My system is Ubuntu 16.04.
when I run code make -j4 USE_OPENCV=1 USE_BLAS=openblas USE_CUDA=1 USE_CUDA_PATH=/usr/local/cuda USE_CUDNN=1

I got the error

how can I solve this problem

[reminisce]

You need to install openblas. Please follow the steps here for building from source.
http://mxnet.incubator.apache.org/install/index.html
Try this
sudo apt-get install libopenblas-dev.
