How to avoid merging the Partial dependence plots

I am trying to plot objective function for the optimized neural network using plot_objective but the plots are getting merged. Is there anyway to fix this?

obtained plot

A similar question was asked here So, I tried:

plt.tight_layout()

It is bit helpful bu开发者_JAVA技巧t still there is merging like this plot_tight

I used this:

_ = plot_objective(result,n_points=12)

and

plt.tight_layout()
