Way to speed up by omitting plot display, just saving the plot , when working with heavy notebook or big data.

Before update, I can save the figure without seeing it in jupyter notebook cell with code "plt.close()". This function is good for me working with big size notebook to write a analysis report. But, after update, this function is not working.
So I asked raphaelquast "Can I save the figure without seeing it in the cell ?"
He give me the solution using %%capture. This was a good solution.
