My neural network classifier reports "Unexpected CURL error"

While defining my classifier, the following error message appears, no idea what to do with CURL error and installed R package bit64, but not moving forward what should I do with this:

classifier = h2o.deeplearning(y = 'Exited',
                          training_frame = as.h2o(training_set),
                          activation = 'Rectifier',
                          hidden = c(6,6),
                          epochs = 100,
                          train_samples_per_iteration = -2)

This is the error:

Error in .h2o.doSafeREST(h2oRestApiVersion = h2oRestApiVersion, urlSuffix = urlSuffix, : Unexpected CURL error: couldn't open file "C:/Users/Felhasználó/AppData/Local/Temp/RtmpInvPFf/file25246dec7784.csv"

In addition: Warning message:

In use.package("data.table") : data.table cannot be used without R package bit64 version 0.9.7 or higher. Please upgrade to take advantage of data.table speedups.

  1. install.packages ('h2o')
  2. install.packages ('bit64')
  3. install.packages ('data.table')
  4. data.table :: update.dev.pkg ()
  5. updated my JDK java;
  6. go to program files, java and delete the old java folder;
  7. restart my computer.

Try to Install bit 64 RStudio from a different repertory

install.packages('bit64', repos = "https://cran.rstudio.com")

Happy Helping!!

Regarding the warning message, I think it's some problem at H2O. I updated the R version and the data.table and the warning still rising.

data.table version:

> packageVersion("data.table")
[1] ‘1.12.8’

My R version:

> R.version
