@fchollet, @qlzh727 Thanks for the quick reply @gbaned, unfortunately i looked in the repos of keras-team and the type `DistributedDatasetInterface` is nowhere mentioned. I have opened a new issue in keras. Or do is there a specific build pipeline how `tensorflow/python/keras/engine/` is created
This closes the issue #61204
The datatype has been moved, I assume the function `_is_distributed_dataset` has not been tested.
This simple code change resolves the import issue.
