This error happens whenever I'm using pdfminer. I also installed pdfminer-six

My code worked just fine until two days ago. It started to happen today when I tried to just run it again without any adjustment in the file

I'm assuming maybe it's the pdfminer's problem but there's no update about the module...

(I'm running this on my conda env)

Does anyone know what this error means? and how to fix it?

Answer 1

When I encountered this I used:

pip install chardet
