Received invalid argument(s): hold

[Xirailuyo]

I just installed IDTxl, and seem to be having trouble with the plot_network function. I may be missing a dependency, but I'm having trouble locating the problem. I have attached the error below. All the other functions in the demos seem to be working fine. I am using Ubuntu 20, cuda 11, and anaconda for environment and package management. Importing pylab and matplotlib do not resolve the issue. Thank you.

This bug is because of networkx and matplotlib. After the upgrade of these two libs, they remove the argument "hold." You can try to remove all "hold=True" from the file "visualise_graph.py"

Thanks @AlexMa123 for the pointer. We have updated calls to networkx in the current development branch (see 26be465). This will be released shortly. You can try the develop version if you want to use this feature immediately.
