Could not initialize class org.tensorframes.impl.SupportedOperations

Comienza reproduciendo el fallo alrededor de analyze en ExperimentalOperations.scala, especialmente en las líneas 146-148, e inspecciona SupportedOperations y DebugRowOps, tal como se nombran en el stack trace. Determina el fallo de inicialización subyacente y verifica que la llamada a analyze se complete sin el NoClassDefFoundError.
