I just ran into this issue and managed to resolve it by removing the ampersand from the line that invokes `xdg-open`, i.e. I replaced `call system('xdg-open ' . shellescape(a:url).' &')`...

I think the issue might be that no validation data was passed to model.fit(). Try setting either `validation_data` or `validation_split`.

I also realize now that this doesn't update either the swig interface or the blocking API. I'm going to put some more thought into how it could be made to...
