when u say use 

Task.current_task()

 you for logging? which i’m guessing that the fastai binding should do right?

right, this is a fancy way to say, make sure the actual sub-process is initializing ClearML so all the automagic kicks in, since this is not "forked" but a whole new process, calling Task.current_task is the equivalent of calling Task.init with the same arguments (which you can also do, I'm not sure which one is more straight forward, wdyt?)
