jeremiedb commented on issue #12428: [R] mx.io.CSVIter not loading labels in version 1.3.0 URL: https://github.com/apache/incubator-mxnet/issues/12428#issuecomment-419599628 Can you confirm whether the following is working: ``` cran <- getOption("repos") cran["dmlc"] <- "https://apache-mxnet.s3-accelerate.dualstack.amazonaws.com/R/CRAN/"; options(repos = cran) install.packages("mxnet") library(data.table) library(mxnet) data <- matrix(rnorm(9*5), ncol = 9) fwrite(x = as.data.table(data), file = "data.csv", col.names = F) labels <- matrix(rnorm(9*5), ncol = 9) fwrite(x = as.data.table(data), file = "label.csv", col.names = F) iter <- mx.io.CSVIter(data_csv = "data.csv", data_shape = c(9), label_csv = "label.csv", label_shape = c(3,1,3), batch.size = 2) iter$reset() iter$iter.next() iter$value() ``` This has been run on Windows 10 and R 3.5.1 and worked fine. From the error message provided `symbol$infer.shape(list(...))`, issue seems more related to the network definition.
