需要將CVS文件轉換爲arff文件的解決方案

Question

我是新手..！我需要加載一個CSV文件WEKA所以我用這個終端指令

java -cp /usr/share/java/weka.jar weka.core.converters.CSVLoader newfile.csv > miller.arff

和我recive一些象這樣的錯誤......

Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar ---Registering Weka Editors--- Trying to add database driver (JDBC): RmiJdbc.RJDriver - Error, not in CLASSPATH? Trying to add database driver (JDBC): jdbc.idbDriver - Error, not in CLASSPATH? Trying to add database driver (JDBC): org.gjt.mm.mysql.Driver - Error, not in CLASSPATH?

可能是什麼問題呢？ ？

在newfile.csv中檢查第40140行。它最有可能只包含7個值。
