Ran into this firing up interactive mode:

$ python

>>> import minimalmodbus
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/thoth/monitaur/daijin-modbus/minimalmodbus.py", line 4, in <module>
    instrument = minimalmodbus.Instrument('/dev/ttyUSB0', 1)  # port name, slave address (in decimal)
AttributeError: partially initialized module 'minimalmodbus' has no attribute 'Instrument' (most likely due to a circular import)

possibly my python is too new?

python -V                                                                                                              [8:12:41]

I'm working with python 3.7.4 without problems.

Do you have your custom file with name minimalmodbus.py and you try to import system library minimalmodbus? This can cause lot of problems. Just rename your file.
