Plot several graphs in pytorch tensorboard


I am training a dynamic neural network, meaning that each epoch I tweak the architecture and get a different computational graph.
I want to plot the graph for each epoch using tensorboard, but when I use SummaryWriter.add_graph() at the end of each epoch it simply overwrites the previous one.

Any ideas how to plot several graphs using pytorch + tensorboard? It seems achievable as each graph has a “tag” but I found no option to change this tag to plot several of them.
