**NNI (Neural Network Intelligence)** is an efficient and automatic toolkit to help users design and search neural network architecture, tune machine learning model's parameters or complex system's parameters. The tool manages automated machine learning (AutoML) experiments, dispatches and runs experiments' trial jobs generated by tuning algorithms to search the best neural architecture and/or hyper-parameters in different environments like local machine, remote servers and cloud.
**NNI (Neural Network Intelligence)** is a lightweight but powerful toolkit to help users **automate** <a href="docs/en_US/FeatureEngineering/Overview.md">Feature Engineering</a>, <a href="docs/en_US/NAS/Overview.md">Neural Architecture Search</a>, <a href="docs/en_US/Tuner/BuiltinTuner.md">Hyperparameter Tuning</a> and <a href="docs/en_US/Compressor/Overview.md">Model Compression</a>.
The tool manages automated machine learning (AutoML) experiments, **dispatches and runs** experiments' trial jobs generated by tuning algorithms to search the best neural architecture and/or hyper-parameters in **different training environments** like <a href="docs/en_US/TrainingService/LocalMode.md">Local Machine</a>, <a href="docs/en_US/TrainingService/RemoteMachineMode.md">Remote Servers</a>, <a href="docs/en_US/TrainingService/PaiMode.md">OpenPAI</a>, <a href="docs/en_US/TrainingService/KubeflowMode.md">Kubeflow</a>, <a href="docs/en_US/TrainingService/FrameworkControllerMode.md">FrameworkController on K8S (AKS etc.)</a> and other cloud options.
## **Who should consider using NNI**
* Those who want to **try different AutoML algorithms** in their training code/model.
* Those who want to run AutoML trial jobs **in different environments** to speed up search.
* Researchers and data scientists who want to easily **implement and experiement new AutoML algorithms**, may it be: hyperparameter tuning algorithm, neural architect search algorithm or model compression algorithm.
* ML Platform owners who want to **support AutoML in their platform**.
### **NNI v1.2 has been released! &nbsp;<a href="#nni-released-reminder"><img width="48" src="docs/img/release_icon.png"></a>**
## **NNI capabilities in a glance**
NNI provides CommandLine Tool as well as an user friendly WebUI to manage training experiements. With the extensible API, you can customize your own AutoML algorithms and training services. To make it easy for new users, NNI also provides a set of build-in stat-of-the-art AutoML algorithms and out of box support for popular training platforms.
Within the following table, we summarized the current NNI capabilities, we are gradually adding new capabilities and we'd love to have your contribution.

### multiPhase
__logCollection__ set the way to collect log in remote, pai, kubeflow, frameworkcontroller platform. There are two ways to collect log, one way is from `http`, trial keeper will post log content back from http request in this way, but this way may slow down the speed to process logs in trialKeeper. The other way is `none`, trial keeper will not post log content back, and only post job metrics. If your log content is too big, you could consider setting this param be `none`.
Optional. Bool. Default: false.

Unable to open the WebUI may have the following reasons:
* http://127.0.0.1, http://172.17.0.1 and http://10.0.0.15 are referred to localhost, if you start your experiment on the server or remote machine. You can replace the IP to your server IP to view the WebUI, like http://[your_server_ip]:8080

* If you still can't see the WebUI after you use the server IP, you can check the proxy and the firewall of your machine. Or use the browser on the machine where you start your NNI experiment.
* Another reason may be your experiment is failed and NNI may fail to get the experiment information. You can check the log of NNIManager in the following directory: ~/nni/experiment/[your_experiment_id] /log/nnimanager.log
* Another reason may be your experiment is failed and NNI may fail to get the experiment information. You can check the log of NNIManager in the following directory: `~/nni/experiment/[your_experiment_id]` `/log/nnimanager.log`
### Restful server start failed
Probably it's a problem with your network config. Here is a checklist.
* You might need to link `127.0.0.1` with `localhost`. Add a line `127.0.0.1 localhost` to `/etc/hosts`.
* It's also possible that you have set some proxy config. Check your environment for variables like `HTTP_PROXY` or `HTTPS_PROXY` and unset if they are set.

TensorFlow 代码
PyTorch 代码
```python
from nni.compression.tensorflow import LevelPruner
from nni.compression.torch import LevelPruner
config_list = [{ 'sparsity': 0.8, 'op_types': ['default'] }]
pruner = LevelPruner(tf.get_default_graph(), config_list)

```python
from nni.compression.torch import LevelPruner
from nni.compression.tensorflow import LevelPruner
config_list = [{ 'sparsity': 0.8, 'op_types': ['default'] }]
pruner = LevelPruner(model, config_list)
pruner = LevelPruner(tf.get_default_graph(), config_list)
pruner.compress()

可使用 `nni.compression` 中的其它压缩算法。 此算法分别在 `nni.compression.torch` 和 `nni.compression.tensorflow` 中实现，支持 PyTorch 和 TensorFlow。 参考 [Pruner](./Pruner.md) 和 [Quantizer](./Quantizer.md) 进一步了解支持的算法。

函数调用 `pruner.compress()` 来修改用户定义的模型（在 Tensorflow 中，通过 `tf.get_default_graph()` 来获得模型，而 PyTorch 中 model 是定义的模型类），并修改模型来插入 mask。 然后运行模型时，这些 mask 即会生效。 mask 可在运行时通过算法来调整。

# NNI 中的 DARTS
## 介绍
论文 [DARTS: Differentiable Architecture Search](https://arxiv.org/abs/1806.09055) 通过可微分的方式来解决架构搜索中的伸缩性挑战。 此方法基于架构的连续放松的表示，从而允许在架构搜索时能使用梯度下降。
为了实现，作者在小批量中交替优化网络权重和架构权重。 还进一步探讨了使用二阶优化（unroll）来替代一阶，来提高性能的可能性。
NNI 的实现基于[官方实现](https://github.com/quark0/darts)以及一个[第三方实现](https://github.com/khanrc/pt.darts)。 目前，在 CIFAR10 上从头训练的一阶和二阶优化均已实现。
## 重现结果
为了重现本文的结果，我们做了一阶和二阶优化的实验。 由于时间限制，我们仅从第二阶段重新训练了*一次**最佳架构*。 我们的结果目前与论文的结果相当。 稍后会增加更多结果
| | 论文中 | 重现 |

| 一阶 (CIFAR10) | 3.00 +/- 0.14 | 2.78 |
| 二阶（CIFAR10） | 2.76 +/- 0.09 | 2.89 |

# NNI 中的 ENAS
## 介绍
论文 [Efficient Neural Architecture Search via Parameter Sharing](https://arxiv.org/abs/1802.03268) 通过在子模型之间共享参数来加速 NAS 过程。 在 ENAS 中，Contoller 学习在大的计算图中搜索最有子图的方式来发现神经网络。 Controller 通过梯度策略训练，从而选择出能在验证集上有最大期望奖励的子图。 同时对与所选子图对应的模型进行训练，以最小化规范交叉熵损失。
NNI 的实现基于 [Tensorflow 的官方实现](https://github.com/melodyguan/enas)，包括了 CIFAR10 上的 Macro/Micro 搜索空间。 NNI 中从头训练的代码还未完成，当前还没有重现结果。

## 核心功能
NNI 提供了并行运行多个实例以查找最佳参数组合的能力。 此功能可用于各种领域，例如，为深度学习模型查找最佳超参数，或查找具有真实数据的数据库和其他复杂系统的最佳配置。
NNI 还希望提供用于机器学习和深度学习的算法工具包，尤其是神经体系结构搜索（NAS）算法，模型压缩算法和特征工程算法。
### 超参调优
这是 NNI 最核心、基本的功能，其中提供了许多流行的[自动调优算法](Tuner/BuiltinTuner.md) (即 Tuner) 以及 [提前终止算法](Assessor/BuiltinAssessor.md) (即 Assessor)。 可查看[快速入门](Tutorial/QuickStart.md)来调优模型或系统。 基本上通过以上三步，就能开始NNI Experiment。
### 通用 NAS 框架
此 NAS 框架可供用户轻松指定候选的神经体系结构，例如，可以为单个层指定多个候选操作（例如，可分离的 conv、扩张 conv），并指定可能的跳过连接。 NNI 将自动找到最佳候选。 另一方面，NAS 框架为其他类型的用户（如，NAS 算法研究人员）提供了简单的接口，以实现新的 NAS 算法。 详情及用法参考[这里](NAS/Overview.md)。
NNI 通过 Trial SDK 支持多种 one-shot NAS 算法，如：ENAS、DARTS。 使用这些算法时，不需启动 NNI Experiment。 在 Trial 代码中加入算法，直接运行即可。 如果要调整算法中的超参数，或运行多个实例，可以使用 Tuner 并启动 NNI Experiment。
除了 one-shot NAS 外，NAS 还能以 NNI 模式运行，其中每个候选的网络结构都作为独立 Trial 任务运行。 在此模式下，与超参调优类似，必须启动 NNI Experiment 并为 NAS 选择 Tuner。
### 模型压缩
NNI 上的模型压缩包括剪枝和量化算法。 这些算法通过 NNI Trial SDK 提供。 可以直接在 Trial 代码中使用，并在不启动 NNI Experiment 的情况下运行 Trial 代码。 详情及用法参考[这里](Compressor/Overview.md)。
模型压缩中有不同的超参。 一种类型是在输入配置中的超参，例如，压缩算法的稀疏性、量化的位宽。 另一种类型是压缩算法的超参。 NNI 的超参调优可以自动找到最佳的压缩模型。 参考[简单示例](Compressor/AutoCompression.md)。
### 自动特征工程
自动特征工程，为下游任务找到最有效的特征。 详情及用法参考[这里](FeatureEngineering/Overview.md)。 通过 NNI Trial SDK 支持，不必创建 NNI Experiment。 只需在 Trial 代码中加入内置的自动特征工程算法，然后直接运行 Trial 代码。
自动特征工程算法通常有一些超参。 如果要自动调整这些超参，可以利用 NNI 的超参数调优，即选择调优算法（即 Tuner）并启动 NNI Experiment。
