我在 Rstudio 中运行 h2o 包,将 Tibble 转换为 h2o 时出现错误。
下面是我的代码
#Augment Time Series Signature
PO_Data_aug = PO_Data %>%
tk_augment_timeseries_signature()
PO_Data_aug
# Split into training, validation and test sets
train_tbl = PO_Data_aug %>% filter(Date <= '2017-12-29')
valid_tbl = PO_Data_aug %>% filter(Date>'2017-12-29'& Date <='2018-03-31')
test_tbl = PO_Data_aug %>% filter(Date > '2018-03-31')
str(train_tbl)
train_tbl$month.lbl<-as.character(train_tbl$month.lbl)
h2o.init() # Fire up h2o
##hex
train_h2o = as.h2o(train_tbl)
valid_h2o = as.h2o(valid_tbl)
test_h2o = as.h2o(test_tbl)
