some-guy1 edited a comment 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-419603828 Ok this is confusing living heck out of me. I ran your code above and iter$value() results in the dimensions I would expect. Hence, this appears correct. BUT, I tried again to simply run only my code below ``` train_iter <- mx.io.CSVIter( data_csv = "A.csv", data_shape = c(3, 3, 1), label_csv = "A.csv", label_shape = c(3, 3, 1), batch_size = 1 ) train_iter$reset() train_iter$iter.next() train_iter$value() ``` and I still only get one value in the label. I am expecting $label to be identical to $data ``` $label [1] 1.373546 ``` Now instead if I run: ``` train_iter <- mx.io.CSVIter( data_csv = "A.csv", data_shape = c(3, 3, 1), label_csv = "A.csv", label_shape = c(3, 1, 3), batch_size = 1 ) train_iter$reset() train_iter$iter.next() train_iter$value() ``` I get ``` $`data` , , 1, 1 [,1] [,2] [,3] [1,] 1.1643714 2.689276 2.152658 [2,] 0.8696243 1.527834 1.233204 [3,] 2.1957829 2.738622 1.815747 $label , , 1, 1 [,1] [1,] 1.1643714 [2,] 0.8696243 [3,] 2.1957829 , , 2, 1 [,1] [1,] 2.689276 [2,] 1.527834 [3,] 2.738622 , , 3, 1 [,1] [1,] 2.152658 [2,] 1.233204 [3,] 1.815747 ``` Is it possible that the label axis is rotated relative to the data axis? Are we supposed to transpose the label axis until is matches the data axis?
