Hi I am new to this group and this topic is kind of old but maybe the problem is still there.
I had the same issue and I got it working in this way: open file setup.py and, at the end, replace

install_requires=[
'pyserial',
'PyQt5',
'numpy',
'scipy'
],

with

install_requires=[
'pyserial',
'PyQt5 <= 5.14.0',
'numpy',
'scipy'
],

It worked for me, I am running Ubuntu 18.04.4 LTS
