# `events`

Event definitions for OCL evaluation loops.

Events emit in the following order:

```text
TrainBegin (once)
    TrainTaskBegin (for number of tasks)
        TrainBatchPredict
            TestBegin
            TestTaskBegin (for number of tasks)
                EvalBatchPredict
            TestTaskEnd
        TestEnd
    TrainTaskEnd
TrainEnd
```

| [`EvalBatchPredict`](capymoa.ocl.evaluation.events.EvalBatchPredict.md#capymoa.ocl.evaluation.events.EvalBatchPredict)   | After predicting on an evaluation batch, but before any updates.   |
