Missing requirement: packaging

[jorolf]

After using pip to install this package on Ubuntu 20.04:

$ pip3 install PyLMI-SDP
Collecting PyLMI-SDP
  Using cached PyLMI_SDP-1.1-py3-none-any.whl (10 kB)
Requirement already satisfied: sympy in /home/jorolf/.local/lib/python3.8/site-packages (from PyLMI-SDP) (1.11.1)
Requirement already satisfied: mpmath>=0.19 in /home/jorolf/.local/lib/python3.8/site-packages (from sympy->PyLMI-SDP) (1.3.0)
Installing collected packages: PyLMI-SDP
Successfully installed PyLMI-SDP-1.1

I get the following error message after importing the module:

---------------------------------------------------------------------------

ModuleNotFoundError: No module named 'packaging'

Which can be fixed by also installing the packaging package, although the "correct" solution would probably be to add it as a dependency for this package...

Thanks for reporting. packaging is now added to the dependencies.
