haimeh commented on issue #6629: Not enough information to get shape URL: https://github.com/apache/incubator-mxnet/issues/6629#issuecomment-321357117 @thirdwing @nnguyen24 If you replace the train.x and train.y array with: ``` # Generate testing data train.x = matrix(data = rexp(200, rate = 10), nrow = 120, ncol = 6380) train.y = matrix(data = rexp(200, rate = 10), nrow = 120, ncol = 320) # Reshape testing data train.array <- train.x dim(train.array) <-c(20,6,1,ncol(X)) ``` You can trigger the error. The test set is not necessary to recreate the error. I experienced the same error with my own fancy loss function. I got around it, in the end, by implementing the loss inside a modified mx.model.train function (right before backward pass) replacing the symbols with mx.nd operations. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
