Https: (Optional) Set this to TRUE to use https instead of http. Proxy: (Optional) A character string specifying the proxy path. This call can result in path issues when there is no “root” (for example, with a Windows network drive) because the config file reader searches up to “root.” When there is no “root”, the path to search will continue to expand, eventually result in an error. When h2o.init() is specified, a call to a config reader method is invoked. Ignore_config: (Optional) This option allows you to specify whether to perform processing of a. Strict_version_check: (Optional) Setting this to FALSE is unsupported and should only be done when advised by technical support. Ice_root: (Optional) A directory to handle object spillage. Append the letter m or M to indicate megabytes, or g or G to indicate gigabytes. This value must a multiple of 1024 greater than 2MB. Min_mem_size: (Optional) A character string specifying the minimum size, in bytes, of the memory allocation pool to H2O. This amount depends on the Java version, but it will generally be 25% of the machine’s physical memory. Note: If max_mem_size is not defined, then the amount of memory that H2O allocates will be determined by the default memory of the Java Virtual Machine (JVM). This value must be a multiple of 1024 greater than 2MB. Max_mem_size: (Optional) A character string specifying the maximum size, in bytes, of the memory allocation pool to H2O. The range for this option is 1MB to 99999MB. The file is rolled over after the specifized size has been reached. Max_log_file_size: Maximum size of INFO and DEBUG log files. License: (Optional) A character string value specifying the full path of the license file. This is used mainly for error checking and debugging purposes. ![]() This defaults to FALSE, so the executable will only be downloaded if it does not already exist in the H2O R library resources directory at h2o/java/h2o.jar.Įnable_assertions: (Optional) A logical value indicating whether H2O should be launched with assertions enabled. If an existing connection is detected, R does not start H2O.įorceDL: (Optional) A logical value indicating whether to force download of the H2O executable. This is only possible if ip = "localhost" or ip = "127.0.0.1". ![]() StartH2O: (Optional) A logical value indicating whether to try to start H2O from R if no connection with H2O is detected. Ip: The IP address of the server where H2O is running. ![]() If you start H2O locally outside of R or start H2O on Hadoop, the nthreads parameter is not applicable. Nthreads: This launches H2O using all available CPUs and is only applicable if you launch H2O locally using R. Note that in most cases, simply using h2o.init() is all that a user is required to do. This method accepts the following options. Use the h2o.init() method to initialize H2O. Saving, Loading, Downloading, and Uploading Models.
