt
from strauss.sonification import Sonification
from strauss.sources import Objects
from strauss import channels
from strauss.score import Score
from strauss.generator import Synthesizer
import IPython.display as ipd
import os
from scipy.interpolate import interp1d
import numpy as np
# seed the randoms...
np.random.seed(0)
# construct arrays of size N for x and y...
N = 300
x = np.linspace(0,1,N)
y = np.zeros(N)
# define a Gaussian function...
gauss = lambda x, m, s: np.exp(-(x-m)**2/s)
# place some randomised gaussians...
for i in range(10):
a,b,c = np.random.random(3)
y += gauss(x, b, 1e-3*c) * a ** 3
# now add some noise and normalise
y += np.random.random(N) * y.mean()
y /= y.max()*1.2
y += 0.15
plt.plot(x,y)
plt.ylabel('Some dependent Variable')
plt.xlabel('Some independent Variable')
plt.savefig("test_plot.png")
# specify audio system (e.g. mono, stereo, 5.1, ...)
system = "stereo"
# length of the sonification in s
length = 15.
# set up synth and turn on LP filter
generator = Synthesizer()
generator.load_preset('pitch_mapper')
generator.preset_details('pitch_mapper')
notes = [["A2"]]
score = Score(notes, length)
data = {'pitch':1.,
'time_evo':x,
'phi':(x*0.5+0.25) % 1,
'theta':0.5,
'pitch_shift':y}
# set up source
sources = Objects(data.keys())
sources.fromdict(data)
sources.apply_mapping_functions()
soni = Sonification(score, sources, generator, system)
soni.render()
soni.save_stereo('test_audio.wav')you could save this script as e.g. strauss_test.py and try running this in the terminal - does it still still hang? If it runs ok you should get the plot and audio output as .png and .wav files respectively
if it runs OK in this case it's likely some kind of problem with the jupyter environment (perhaps how you have it set up). If it still hangs, could try sending it a keyboard interrupt (ctrl+c on your system) to hopefully get a traceback of where the code is when it hangs. If that doesn't work either we can look into using the faulthandler module to dig a bit further.

I followed the instructions to install strauss as provided in the github page, using the following commands:
git clone https://github.com/james-trayford/strauss.git strausscd strausspip install .When running the examples in strauss/examples, I am unable to successfully run the cell with Sonification function. It gets stuck with this output:
This can also be seen below, for the SonifyingData1D example:
I did try to run with two different machines (similar setups), but the problem remains in both.
I am running strauss in a machine with:
