Ich versuche, ein Pandas Dataframe als Heatmap zu visualisieren, und bekomme seltsame Fehler mit allen Plotfunktionen Ich versuche es mit dem DataFrame-Objekt und DataFrame.values
Array und nichts Änderungen). Ich verstehe nicht, was der Grund dafür sein könnte. Dies ist der Datenrahmen:Typ Fehler bei der Visualisierung Pandas Dataframe als Heatmap

Also, es ist eine Art von Typ Problem ist, aber ich kann nicht sehen, wo es kommt von. Ich habe versucht, sowohl int

Werte in die DF
setzen, aber nichts ändert sich.
