Weka 3.8 Paket-Manager nicht funktioniert

Question

Ich versuche, den Paket-Manager von Tools tab zu öffnen und ich erhalte den folgenden Fehler:

C:\Users\user\wekafiles\repCache\MultiObjectiveEvolutionaryFuzzyClassifier\versions.txt (The system cannot find the path specified) 
    java.io.FileInputStream.open0(Native Method)

A problem has occurred whilst trying to get all package information. Trying a cache refresh... 
Refresh in progress. Please wait... 

dann lädt es das Standard-Paket-Manager:

[DefaultPackageManager] downloaded 13 KB 
[DefaultPackageManager] downloaded 16 KB 
[DefaultPackageManager] downloaded 28 KB 
[DefaultPackageManager] downloaded 50 KB 
[DefaultPackageManager] downloaded 67 KB 
[DefaultPackageManager] downloaded 75 KB 
...[DefaultPackageManager] downloaded 1666 KB 

und Ausgänge der gleiche Fehler erneut.

Anmerkung: Datei versions.txt richtig in C:\Users\user\wekafiles\repCache\MultiObjectiveEvolutionaryFuzzyClassifier Verzeichnis platziert

Was könnte falsch sein?

Answer 1

In der Tat existiert das Verzeichnis in Ihrem Dateisystem MultiObje c TiveEvolutionaryFuzzyClassifier ohne ein 'c'. Ändern Sie es selbst, Sie werden es gut funktionieren :)
