Some deprecated code and IPythonViz import error

[KeremKurban]

Been trying to run the notebook but some arguments seem to be deprecated (i.e. nengo.PES(1e-3, **pre_synapse**=slow_tau) ) otherwise it does not work)

But could not solve the next issue:

from nengo_gui.ipython import IPythonViz IPythonViz(model,'configs/default.py.cfg')

out: ModuleNotFoundError: No module named 'nengo.utils.compat'

Full error:

Hi, thanks for letting me know! This notebook hasn't been updated in a while, and there's been a new major release of Nengo in the meantime. So, to provide a quick solution to getting it running, I've included a conda environment file here that you can use to include all necessary dependencies. Let me know if you run into any issues.
