## MindSpore介绍
|
||||
|
||||
MindSpore是一种适用于端边云场景的新型开源深度学习训练/推理框架。
|
||||
MindSpore提供了友好的设计和高效的执行，旨在提升数据科学家和算法工程师的开发体验，并为Ascend AI处理器提供原生支持，以及软硬件协同优化。
|
||||
|
||||
|
||||
同时，MindSpore作为全球AI开源社区，致力于进一步开发和丰富AI软硬件应用生态。
|
||||
|
||||

||||
|
||||
<img src="docs/MindSpore-architecture.png" alt="MindSpore Architecture" width="600"/>
|
||||
|
||||
欲了解更多详情，请查看我们的[总体架构](https://www.mindspore.cn/docs/zh-CN/master/architecture.html)。
|
||||
|
||||
### 自动微分
|
||||
|
||||
当前主流深度学习框架中有三种自动微分技术：
|
||||
|
||||
- **基于静态计算图的转换**：编译时将网络转换为静态数据流图，将链式法则应用于数据流图，实现自动微分。
|
||||
- **基于动态计算图的转换**：记录算子过载正向执行时网络的运行轨迹，对动态生成的数据流图应用链式法则，实现自动微分。
|
||||
- **基于源码的转换**：该技术是从功能编程框架演进而来，以即时编译（Just-in-time Compilation，JIT）的形式对中间表达式（程序在编译过程中的表达式）进行自动差分转换，支持复杂的控制流场景、高阶函数和闭包。
|
||||
|
||||
TensorFlow早期采用的是静态计算图，PyTorch采用的是动态计算图。静态映射可以利用静态编译技术来优化网络性能，但是构建网络或调试网络非常复杂。动态图的使用非常方便，但很难实现性能的极限优化。
|
||||
|
||||
MindSpore找到了另一种方法，即基于源代码转换的自动微分。一方面，它支持自动控制流的自动微分，因此像PyTorch这样的模型构建非常方便。另一方面，MindSpore可以对神经网络进行静态编译优化，以获得更好的性能。
|
||||
|
||||
<img src="docs/Automatic-differentiation.png" alt="Automatic Differentiation" width="600"/>
|
||||
|
||||
MindSpore自动微分的实现可以理解为程序本身的符号微分。MindSpore IR是一个函数中间表达式，它与基础代数中的复合函数具有直观的对应关系。复合函数的公式由任意可推导的基础函数组成。MindSpore IR中的每个原语操作都可以对应基础代数中的基本功能，从而可以建立更复杂的流控制。
|
||||
|
||||
### 自动并行
|
||||
|
||||
MindSpore自动并行的目的是构建数据并行、模型并行和混合并行相结合的训练方法。该方法能够自动选择开销最小的模型切分策略，实现自动分布并行训练。
|
||||
|
||||
<img src="docs/Automatic-parallel.png" alt="Automatic Parallel" width="600"/>
|
||||
|
||||
目前MindSpore采用的是算子切分的细粒度并行策略，即图中的每个算子被切分为一个集群，完成并行操作。在此期间的切分策略可能非常复杂，但是作为一名Python开发者，您无需关注底层实现，只要顶层API计算是有效的即可。
|
||||
|
||||
## 安装
|
||||
|
||||
### 二进制文件
|
||||
|
||||
MindSpore提供跨多个后端的构建选项：
|
||||
|
||||
| 硬件平台 | 操作系统 | 状态 |
|
||||
| :------------ | :-------------- | :--- |
|
||||
| Ascend 910 | Ubuntu-x86 | ✔️ |
|
||||
| | EulerOS-x86 | ✔️ |
|
||||
| | EulerOS-aarch64 | ✔️ |
|
||||
| GPU CUDA 10.1 | Ubuntu-x86 | ✔️ |
|
||||
| CPU | Ubuntu-x86 | ✔️ |
|
||||
| | Windows-x86 | ✔️ |
|
||||
|
||||
使用`pip`命令安装，以`CPU`和`Ubuntu-x86`build版本为例：
|
||||
|
||||
1. 请从[MindSpore下载页面](https://www.mindspore.cn/versions)下载并安装whl包。
|
||||
|
||||
```
|
||||
pip install https://ms-release.obs.cn-north-4.myhuaweicloud.com/0.6.0-beta/MindSpore/cpu/ubuntu_x86/mindspore-0.6.0-cp37-cp37m-linux_x86_64.whl
|
||||
```
|
||||
|
||||
2. 执行以下命令，验证安装结果。
|
||||
|
||||
```python
|
||||
import numpy as np
|
||||
import mindspore.context as context
|
||||
import mindspore.nn as nn
|
||||
from mindspore import Tensor
|
||||
from mindspore.ops import operations as P
|
||||
|
||||
context.set_context(mode=context.GRAPH_MODE, device_target="CPU")
|
||||
|
||||
class Mul(nn.Cell):
|
||||
def __init__(self):
|
||||
super(Mul, self).__init__()
|
||||
self.mul = P.Mul()
|
||||
|
||||
def construct(self, x, y):
|
||||
return self.mul(x, y)
|
||||
|
||||
x = Tensor(np.array([1.0, 2.0, 3.0]).astype(np.float32))
|
||||
y = Tensor(np.array([4.0, 5.0, 6.0]).astype(np.float32))
|
||||
|
||||
mul = Mul()
|
||||
print(mul(x, y))
|
||||
```
|
||||
```

### Docker镜像
|
||||
|
||||
MindSpore的Docker镜像托管在[Docker Hub](https://hub.docker.com/r/mindspore)上。
|
||||
目前容器化构建选项支持情况如下：

|
||||
|
||||
> **注意：** 不建议从源头构建GPU `devel` Docker镜像后直接安装whl包。我们强烈建议您在GPU `runtime` Docker镜像中传输并安装whl包。
|
||||
|
||||
* CPU
|
||||
|
||||
对于`CPU`后端，可以直接使用以下命令获取并运行最新的稳定镜像：
|
||||
```
|
||||
docker pull mindspore/mindspore-cpu:0.6.0-beta
|
||||
docker run -it mindspore/mindspore-cpu:0.6.0-beta /bin/bash
|
||||
```
|
||||
|
||||
* GPU
|
||||
|
||||
对于`GPU`后端，请确保`nvidia-container-toolkit`已经提前安装，以下是`Ubuntu`用户安装指南：
|
||||
```
|
||||
DISTRIBUTION=$(. /etc/os-release; echo $ID$VERSION_ID)
|
||||
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | apt-key add -
|
||||
curl -s -L https://nvidia.github.io/nvidia-docker/$DISTRIBUTION/nvidia-docker.list | tee /etc/apt/sources.list.d/nvidia-docker.list
|
||||
|
||||
sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit nvidia-docker2
|
||||
sudo systemctl restart docker
|
||||
```
|
||||
|
||||
使用以下命令获取并运行最新的稳定镜像：
|
||||
```
|
||||
docker pull mindspore/mindspore-gpu:0.6.0-beta
|
||||
docker run -it --runtime=nvidia --privileged=true mindspore/mindspore-gpu:0.6.0-beta /bin/bash
|
||||
```
|
||||
|
||||
要测试Docker是否正常工作，请运行下面的Python代码并检查输出：
|
||||
```python
|
||||

|
||||
import mindspore.context as context
|
||||
from mindspore import Tensor
|

|
||||
|
||||
context.set_context(device_target="GPU")
|
||||
|
||||
x = Tensor(np.ones([1,3,3,4]).astype(np.float32))
|
||||
y = Tensor(np.ones([1,3,3,4]).astype(np.float32))
|
||||
print(F.tensor_add(x, y))
|
||||
