[MLIR]Tensorflow Graph IR Dev Status

Hi there,
I am really interested in Tensorflow MLIR, and hope to create custom dialects from Tensorflow’s existing dialects.
I found that recently there is a TensorFlow Graph IR , it seems quite exciting. May I ask what is its def status by now?

Does it support basic runtime? I mean, could I use it for actually run by now? I am going to use it for optimizing ResNet training, is it ok now?

Besides, Is there any dev discussion group for now? Like PyTorch’s developer group in slack.


The Graph IR is fairly recent, and enabled by default in Grappler for a bit more than a month now.
We’re ramping up on this this quarter to provide more natural extension point and helpers for transformations on this.
