Hiding code when exporting jupyter notebook to pdf

hide_code_pdf.md

From here: https://ga7g08.github.io/2015/06/25/ipython-nbconvert-latex-template-to-hide-code/

1. Create a file named hidecode.tplx in the directory of your notebook with the following content:

((*- extends 'article.tplx' -*))

((* block input_group *))
    ((*- if cell.metadata.get('nbconvert', {}).get('show_code', False) -*))
        ((( super() )))
    ((*- endif -*))
((* endblock input_group *))

2. Export your jupyter notebook to pdf using the template:

$ jupyter nbconvert --to pdf --template hidecode Notebook.ipynb

Hello,
It's not working for me. Code is still there in pdf doc.

Hello,
The problem is that you need to place hidecode.tplx in the same directory as article.tplx

Working with me, thanks
