Riprodurre il malfunzionamento usando il file allegato Select-2-objects-that-are-the-same-shape-7.json e tracciare l’accesso al dizionario da ObjectDetectionMetrics.ImageIoU, passando per GenerateIOUDic, fino alla riga 24 di LocalObjectDetectionMetricManager.cs. Controllare il flusso circostante in LocalObjectDetectionExperiment.cs alla riga 133 e in AutoMLEngine.cs alla riga 212. Il lavoro è completato quando il percorso di addestramento per il rilevamento degli oggetti non genera più un’eccezione di chiave mancante per questo input.

Scritto dal modello di indicizzazione a partire dal testo della issue.
