DLFlow - A Deep Learning WorkFlow

DLFlow概述

DLFlow是一套深度学习pipeline,它结合了Spark的大规模特征处理能力和Tensorflow模型构建能力。利用DLFlow可以快速处理原始特征、训练模型并进行大规模分布式预测,十分适合离线环境下的生产任务。利用DLFlow,用户只需专注于模型开发,而无需关心原始特征处理、pipeline构建、生产部署等工作。

功能支持

配置驱动: DLFlow通过配置驱动,修改配置可以快速更换特征、模型超参数、任务流程等等,极大提高工作效率。

模块化结构: 任务和模型以插件形式存在,便于使用和开发,用户可以可以轻地将自定义任务和模型注册到框架内使用。

任务自组织: 通过内置的Workflow框架,根据任务的产出标记自动解决任务依赖,轻松构建深度学习pipeline。

最佳实践: 融入滴滴用户画像团队深度学习离线任务的最佳实践,有效应对离线生产中的多种问题。将Tensorflow和Spark进行合理结合,更适合离线深度学习任务。

快速开始

环境准备

首先请确保环境中已经安装和配置Hadoop和Spark,并设置好了基本的环境变量。

  • Tensorflow访问HDFS

为了能够使用让Tensorflow访问HDFS,需要确保如下环境变量生效:

# 确保libjvm.so被添加到LD_LIBRARY_PATH
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${JAVA_HOME}/jre/lib/amd64/server

# 确保hadoop jars被添加到CLASSPATH
export CLASSPATH=${CLASSPATH}:$(hadoop classpath --glob)

关于Tensorflow访问HDFS更多内容请参见 TensorFlow on Hadoop

  • Spark读写TFReocrds
# Clone tensorflow/ecosystem项目
git clone https://github.com/tensorflow/ecosystem.git

cd ecosystem/spark/spark-tensorflow-connector/

# 构建spark-tensorflow-connector
mvn versions:set -DnewVersion=1.14.0
mvn clean install

项目构建后生成 target/spark-tensorflow-connector_2.11-1.14.0.jar,后续需要确保该jar被添加到 spark.jars 中。 关于Spark读写TFRecoreds更多内容请参见 spark-tensorflow-connector

安装

通过pip安装:

pip install dlflow

通过源代码安装:

git clone  https://github.com/didi/dlflow.git
cd dlflow
python setup.py install

使用

  • 配置文件

运行配置可参考 conf 目录中的配置。 关于配置详情请参考 配置说明

  • 以模块运行
python -m dlflow.main --config <CONFIGURATION FILE>.conf
  • 以脚本运行

确保python环境的 bin 目录已经被添加到环境变量 PATH

export PATH=$PATH:/usr/local/python/bin

之后通过如下命令运行

dlflow --config .conf
