Addestrare un modello AutoML (API Vertex AI)

Questa pagina descrive come addestrare un modello AutoML utilizzando l'API Vertex AI.

Per informazioni sull'utilizzo di Google Cloud Console per l'addestramento di un modello AutoML, consulta Addestramento di un modello AutoML mediante Cloud Console.

Prima di iniziare

Prima di poter addestrare un modello, devi preparare i dati di addestramento e creare un set di dati.

Addestramento di un modello AutoML mediante l'API

Quando addestri un modello utilizzando l'API, crei un oggetto TrainingPipeline, specificando il set di dati che contiene i tuoi dati di addestramento.

Seleziona il tuo tipo di dati di seguito:

Prima di utilizzare uno qualsiasi dei dati della richiesta, effettua le seguenti sostituzioni:

  • LOCATION: area geografica in cui si trova il set di dati e viene creato un modello. Ad esempio us-central1.
  • PROJECT: il tuo ID progetto.
  • TRAININGPIPELINE_DISPLAYNAME: campo obbligatorio. Un nome visualizzato per la pipelinePipe training.
  • DATASET_ID: il numero ID del set di dati da utilizzare per l'addestramento.
  • fractionSplit: facoltativo. Uno dei numerosi possibili ML utilizza le opzioni di suddivisione per i dati. Per fractionSplit, i valori devono essere pari a 1. Ad esempio:
    • {"trainingFraction": "0.7","validationFraction": "0.15","testFraction": "0.15"}
  • MODEL_DISPLAYNAME*: un nome visualizzato per il modello caricato (creato) dalla TrainingPipeline.
  • MODEL_DESCRIPTION*: una descrizione del modello.
  • modelToUpload.labels*: qualsiasi insieme di coppie chiave-valore per organizzare i tuoi modelli. Ad esempio:
    • "env": "prod"
    • "tier": "backend"
  • MODELTYPE: il tipo di modello ospitato sul cloud da addestrare. Le opzioni sono:
    • CLOUD (valore predefinito)
  • NODE_HOUR_BUDGET: il costo effettivo dell'addestramento sarà uguale o inferiore a questo valore. Per i modelli Cloud, il budget deve essere: 8000 - 800.000 millisecondi (inclusi). Il valore predefinito è 192.000,il che rappresenta un giorno di durata, supponendo che vengano utilizzati 8 nodi.
  • PROJECT_NUMBER: numero del progetto del progetto

Rilevamento di oggetti

Seleziona la scheda relativa alla tua lingua o al tuo ambiente qui sotto:

REST &CMD LINE

Prima di utilizzare uno qualsiasi dei dati della richiesta, effettua le seguenti sostituzioni:

  • LOCATION: area geografica in cui si trova il set di dati e viene creato un modello. Ad esempio us-central1.
  • PROJECT: il tuo ID progetto.
  • TRAININGPIPELINE_DISPLAYNAME: campo obbligatorio. Un nome visualizzato per la pipelinePipe training.
  • DATASET_ID: il numero ID del set di dati da utilizzare per l'addestramento.
  • fractionSplit: facoltativo. Uno dei numerosi possibili ML utilizza le opzioni di suddivisione per i dati. Per fractionSplit, i valori devono essere pari a 1. Ad esempio:
    • {"trainingFraction": "0.7","validationFraction": "0.15","testFraction": "0.15"}
  • MODEL_DISPLAYNAME*: un nome visualizzato per il modello caricato (creato) dalla TrainingPipeline.
  • MODEL_DESCRIPTION*: una descrizione del modello.
  • modelToUpload.labels*: qualsiasi insieme di coppie chiave-valore per organizzare i tuoi modelli. Ad esempio:
    • "env": "prod"
    • "tier": "backend"
  • MODELTYPE: il tipo di modello ospitato sul cloud da addestrare. Le opzioni sono:
    • CLOUD-HIGH-ACCURACY-1: un modello ideale per l'utilizzo in Google Cloud, che non può essere esportato. Questo modello dovrebbe avere una latenza maggiore, ma dovrebbe anche avere una qualità della previsione superiore rispetto ad altri modelli cloud.
    • CLOUD-LOW-LATENCY-1: un modello ideale per l'utilizzo in Google Cloud, che non può essere esportato. Questo modello dovrebbe avere una bassa latenza, ma potrebbe avere una qualità di previsione inferiore rispetto ad altri modelli cloud.
  • NODE_HOUR_BUDGET: il costo effettivo dell'addestramento sarà uguale o inferiore a questo valore. Per i modelli Cloud, il budget deve essere compreso tra 20.000 e 900.000 millisecondi (incluse). Il valore predefinito è 216.000,che rappresenta un giorno di durata totale, supponendo che vengano utilizzati 9 nodi.
  • PROJECT_NUMBER: numero del progetto del progetto
