TensorFlow Ranking is a library for Learning-to-Rank (LTR) techniques on the TensorFlow platform

Last update: Jan 04, 2023

Overview

TensorFlow Ranking

TensorFlow Ranking is a library for Learning-to-Rank (LTR) techniques on the TensorFlow platform. It contains the following components:

Commonly used loss functions including pointwise, pairwise, and listwise losses.
Commonly used ranking metrics like Mean Reciprocal Rank (MRR) and Normalized Discounted Cumulative Gain (NDCG).
Multi-item (also known as groupwise) scoring functions.
LambdaLoss implementation for direct ranking metric optimization.
Unbiased Learning-to-Rank from biased feedback data.

We envision that this library will provide a convenient open platform for hosting and advancing state-of-the-art ranking models based on deep learning techniques, and thus facilitate both academic research and industrial applications.

Tutorial Slides

TF-Ranking was presented at premier conferences in Information Retrieval, SIGIR 2019 and ICTIR 2019! The slides are available here.

Demos

We provide a demo, with no installation required, to get started on using TF-Ranking. This demo runs on a colaboratory notebook, an interactive Python environment. Using sparse features and embeddings in TF-Ranking . This demo demonstrates how to:

Use sparse/embedding features
Process data in TFRecord format
Tensorboard integration in colab notebook, for Estimator API

Also see Running Scripts for executable scripts.

Linux Installation

Stable Builds

To install the latest version from PyPI, run the following:

# Installing with the `--upgrade` flag ensures you'll get the latest version.
pip install --user --upgrade tensorflow_ranking

To force a Python 3-specific install, replace pip with pip3 in the above commands. For additional installation help, guidance installing prerequisites, and (optionally) setting up virtual environments, see the TensorFlow installation guide.

Note: Since TensorFlow is now included as a dependency of the TensorFlow Ranking package (in setup.py). If you wish to use different versions of TensorFlow (e.g., tensorflow-gpu), you may need to uninstall the existing verison and then install your desired version:

$ pip uninstall tensorflow
$ pip install tensorflow-gpu

Installing from Source

To build TensorFlow Ranking locally, you will need to install:
- Bazel, an open source build tool.
```
$ sudo apt-get update && sudo apt-get install bazel
```
- Pip, a Python package manager.
```
$ sudo apt-get install python-pip
```
- VirtualEnv, a tool to create isolated Python environments.
```
$ pip install --user virtualenv
```

Clone the TensorFlow Ranking repository.

$ git clone https://github.com/tensorflow/ranking.git

Build TensorFlow Ranking wheel file and store them in /tmp/ranking_pip folder.

$ cd ranking  # The folder which was cloned in Step 2.
$ bazel build //tensorflow_ranking/tools/pip_package:build_pip_package
$ bazel-bin/tensorflow_ranking/tools/pip_package/build_pip_package /tmp/ranking_pip

Install the wheel package using pip. Test in virtualenv, to avoid clash with any system dependencies.

$ ~/.local/bin/virtualenv -p python3 /tmp/tfr
$ source /tmp/tfr/bin/activate
(tfr) $ pip install /tmp/ranking_pip/tensorflow_ranking*.whl

In some cases, you may want to install a specific version of tensorflow, e.g., tensorflow-gpu or tensorflow==2.0.0. To do so you can either

(tfr) $ pip uninstall tensorflow
(tfr) $ pip install tensorflow==2.0.0

(tfr) $ pip uninstall tensorflow
(tfr) $ pip install tensorflow-gpu

Run all TensorFlow Ranking tests.

(tfr) $ bazel test //tensorflow_ranking/...

Invoke TensorFlow Ranking package in python (within virtualenv).
```
(tfr) $ python -c "import tensorflow_ranking"
```

Running Scripts

For ease of experimentation, we also provide a TFRecord example and a LIBSVM example in the form of executable scripts. This is particularly useful for hyperparameter tuning, where the hyperparameters are supplied as flags to the script.

TFRecord Example

Set up the data and directory.

MODEL_DIR=/tmp/tf_record_model && \
TRAIN=tensorflow_ranking/examples/data/train_elwc.tfrecord && \
EVAL=tensorflow_ranking/examples/data/eval_elwc.tfrecord && \
VOCAB=tensorflow_ranking/examples/data/vocab.txt

Build and run.

rm -rf $MODEL_DIR && \
bazel build -c opt \
tensorflow_ranking/examples/tf_ranking_tfrecord_py_binary && \
./bazel-bin/tensorflow_ranking/examples/tf_ranking_tfrecord_py_binary \
--train_path=$TRAIN \
--eval_path=$EVAL \
--vocab_path=$VOCAB \
--model_dir=$MODEL_DIR \
--data_format=example_list_with_context

LIBSVM Example

Set up the data and directory.

OUTPUT_DIR=/tmp/libsvm && \
TRAIN=tensorflow_ranking/examples/data/train.txt && \
VALI=tensorflow_ranking/examples/data/vali.txt && \
TEST=tensorflow_ranking/examples/data/test.txt

Build and run.

rm -rf $OUTPUT_DIR && \
bazel build -c opt \
tensorflow_ranking/examples/tf_ranking_libsvm_py_binary && \
./bazel-bin/tensorflow_ranking/examples/tf_ranking_libsvm_py_binary \
--train_path=$TRAIN \
--vali_path=$VALI \
--test_path=$TEST \
--output_dir=$OUTPUT_DIR \
--num_features=136 \
--num_train_steps=100

TensorBoard

The training results such as loss and metrics can be visualized using Tensorboard.

(Optional) If you are working on remote server, set up port forwarding with this command.
```
$ ssh <remote-server> -L 8888:127.0.0.1:8888
```

Install Tensorboard and invoke it with the following commands.

(tfr) $ pip install tensorboard
(tfr) $ tensorboard --logdir $OUTPUT_DIR

Jupyter Notebook

An example jupyter notebook is available in tensorflow_ranking/examples/handling_sparse_features.ipynb.

To run this notebook, first follow the steps in installation to set up virtualenv environment with tensorflow_ranking package installed.
Install jupyter within virtualenv.
```
(tfr) $ pip install jupyter
```

Start a jupyter notebook instance on remote server.

(tfr) $ jupyter notebook tensorflow_ranking/examples/handling_sparse_features.ipynb \
        --NotebookApp.allow_origin='https://colab.research.google.com' \
        --port=8888

(Optional) If you are working on remote server, set up port forwarding with this command.
```
$ ssh <remote-server> -L 8888:127.0.0.1:8888
```
Running the notebook.
- Start jupyter notebook on your local machine at http://localhost:8888/ and browse to the ipython notebook.
- An alternative is to use colaboratory notebook via colab.research.google.com and open the notebook in the browser. Choose local runtime and link to port 8888.

Parsing ELWC example to tensors consumable by a non-EIE model
versions:

tensorflow==2.3.2

tensorflow-ranking==0.3.0

description: When the example list only contains one item, the model graph can consume the tensors parsed by tfr's parser, however, when the number of items >=2, we got errors like this from tf-serving: the following example has an item list (example list) of 2.

ERROR: Code: InvalidArgument Message: Input to reshape is a tensor with 4 values, but the requested shape has 2 [[{{node dnn/input_from_feature_columns/input_layer/feature_A_indicator_1/Reshape}}]]

Here feature_A is an indicator column of bucket size ==2, default to 0. The model is DNNLinearCombinedEstimator.

By looking at the source code, I've noticed that ELWC parser is actually EIE parser, so I'm wondering if it's because the parser constructs the tensors to a EIE fashion, so that our model can not consume the model is expecting plain batched examples?

I've tried changing the parser source code to alter the output tensors, but no luck. Any idea? Thank you!

When using ELWC - OP_REQUIRES failed at example_parsing_ops.cc:91 : Invalid argument: Could not parse example input

Hello Team,

I trained a TF ranking model (basing my training on the following example: https://github.com/tensorflow/ranking/blob/master/tensorflow_ranking/examples/tf_ranking_tfrecord.py) and saved it using estimator.export_saved_model('my_model', serving_input_receiver_fn), the model was trained successfully & saved without any warnings/errors.

I deployed the model to a local TensorFlow ModelServer and made an call to it over HTTP using cURL as described on https://www.tensorflow.org/tfx/serving/api_rest#request_format. Unfortunately I see the following error after making the request:

W external/org_tensorflow/tensorflow/core/framework/op_kernel.cc:1655] OP_REQUIRES failed at example_parsing_ops.cc:91 : Invalid argument: Could not parse example input, value: '

I understand that this is a problem that may be related to serialization where my input was not properly serialized, but saving the model by generating serving_input_receiver_fn & using it produced no errors/warnings, so I am not sure where to start looking to resolve this.

I am providing some details below, please let me know if you need more information.

Model export

Could you please give a code example of how to export a model for TensorFlow Serving? No luck with estimator.export_saved_model or tf.estimator.BestExporter. I must be doing something wrong with feature_spec.

Tensorflow_ranking with keras
Hi there,

I want to try Tensorflow_ranking with Keras. (https://github.com/tensorflow/ranking/tree/master/tensorflow_ranking/examples/keras)

As a first step I have made a copy/paste from your Github repo, but I didn't find the TEST/TRAIN/VAL dataset. I tried to use this: tensorflow_ranking/examples/data but it does not work.

My real goal to make a model that is able to rank Students in different classes based on their achievements. (Numeric and categorical features)

My questions are:

where could I find data to test code from tensorflow_ranking/examples/keras repo?

how can I use tensorflow_ranking (with Keras) when the dataset is grouped? (Class by Class)

I want to test your code with Python IDE (Spyder) so I didn't install Basel and other things.

How long does sparse-model run for ?

HI guys,

I have been running the sparse-model for the last 5 days on GPU server and I can't see anything in my models directory. Meaning it did not get even to the first check point. Anyone has had experience with this?

My features are many though (About 900K) But I still expected to be past the first checkpoint.

Any hints would help here.

Thanks.

Minimal example of prediction using TFR-BERT?

Would it be possible to have a minimal example that performs prediction (ranking) on an unseen set using TFR-BERT?

The current example ( tfrbert_example.py ) trains the model and evaluates performance on a development set, but it would be helpful to see a simple example of ranking on an unseen test set, and exporting these {query, document, rank} tuples to (for example) a plain text file for debugging.

Non-deterministic results in tf_ranking_tfrecord.py
Hello,

When I run tf_ranking_tfrecord.py, I get each time different nDCG metrics.

I have already tried the following:

tf.random.set_seed(1)

tf.compat.v1.random.set_seed(1)

shuffle=False in _input_fn()

and I have not modified group_size=1

Is it possible to make the results deterministic? And, if so, how?

Thanks.

is_label_valid in utils.py lacks support for integer targets
Hello. in function is_label_valid (line 76 of utils.py), the following code is given:

def is_label_valid(labels): """Returns a boolean `Tensor` for label validity.""" labels = tf.convert_to_tensor(value=labels) return tf.greater_equal(labels, 0.)

The result of this is an error if the target is an integer, because 0. is a float, and tf.greater_equal expects a both arguments to be of the same type. This prevents support for targets/labels that are integers.

Fix passing of keyword args to Dense layers in create_tower

Current behavior: kwargs are passed to tf.keras.Sequential.add, so they are not passed on to tf.keras.layers.Dense as intended. For example, when passing use_bias=False to create_tower with the kwarg name kernel_regularizer, it throws an exception:

Traceback (most recent call last):
  File "/Users/brussell/development/ranking/tensorflow_ranking/python/keras/layers_test.py", line 33, in test_create_tower_with_kwargs

Fix: This PR fixes the behavior by shifting the closing paren of tf.keras.layers.Dense to the correct location.

package Bert

How do I pack Bert into my textual data? I have query and document pairs, should I package only documents? I ask because of this definition:

SEQ_LENGTH = 64
context_feature_spec = {}
example_feature_spec = {
    'input_word_ids': tf.io.FixedLenFeature(
        shape=(SEQ_LENGTH,), dtype=tf.int64,
        default_value=[7] * SEQ_LENGTH),
    'input_mask': tf.io.FixedLenFeature(
        shape=(SEQ_LENGTH,), dtype=tf.int64,
        default_value=[7] * SEQ_LENGTH),
    'input_type_ids': tf.io.FixedLenFeature(
        shape=(SEQ_LENGTH,), dtype=tf.int64,
        default_value=[7] * SEQ_LENGTH)}
label_spec = (
    "relevance",
    tf.io.FixedLenFeature(shape=(1,), dtype=tf.int64, default_value=-1)
)

Onde context_feature_spec = { }

The antique dataset already has the keys - input_ids, input_mask, relevance e segment_ids. How do I do this for my texts?

No model de ranking there is 'feature_name_mapping' which it shows what I should deliver and what the model expects.

How to create tf records for a custom dataset and run TFR Ranking on it?

As the example is given in https://www.tensorflow.org/ranking/tutorials/ranking_dnn_distributed , it directly uses the TF Records and doesnt show how the data got converted into them. Even though as per format there should be just query, document and relevance in the tf record, but the code crashes everytime it runs.

Multi-MLP document representation

This is RFC on setting up multi-tower or multi-MLP document representation for TF Ranking.

If there are multiple logical groups of features, would be good to be able to create multi-MLP document representation.

For example groups such as: QU, CTR, Distances, Popularities, etc If each of those groups contains a few dozen features, it might be useful to have multi-MLP doc representation such as:

MLP(g1.[f1, f2, fn]) -> g1_h MLP(g2.[f1, f2, fn]) -> g2_h MLP(gN.[f1, f2, fn]) -> g3_h MLP(g1_h + g2_h + g3_h) -> doc_h

Has anyone attempted this with TF ranking?

v0.4.2(Jul 22, 2021)
This is the 0.4.2 release of TensorFlow Ranking. The main changes are the TFR-BERT module based on the Orbit framework in tf-models, which facilitates users to write customized training loops. The new components are:

TFR-BERT in Orbit

tfr.keras.task: This module contains the general boilerplate code to train TF-Ranking models in the Orbit framework. Particularly, there are:

RankingDataLoader, which parses an ELWC formatted data record into tensors

RankingTask, which specifies the behaviors of each training and evaluation step, as well as the training losses and evaluation metrics.

In addition, there are config data classes like RankingDataConfig and RankingTaskConfig to store configurations for above classes.

tfr.keras.premade.tfrbert_task: This module contains the TFR-BERT specification of the TF-Ranking Orbit task.

TFRBertDataLoader, which subclasses the RankingDataLoader and further specifies the feature specs of a TFR-BERT model.

TFRBertScorer and TFRBertModelBuilder, which defines a model builder that can create a TFR-BERT ranking model as a Keras model, based on tf-models’ implementation of BERT encoder.

TFRBertTask, which is a subclass of RankingTask. It defines the build_model behavior. It also defines the initialization method which would load an pretrained BERT checkpoint to initialize the encoder. It also provides the function to output the prediction results along with query ids and document ids.

In addition, there are config data classes like TFRBertDataConfig, TFRBertModelConfig and TFRBertConfig which stores configurations for above classes.

examples/keras/tfrbert_antique_train.py: This file provides an example of training a TFR-BERT model on the Antique data set. There is also an .yaml file where users can specify parameter configurations.

Dependencies: The following packages will be installed as required when installing tensorflow-ranking.

tf-models-official >= 2.5.0

tensorflow-serving-api>= 2.0.0, < 3.0.0

tensorflow==2.5.0.
