ModuleNotFoundError: No module named 'chardet'

Hi, I'm using pdftotree on Ubuntu with python3.6. I first installed python3 toolkit, then pdftotree. So when I import pdftotree, this error appeared
ModuleNotFoundError: No module named 'chardet'
So I think I should install chardet but I want to know which version should I install to be in sync with the application. Thank you for your feedback

Hey guys, this problem is provided by pdfminer on the utils script and exactly this part:
if six.PY3:
import chardet # For str encoding detection in Py3
unicode = str
so, i installed chardet==3.0.4 and the problem is solved.
