Generate pdf from jupyter notebook without code

I have jupyter notebook which contains markdown, code and outputs (graphs). I want to generate pdf from this notebook.

I tried to hide code using html code which I get from here then I tried to download as pdf but again code shows up. But when I download as html it don't show any code but again when I tried to convert html to pdf it again shows code.

jupyter nbconvert --to pdf --TemplateExporter.exclude_input=True  my_notebook.ipynb
