Answer 1

您可能想尝试不同版本的 Java 而不是 Weka 附带的版本，以排除这是罪魁祸首：

• 从 adoptium.net 下载 Java 11 的 ZIP 文件（不是 MSI！）并将其解压缩到某个位置，例如桌面上（通过使用 ZIP 文件，您不必成为管理员即可使用它） .

• 确定您刚刚提取的可执行文件

  java.exe

  的绝对路径，例如：

  C:\Users\MyUser\Desktop\jdk-11.0.18+10\bin\java.exe
  

• 确定Weka安装的绝对路径

  weka.jar

  ，例如：

  C:\Program Files\Weka-3-8-6\weka.jar
  

• 打开 Windows 命令提示符。

• 使用您刚刚确定的路径运行以下命令来启动 Weka（在路径周围使用 双引号以考虑路径中的潜在空间）：

  "JAVAEXE_PATH" -jar "WEKAJAR_PATH"
  

  使用上述路径转换为：

  "C:\Users\MyUser\Desktop\jdk-11.0.18+10\bin\java.exe" -jar "C:\Program Files\Weka-3-8-6\weka.jar"
  

如果不再慢了，那么Weka自带的Zulu Java很可能就是罪魁祸首。

如果没有，您将必须检查其他程序（例如防病毒程序）是否可能导致速度变慢。

我想我发现了一些东西：v

有人知道如何解决吗？我有与此相同的问题，我多次安装和卸载它，但我的 weka 仍然无法打开
