I’m attempting to generate an embedding visualization using PyTorch 1.1.0. I’m following the example in the documentation 3 but running into an issue. When I try loaded the “Projector” component in Tensorboard, the backend returns a 500 and logs the following error:
I0605 22:51:01.434675 140375100487424 _internal.py:97] ::ffff:172.17.13.114 - - [05/Jun/2019 22:51:01] "GET /data/plugin/projector/runs HTTP/1.1" 500 -

Anyone got any pointers on how to resolve this? I’m not sure why Tensorboard is looking for a checkpoint.
Output of pip list|grep tensor is:
