Selective operator build workflow for multiple models in a single runtime environment #18104
Description
🚀 The feature, motivation and pitch
ExecuTorch provides several mechanisms for selective operator compilation (e.g. EXECUTORCH_SELECT_OPS_MODEL, EXECUTORCH_SELECT_OPS_YAML). These workflows appear to be primarily designed around building a runtime for a single model.
In deployments where a single runtime must support multiple models, each model may require a different set of operators. Currently this typically requires manually extracting and merging operator sets from multiple models before building.
It would be able to provide multiple models or YAML files as input for operator extraction, or to document a recommended workflow for building a runtime that supports multiple models.
This would simplify common scenarios where one ExecuTorch runtime needs to execute several models.
Alternatives
Have been using a solution by merging multiple YAML files outside of Executorch, so that is a usable workaround.
