ImporteurRor: Der Name 'Client' kann nicht von 'Pinecone' (unbekannter Ort) importiert werden ⇐ Python

[Anonymous]

Das Problem mit diesem Code ist, dass ich nicht in der Lage bin, Client aus der Pnecone -Bibliothek zu importieren. Ich habe versucht, verschiedene Versionen zu deinstallieren und neu zu installieren, keine von ihnen hat gearbeitet. Ich habe es auch mit der Bibliothek pnecone-Client versucht, aber nichts davon funktioniert. Jeder Rat würde geschätzt.
