说明：

• 介绍如何安装MXnet

步骤：

• MXNet 1.7安装

$ wget https://raw.githubusercontent.com/AastaNV/JEP/master/MXNET/autoinstall_mxnet.sh
$ sudo chmod +x autoinstall_mxnet.sh
$ ./autoinstall_mxnet.sh <Nano/TX1/TX2/Xavier>

# Python 2.7
sudo apt-get install -y git build-essential libatlas-base-dev libopencv-dev graphviz python-pip
sudo pip install mxnet-1.4.0-cp27-cp27mu-linux_aarch64.whl

# Python 3.6
sudo apt-get install -y git build-essential libatlas-base-dev libopencv-dev graphviz python3-pip
sudo pip install mxnet-1.4.0-cp36-cp36m-linux_aarch64.whl

测试：

• 新建文件vim hello_world.py

import mxnet as mx
import mxnet.ndarray as nd
a = nd.ones(shape=(2,3),dtype='int32',ctx=mx.gpu(0))
print(a.shape, a.dtype, a.size, a.context)

• 效果

$ python3 hello_world.py
(2, 3) <class 'numpy.int32'> 6 gpu(0)
