As showcased in the recent wwdc regarding action classifier can one use tfrecord files as testing and training data to create a model?

Answered by Frameworks Engineer in 616664022

The action classifier cannot operate directly on TFRecord data. Instead, you can use either the original video files, or keypoints (previously extracted from video files) and stored as a MLDataTable, JSON, or CSV file. See this API reference for some more details: https://developer.apple.com/documentation/createml/mlactionclassifier/datasource

If you use the MLActionClassifier CreateML framework API, it has 5 types of data source supported. You may convert your tfrecord data to one of these formats as the input for training.
