No device assignments were active

When I use on windows10, just run a complex model ,it failed, the error like this
No device assignments were active during op 'Embedding-Token/embedding_lookup/Identity' creation., others are used correctly.

Hi @xiaomengxin123, we'll need more information to diagnose the issue. What kind of model are you trying to run? Can you repro the error while using the vanilla TensorFlow 1.15 repo with a GPU device? It would help if you could share a script to repro the issue.

Thanks and I see,the detail is

, Maybe it was caused by tensorflow_core and not model .
