See this plot_objective:
It was obtained by:
fig=plt.figure(num="HPO_plot_objective",figsize=(10,10))
plot_objective(result=optimize_result,n_points=n_calls)
the num_boost_round (on the left), and the eta (at the bottom, first column), is hidden by the margin. How to fix that?
I tried to play with margins in this way, but there is no effect
fig=plt.figure(num="HPO_plot_objective",figsize=(10,10))
plot_objective(result=optimize_result,n_points=n_calls)
plt.margins(1.0,1.0)
plt.savefig(f"results/plot_objective.png")
