UnboundLocalError: local variable 'mutation' referenced before assignment #44

Hi Jake, When running example code as beflow: `import numpy as np import pandas as pd

from matplotlib import pyplot as plt

from bartpy.sklearnmodel import SklearnModel

x = np.random.normal(0, 0.5, size=1000) X = pd.DataFrame({"x": x}) y = 2 x + 4 np.power(x, 3) plt.scatter(x, y)

model = SklearnModel(n_jobs=1)

model.fit(X, y) plt.scatter(x, model.predict()) plt.scatter(x, y)`

I got the following error: 0%| | 0/200 [00:00<?, ?it/s]Starting burn Traceback (most recent call last):

Do you know where the problem is? Thank you. xiangwei

duhd1993 commented 5 years ago

Same here.

duhd1993 commented 5 years ago

The ReadOneTrees branch seems working.

JakeColtman commented 5 years ago

Hi, Thanks for trying it out and raising an issue :) I'd pretty strongly recommend working off the ReadOneTrees branch rather than master. I'm going to do some final checks and then merge the changes back in.

CoteDave commented 5 years ago

Same problem here !

The ReadOneTrees branch seems working.

Thank you!

como se una la rama ReadOneTrees alguien me ayuda porfavor, tengo el mismo problema de: "local variable 'mutation' referenced before assignment"

Hi, I got the same problem, have you solved it?

WilsonAntony-171060 commented 4 years ago

Si amigo lo resolvi. La solucion esta en que deberas instalar la libreria desde la rama que te indica el autor de la libreria
