Bug fixed in 11.2
I have a few GPU/CPU 'loaded' Linux boxes in my lab, used largely for rendering. I want to compare the new 11.1 Neural Network stuff to some Tensorflow things we do here. Of course, since I have all that iron back there I want to use it.
I don't want to have to actually walk all that way, and besides, they are headless (or head-impaired).
I haven't tried using remote kernels for anything other than
Parallel stuff in quite a while (like, 1990 or so, with a Cray). I've noticed that the 'Basic' settings in
Evaluation->Kernel Configuration Options ... don't work so I had to go and manually get a connection to happen, thanks to this answer I was able to cobble something together that works.
Things that contain
Dynamic content aren't happy. To wit, here's an example, first evaluated on the Local machine, then evaluated on the remote -
NetChain isn't formatted when returning from the remote kernel. The error -
A GridBox with an invalid first argument was encountered. The first argument to GridBox must be a rectangular matrix (nested list).
makes a little bit of sense, spelunking the thing returned -
suggests to me that there are things that don't get faithfully interpreted by the front-end's kernel when they come back from the remote.
This wouldn't be a problem, other than I would like to run the learning remotely and observe the progress on the front end. This is further reinforced to me by the fact that, if I cut-and-paste the 'red-box' output from the remote-kernel'd notebook into a local-kernel notebook, it renders properly.
Any thoughts on how to get the local notebook kernel to jibe with the output of the remote kernel?
Edit: Fixed in 11.2
Developer`$DisableInteractivity = Truemakes the graphs show up w/o interactivity, of course. $\endgroup$
