charlespnh opened a new issue, #35841: URL: https://github.com/apache/beam/issues/35841
### What would you like to happen? It seems like currently Beam's anomaly detection modules only supports numeric features, e.g. `beam.Row(f1=0.1, f2=0.2, ...)` - https://github.com/apache/beam/blob/master/sdks/python/apache_beam/ml/anomaly/detectors/pyod_adapter.py#L80 For use cases with vector embedding, e.g. `beam.Row(embedding=[0.1, 0.2, ...])`, then the pipeline will fail with the following error: ``` np_batch.append(np.fromiter(row, dtype=np.float64)) TypeError: float() argument must be a string or a real number, not 'list' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: setting an array element with a sequence. ``` ### Issue Priority Priority: 2 (default / most feature requests should be filed as P2) ### Issue Components - [ ] Component: Python SDK - [ ] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [ ] Component: IO connector - [ ] Component: Beam YAML - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Infrastructure - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
