h2o.download_pojo(
  model,
  path = NULL,
  getjar = NULL,
  get_jar = TRUE,
  jar_name = ""
)

Arguments

model	An H2OModel
path	The path to the directory to store the POJO (no trailing slash). If NULL, then print to to console. The file name will be a compilable java file name.
getjar	(DEPRECATED) Whether to also download the h2o-genmodel.jar file needed to compile the POJO. This argument is now called `get_jar`.
get_jar	Whether to also download the h2o-genmodel.jar file needed to compile the POJO
jar_name	Custom name of genmodel jar.

Value

If path is NULL, then pretty print the POJO to the console. Otherwise save it to the specified directory and return POJO file name.

Examples

# NOT RUN {
library(h2o)
h <- h2o.init()
fr <- as.h2o(iris)
my_model <- h2o.gbm(x = 1:4, y = 5, training_frame = fr)

h2o.download_pojo(my_model)  # print the model to screen
# h2o.download_pojo(my_model, getwd())  # save the POJO and jar file to the current working
#                                         directory, NOT RUN
# h2o.download_pojo(my_model, getwd(), get_jar = FALSE )  # save only the POJO to the current
#                                                           working directory, NOT RUN
h2o.download_pojo(my_model, getwd())  # save to the current working directory
# }
