Plot mistake

[karakol15]

There is a problem in the visualization part. When I am trying to plot the graph in the example, I see the following mistake:

---

TypeError Traceback (most recent call last)
in
12 ice_plot(ice_df, frac_to_plot=0.1,
13 color_by='x3', cmap=PuOr,
---> 14 ax=ice_ax);
15
16 ice_ax.set_xlabel('$X_2$');

C:\ProgramData\Anaconda3\lib\site-packages\pycebox\ice.py in ice_plot(ice_data, frac_to_plot, plot_points, point_kwargs, x_quantile, plot_pdp, centered, centered_quantile, color_by, cmap, ax, pdp_kwargs, **kwargs)
128 if frac_to_plot < 1.:
129 n_cols = ice_data.shape[1]
--> 130 icols = np.random.choice(n_cols, size=frac_to_plot * n_cols, replace=False)
131 plot_ice_data = ice_data.iloc[:, icols]
132 else:

mtrand.pyx in mtrand.RandomState.choice()

TypeError: 'float' object cannot be interpreted as an integer

To be precise, I may be getting the error in a different place:

[SunnyW4869]

supposed to be solved by modified line as follow #27
icols = np.random.choice(n_cols, size=int(frac_to_plot * n_cols), replace=False)

but for me it still doesn't work, showed the same error information even the log showed the modified line with int() in ice.py

Please check

Update

Restarting the kernel did the trick
Modifying line 130 as described in #27 is the solution for this issue.
