jasperDD commented on issue #14104: Error in mx.nd.internal.empty.array(shape, ctx) : [14:58:38] C:\Jenkins\workspace\mxnet\mxnet\src\storage\storage.cc:137: Compile with USE_CUDA=1 to enable GPU usage in R URL: https://github.com/apache/incubator-mxnet/issues/14104#issuecomment-462131508 I understood what the problem. I don't have Nvidia card, so i must use MXnet only CPU and not GPU like this model <- mx.model.FeedForward.create( X = train, eval.data = val, ctx = **mx.cpu()**, symbol = captcha_net, eval.metric = mx.metric.acc2, num.round = 10, learning.rate = 0.0001, momentum = 0.9, wd = 0.00001, batch.end.callback = mx.callback.log.train.metric(50), initializer = mx.init.Xavier(factor_type = "in", magnitude = 2.34), optimizer = "sgd", clip_gradient = 10 )
