Seaborn update

[Bachstelze]

The first plot in bert_example.ipynb had this FutureWarning:

Pass the following variables as keyword args: x, y. From version 0.12, the only valid positional argument will be `data`, and passing other arguments without an explicit keyword will result in an error or misinterpretation.

The future is now and this error is thrown:

TypeError: barplot() takes from 0 to 1 positional arguments but 2 positional arguments (and 1 keyword-only argument) were given

Adding the x and y keys fixed the error:

ax = sns.barplot(x=['his', 'her'], y=[float(predicted_target[his_id].detach()), float(predicted_target[her_id].detach())], linewidth=0, palette='Set1')

Also networkx changed from nx.from_numpy_matrix to nx.from_numpy_array.
