我试过安装不同版本的java，用不同的方式重新安装h2o，更新r，但是我还是不断地遇到同样的错误。我不确定是否是文件路径错误，因为路径名中有空格：

C:\Users\Augustine Antony

或者如果这是java的问题。
下面是错误消息

> h2o.init()

H2O is not running yet, starting it now...

Note:  In case of errors look at the following log files:
    C:\Users\Augustine Antony\AppData\Local\Temp\RtmpeCLF6t\file1ba8792a6dc0/h2o_Augustine_started_from_r.out
