Could not import data reader: unidectools

I am trying to create a script to call UniDec

import unidec
file_name="210112__solveig_AN0.raw.intensityThreshold1000.PPM10.errTolDecimalPlace3.Time20210128191052.MS.txt"
folder="F:/SK/"
eng=unidec.UniDec()
eng.open_file(file_name, folder)
eng.process_data()
eng.run_unidec(silent=True)
eng.pick_peaks()

but getting following error

must mention that i did a brute force-installation git clone https://github.com/michaelmarty/UniDec followed by move unidec* folder/py scripts to lib, probably that is the issue? What is the proper way to install? I did try

pip install pymzml 
pip install natsort 
pip install unidec

without success...
