Block until all pending writes operations on current NDArray are finished.
Block until all pending writes operations on current NDArray are finished. This function will return when all the pending writes to the current NDArray finishes. There can still be pending read going on when the function returns.
NDArray object in mxnet. NDArray is basic ndarray/Tensor like data structure in mxnet.
NOTE: NDArray is stored in native memory. Use NDArray in a try-with-resources() construct or a [[org.apache.mxnet.ResourceScope]] in a try-with-resource to have them automatically disposed. You can explicitly control the lifetime of NDArray by calling dispose manually. Failure to do this will result in leaking native memory.
