tensorboardX/examples/demo_graph.py -> AssertionError: %1 : Tensor = onnx::Constant[value={2}]() has empty scope name

[vpapaioannou]

Describe the bug I try to run tensorboardX/examples/demo_graph.py for jupyter notebook (launched by anaconda navigator) and I get the error seen at Additional context.

I just copy paste the code to notebook from Github.

Minimal runnable code to reproduce the behavior class SimpleModel(nn.Module): def init(self): super(SimpleModel, self).init()

   def forward(self, x):
        return x * 2

model = SimpleModel() dummy_input = (torch.zeros(1, 2, 3),)

with SummaryWriter(comment='constantModel') as w: w.add_graph(model, dummy_input, True)

Environment Windows, command : conda list | findstr proto, tensor, torch torch -> 1.1.0 libprotobuf -> 3.7.1 protobuf -> 3.5.2 tensorboard -> 1.13.1 tensorboardX -> 1.4 tensorflow -> 1.13.1 tensorflow-base -> 1.13.1 tensorflow-estimator -> 1.13.0 tensorflow-gpu -> 1.13.1

tensorboardX v1.4 is old, please update.
