nni 环境搭建

1. 创建虚拟环境

conda create -n nni python=3.7
conda activate nni

2. 安装nni

pip install nni==1.9 tensorflow==1.15.4  # 需要手动安装tf 1.x
git clone -b v1.9 https://gitee.com/oaksharks/nni.git  # 需要源码运行样例

3. 遇到的问题

启动任务时候遇到报错：

internal/modules/cjs/loader.js:883
  throw err;
  ^

  ]
}

解决办法：

$ cd /home/oaksharks/miniconda3/envs/nni/nni/node_modules
yarn install

4. 启动实验

nnictl create --port 8480 --config nni/examples/trials/mnist-tfv1/config.yml
# nnictl experiment show # 查看执行中的任务
# nnictl stop # 关闭运行中的任务
