Nbdev #hide_output does not hide output

Hello,
I am building my own library and the development is going pretty good so far. However, I am stuck on an issue, I can’t seem to fix. My library has a dependency of nltk where I need to do

nltk.download('punkt')
nltk.download('stopwords')
nltk.download('averaged_perceptron_tagger')
nltk.download('wordnet')

I have to put this code in #export tag so that these lines get exported. I also put the #hide_output tag but that doesn’t seem to hide the output.

If I put the tag of #hide, the tests fail during CI. If I put #hide_output, it does not hide the output. The link to the library is over here. Functions | clean_plot (deven367.github.io)
Can anyone help me fix this? Thanks :slight_smile:
