- Adds some ops for canned TF 2 Estimators
- Noops summary kernels so that the summary ops can be included in the graph but have no implementation on device
- Uses a custom namespace for double_convert to avoid conflicts with double_convert dependency in React Native
Custom namespacing the double_convert dependency isn't efficient but I couldn't work around dependency and I believe versioning issues with React Native and this was the simplest solution for a small amount of code.
