How to use `seaborn` to distplot an array of double value in Python3.6?

I tried to use

to plot an array of double value but failed. Below is my source code:

>>> import seaborn as sns, numpy as np
>>> sns.set(); np.random.seed(0)
>>> x = np.random.randn(100)
>>> ax = sns.distplot(x)

Below is the error I got. I don't know what wrong with my code. Does anyone know the issue?

>>> ax = sns.distplot(x)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/anaconda/lib/python3.6/site-packages/seaborn/distributions.py", line 221, in distplot
kdeplot(a, vertical=vertical, ax=ax, color=kde_color, **kde_kws)

y = X[:m/2+1] + np.r_[0,X[m/2+1:],0]*1j
TypeError: slice indices must be integers or None or have an __index__ method

BTW, I am using python3.6.

Answer Source

This is caused by an old version of statsmodels and the problem is fixed in version 0.8.0. Upgrade it as described in https://github.com/mwaskom/seaborn/issues/1092

conda update statsmodels
