The instructions provided below specify the steps to build TensorFlow Transform version 1.14.0 on Linux on IBM Z for the following distributions:

• Ubuntu (20.04, 22.04)

• When following the steps below please use a standard permission user unless otherwise specified.
• A directory /<source_root>/ will be referred to in these instructions, this is a temporary writable directory anywhere you'd like to place it.

If you want to build TensorFlow Transform using manual steps, go to STEP 1.2.

Use the following commands to build TensorFlow Transform using the build script. Please make sure you have wget installed.

wget -q https://raw.githubusercontent.com/linux-on-ibm-z/scripts/master/TensorflowTransform/1.14.0/build_tensorflow_transform.sh

# Build TensorFlow Transform
bash build_tensorflow_transform.sh    [Provide -t option for executing build with tests, -p option for choosing the Python version from {3.8, 3.9, 3.10}, if not specified, the script will use the distro provided Python version (i.e., Python 3.8 on Ubuntu 20.04 and Python 3.10 on Ubuntu 22.04).]

If the build completes successfully, go to STEP 2. In case of error, check logs for more details or go to STEP 1.2 to follow manual build steps.

export SOURCE_ROOT=/<source_root>/

• Ubuntu 20.04

  sudo apt-get update
  sudo apt-get install -y build-essential cargo curl git libopenblas-dev

• Ubuntu 22.04

  sudo apt-get update
  sudo apt-get install -y build-essential cargo curl git cmake libopenblas-dev

• The instructions for building TensorFlow 2.13.0 can be found here.

• For Ubuntu 20.04, use the following commands to build TensorFlow 2.13.0 with the distribution provided python version (3.8 at the time of writing):

  cd $SOURCE_ROOT
  wget -O build_tensorflow.sh https://raw.githubusercontent.com/linux-on-ibm-z/scripts/master/Tensorflow/2.13.0/build_tensorflow.sh
  bash build_tensorflow.sh -y

• For Ubuntu 22.04, use the following commands to build TensorFlow 2.13.0 with python 3.9 which is the highest python version supported by TensorFlow Transform:

  cd $SOURCE_ROOT
  wget -O build_tensorflow.sh https://raw.githubusercontent.com/linux-on-ibm-z/scripts/master/Tensorflow/2.13.0/build_tensorflow.sh
  bash build_tensorflow.sh -y -p 3.9

• Build CMake 3.21.2 (only on Ubuntu 20.04)

  cd $SOURCE_ROOT
  wget https://github.com/Kitware/CMake/releases/download/v3.21.2/cmake-3.21.2.tar.gz
  tar -xzf cmake-3.21.2.tar.gz
  cd cmake-3.21.2
  ./bootstrap --prefix=/usr
  make
  sudo make install

• Download source code

  cd $SOURCE_ROOT
  git clone https://github.com/apache/arrow.git
  cd arrow
  git checkout apache-arrow-10.0.1

• Build and install Arrow C++ library

  cd $SOURCE_ROOT/arrow/cpp
  mkdir release
  cd release
  cmake -DCMAKE_INSTALL_PREFIX=/usr/local \
     -DARROW_PARQUET=ON \
     -DARROW_PYTHON=ON \
     -DCMAKE_BUILD_TYPE=Release \
     ..
  make -j4
  sudo make install
  export LD_LIBRARY_PATH=/usr/local/lib${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

• Build and install pyarrow library

  cd $SOURCE_ROOT/arrow/python
  curl -o pyarrow.diff https://raw.githubusercontent.com/linux-on-ibm-z/scripts/master/TensorflowTransform/1.14.0/patch/pyarrow.diff
  git apply pyarrow.diff
  export PYARROW_WITH_PARQUET=1
  export PYARROW_PARALLEL=4
  sudo pip3 install -r requirements-build.txt
  python setup.py build_ext bdist_wheel
  sudo pip3 install dist/*.whl

• Build and install Apache Beam

  cd $SOURCE_ROOT
  sudo GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=True pip3 install numpy==1.22.4 scipy==1.7.3 'apache-beam[gcp]'==2.47.0

• Download source code

  cd $SOURCE_ROOT
  git clone https://github.com/tensorflow/tfx-bsl.git
  cd tfx-bsl
  git checkout v1.14.0

• Build and install tfx-bsl

  cd $SOURCE_ROOT
  curl -o tfx-bsl.diff https://raw.githubusercontent.com/linux-on-ibm-z/scripts/master/TensorflowTransform/1.14.0/patch/tfx-bsl.diff
  cd tfx-bsl
  patch -p1 < ../tfx-bsl.diff
  
  sudo touch /usr/local/include/immintrin.h
  
  python3 setup.py bdist_wheel
  sudo pip3 install dist/*.whl

cd $SOURCE_ROOT
sudo pip3 install tensorflow-transform==1.14.0

It is also possible to build and install TensorFlow Transform manually. This step is required if you intend to run the test cases as in Step 3.

• Download source code

  cd $SOURCE_ROOT
  git clone https://github.com/tensorflow/transform.git
  cd transform
  git checkout v1.14.0

• Build and install

  sudo python3 setup.py install

Note: If any other particular version of a python package is required during installation, please run sudo pip3 install '<package-name>==<version>' to install it:

• Run TensorFlow Transform from command Line

  $ cd $SOURCE_ROOT
  $ python3
   >>> import tensorflow as tf
   >>> import tensorflow_transform as tft
   >>> tft.version.__version__
   '1.14.0'
   >>>

• Follow instructions in this tutorial to use TensorFlow Transform to preprocess data.

• Run the complete testsuite

  cd $SOURCE_ROOT/transform
  python3 -m unittest discover -v -p '*_test.py'

• Run a single test case (for example BeamImplTest.testHandleBatchError)

  cd $SOURCE_ROOT/transform
  python3 -m unittest -v tensorflow_transform/beam/impl_test.py -k BeamImplTest.testHandleBatchError

Note: Test case BeamImplTest.testNumericAnalyzersWithCompositeInputssparse_elementwise_tf.float64 fails intermittently on both s390x and Intel but will pass after an individual rerun.
