Error API Cloud Video Intelligence - Requested model could not be loaded

Inizia da test.py e dalla documentazione collegata sulla classificazione video in streaming di Video Intelligence, quindi esamina l'esempio di StreamingVideoIntelligenceServiceClient e la relativa configurazione del modello. Riproduci la risposta 'Requested model could not be loaded' e verifica i requisiti documentati per il modello AutoML e l'endpoint. Il lavoro è completato quando l'esempio e la documentazione indicano chiaramente la configurazione necessaria oppure correggono l'utilizzo mostrato.

Describe the issue

https://cloud.google.com/video-intelligence/docs/streaming/video-classification

I am conducting a series of tests on AutoML, using the code provided in the official documentation, and I am encountering an issue. After training the model with VortexAI, completing the process, and retrieving the Model ID, the Python APIs consistently return 'Requested model could not be loaded.' Honestly, the demos are poorly written, and the exceptions in the code are very implicit. Some demos don't work, and you have to make corrections in certain areas to get them to function properly.

python3 ./test.py
"Requested model could not be loaded."

The model was specifically trained for Video Intelligence in the VortexAI section and, in turn, did not function correctly. In the documentation, it's not clear whether the model necessarily requires an Endpoint. Both the code and the documentation have a comprehension issue.
