Hello, I am trying to run the example from readthedocs which is:
from scipy import stats
data = stats.gamma.rvs(2, loc=1.5, scale=2, size=100000)
from fitter import Fitter
f = Fitter(data, timeout=3000, distributions=['gamma', 'rayleigh', 'uniform']) #Increasing time out time
f.fit()
f.summary()
and I am getting:
WARNING:root:SKIPPED uniform distribution (taking more than 3000 seconds)
WARNING:root:SKIPPED rayleigh distribution (taking more than 3000 seconds)
/home/miguel/.local/lib/python3.9/site-packages/scipy/stats/_continuous_distns.py:4530: IntegrationWarning: The integral is probably divergent, or slowly convergent.
intg = integrate.quad(f, -xi, np.pi/2, **intg_kwargs)[0]
WARNING:root:SKIPPED gamma distribution (taking more than 3000 seconds)
WARNING:fitter.fitter:uniform was not fitted. no parameters available
WARNING:fitter.fitter:rayleigh was not fitted. no parameters available
WARNING:fitter.fitter:gamma was not fitted. no parameters available
WARNING:matplotlib.legend:No handles with labels found to put in legend.
My version of fitter from pip is 1.3.0...
Am I doing something wrong? The example from the readthedocs should work in principle right?
Also, I was thinking that there might a bug with the timeout parameter? no matter how much time I give it, it always returns SKIPPED x distribution (taking more than y seconds), where y can be a very large number.

@miguelcarcamov
I ran you your data and it gives me result without any skipping. I was using fitter 1.3.0
Out[6]:
sumsquare_error aic bic kl_div
gamma 0.000073 1494.092341 -2.103890e+06 inf
rayleigh 0.018802 2858.246376 -1.548651e+06 inf
uniform 0.278573 711.116338 -1.279077e+06 inf
@MigueLesPaul@miguelcarcamov I'm sorry about that. This is strange.
On version 1.3.0 and 1.4.0 I got the answer in a fraction of a second repeatedly.
It will be difficult to debug this on my side. Please make sure scipy is up-to-date. Try with 10,000 sample then 1,000 and see it converges but I'm still puzzled that it does not work. I see that you are under python3.9; maybe there is an issue with python3.9 not sure. I have added 3.9 to the continuous integration to see whether this work at least on github.
