Could not initialize class org.tensorframes.impl.SupportedOperations

Inizia riproducendo il fallimento relativo a analyze in ExperimentalOperations.scala, in particolare alle righe 146-148, e ispeziona SupportedOperations e DebugRowOps, come indicato nello stack trace. Determina il problema di inizializzazione sottostante e verifica che la chiamata a analyze venga completata senza il NoClassDefFoundError.

Py4JJavaError: An error occurred while calling o162.analyze.
