machine-learning - Tibble を h2o hex ファイルに変換中にエラーが発生する

Question

Rstudio で h2o パッケージを実行しています。Tibble を h2o に変換中にエラーが発生します。

以下は私のコードです

#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)
