ThomasDelteil commented on issue #11275: Crash when trying to add two ndarrays on different GPUs URL: https://github.com/apache/incubator-mxnet/issues/11275#issuecomment-397197664 Shouldn't it return the same error than when trying to add from CPU ? Note that sometimes I get `Illegal Memory Access` error instead of invalid handle ===== edit Can someone explain to me why this is possible? I thought you cannot add across GPUs ? ``` train_loss [ [ 49.52454758] <NDArray 1 @gpu(0)>, [ 49.66656113] <NDArray 1 @gpu(1)>] train_loss[0] + train_loss[1] [ 99.1911087] <NDArray 1 @gpu(0)> train_loss[1] + train_loss[0] [ 99.1911087] <NDArray 1 @gpu(1)> ```
