Tensorflow Cookbook

Author: Jim Dowling

OS support: Ubuntu 16+, Centos 7+

Requirements for Vagrant installation: chefdk

##Vagrant Usage

Install chefdk (https://downloads.chef.io/chef-dk)

./run-vagrant.sh

Karamel Usages

  1. Create a project "tf"
  2. upload tf.csv to tf/Resources in hdfs

source $HADOOP_HOME/libexec/hadoop-config.sh export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JAVA_HOME/jre/lib/amd64/server CLASSPATH=$($HADOOP_HDFS_HOME/bin/hdfs classpath --glob) python test-read.py

To HDFS with TensorFlow, change the file paths you use to read and write data to an HDFS path. For example:

filename_queue = tf.train.string_input_producer([ "hdfs://namenode:8020/path/to/file1.csv", "hdfs://namonode:8020/path/to/file2.csv", ]) If you want to use the namenode specified in your HDFS configuration files, then change the file prefix to hdfs://default/.

When launching your TensorFlow program, the following environment variables must be set:

JAVA_HOME: The location of your Java installation. HADOOP_HDFS_HOME: The location of your HDFS installation. You can also set this environment variable by running: source $HADOOP_HOME/libexec/hadoop-config.sh LD_LIBRARY_PATH: To include the path to libjvm.so. On Linux: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JAVA_HOME/jre/lib/amd64/server CLASSPATH: The Hadoop jars must be added prior to running your TensorFlow program. The CLASSPATH set by $HADOOP_HOME/libexec/hadoop-config.sh is insufficient. Globs must be expanded as described in the libhdfs documentation: CLASSPATH=$($HADOOP_HDFS_HOME/bin/hdfs classpath --glob) python your_script.py
