   ## Description
   I have installed the Anaconda3 and installed the mxnet-cu90 by pip but the training speed is very slow
   
   and I find that ,the data reading speed is much slow , when reading image data and decoding the binary data by imdecode , the GPU usage is 30%, I guess that, the speed bottleneck of the speed is data reading.
   
   multi-gpu and single gpu are the same slow
