Recommendations mentioned in How to hide one specific cell (input or output) in IPython Notebook? don't work.
On Windows I do the following
jupyter nbconvert a.ipynb --TagRemovePreprocessor.remove_cell_tags="{'remove_cell'}"
but get an error
traitlets.traitlets.TraitError: The 'remove_cell_tags' trait of a TagRemovePreprocessor instance must be a set, but a value of type 'unicode' (i.e. u"{'remove_cell'}") was specified.
I also tried '{"remove_cell"}'
I am using nbconvert 5.4.0
Any ideas how to do this?
