Unable to open rfswarm.py (GUI / Server)

Thanks for the feedback, made the suggested change and able to launch the RF Swarm GUI.

Firstly, Thanks for trying rfswarm out.

This is an interesting error, hopefully we can figure it out.

I was initially going to ask if you had tkinter installed, but from reading through the stack trace it's obvious you do, so I guess we need to find out which version?

from a python3.7 prompt can you run the following commands to check your tkinter version:

>>> import tkinter
>>> tkinter.TkVersion

For reference this is what I get:

DavesMBP:rfswarm dave$ python3
Python 3.7.4 (default, Jul  9 2019, 18:13:23) 
[Clang 10.0.1 (clang-1001.0.46.4)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
>>> tkinter.TkVersion
8.5
>>> 

In the meantime I'll start checking if there is any known issues around this between between 8.5 and 8.6.

I think I found the problem
This line:
self.pln_graph.pack(fill="both", expand=True)
Is not actually needed, as the line below does the same thing and they are conflicting:
self.pln_graph.grid(column=0, row=planrow, sticky="nsew")

It didn't error for me, so I missed that, it looks like the tkinter on your machine is being more fussy, so I would still like to know which version you have.

In the meantime, can you just comment out or remove line 577 in "rfswarm.py" and see if that gets you working?

I have checked the code and it seems this is the only place I used .pack, so this should be the only line you need to change, I will also push a bugfix for this.
