I cannot comment on Tensorbord, since I was just using it for a short period of time when tensorflow was released.
At the moment I’m using Visdom 19 to visualize the loss and possible prediction images.
It’s maybe not as beautiful / organized as Tensorboard, but to be honest, I still don’t know what I’m supposed to see in e.g. the Tensorboard histograms. 
Have a look at the visdom examples 40. They work with tensors as well as numpy arrays.
