我正在追赶h2o的MOJO和POJO模型格式.我可以用MOJO/POJO保存模型

h2o.download_mojo(model, path = "/media/somewhere/tmp") # ok
h2o.download_pojo(model, path = "/media/somewhere/tmp") # ok

与名称写入一个对象像mymodel.zip或mymodel.java到目录.

但是,我不清楚如何将它读回R中的服务器.我试过,

saved_model2 <- h2o.loadModel("/media/somewhere/tmp/mymodel.java") # not work
saved_model3 <- h2o.loadModel("/media/somewhere/tmp/mymodel.zip") # not work

但得到这样的错误信息,

ERROR: Unexpected HTTP Status code: 400 Bad Request (url = http://localhost:54321/99/Models.bin/)

java.lang.IllegalArgumentException
 [1] "java.lang.IllegalArgumentException: Missing magic number 0x1CED at stream start"  
....
Error in .h2o.doSafeREST(h2oRestApiVersion = h2oRestApiVersion, urlSuffix = page,  : 

ERROR MESSAGE:

Missing magic number 0x1CED at stream start

我在这里读到CUDA 6.5已经开始支持C++ 11:

但是当我编译下面的示例代码时,我得到了

$ nvcc -std = c ++ 11 cu-gcc11.cu -o test

nvcc警告:配置的主机编译器不支持-c ++ 11标志.标志将被忽略.

cu-gcc11.cu(7):错误:缺少显式类型(假设为"int")

我的设置:CUDA 6.5,g ++ 4.5,ubuntu 12.04

代码:

#include <cuda.h>
#include <iostream>

__host__ void test() {
  float a = 12.;
  double b = 3.;
  auto c = a * b;
  std::cout << c << std::endl;
}

int main()
{
  test();
  return 0;
}
