we need wheels for python 3.14, it's falling back to numpy which requires all the tools to compile from source

opencv doesnt work with python 3.14

Inizia esaminando la toolchain CI automatizzata del repository e i job dei wheel per le versioni di Python, quindi riproduci il fallimento dell'installazione di Windows con Python 3.14 mostrato nel report. Il lavoro è completato quando vengono prodotti e pubblicati wheel compatibili per Python 3.14, in modo che l'installazione non ricorra più alla compilazione di NumPy dal codice sorgente.
