Overview

TensorFlow Data Validation

TensorFlow Data Validation (TFDV) is a library for exploring and validating machine learning data. It is designed to be highly scalable and to work well with TensorFlow and TensorFlow Extended (TFX).

TF Data Validation includes:

Scalable calculation of summary statistics of training and test data.
Integration with a viewer for data distributions and statistics, as well as faceted comparison of pairs of features (Facets)
Automated data-schema generation to describe expectations about data like required values, ranges, and vocabularies
A schema viewer to help you inspect the schema.
Anomaly detection to identify anomalies, such as missing features, out-of-range values, or wrong feature types, to name a few.
An anomalies viewer so that you can see what features have anomalies and learn more in order to correct them.

For instructions on using TFDV, see the get started guide and try out the example notebook. Some of the techniques implemented in TFDV are described in a technical paper published in SysML'19.

Caution: TFDV may be backwards incompatible before version 1.0.

Installing from PyPI

The recommended way to install TFDV is using the PyPI package:

pip install tensorflow-data-validation

Nightly Packages

TFDV also hosts nightly packages at https://pypi-nightly.tensorflow.org on Google Cloud. To install the latest nightly package, please use the following command:

pip install -i https://pypi-nightly.tensorflow.org/simple tensorflow-data-validation

This will install the nightly packages for the major dependencies of TFDV such as TFX Basic Shared Libraries (TFX-BSL) and TensorFlow Metadata (TFMD).

Build with Docker

This is the recommended way to build TFDV under Linux, and is continuously tested at Google.

1. Install Docker

Please first install docker and docker-compose by following the directions: docker; docker-compose.

2. Clone the TFDV repository

git clone https://github.com/tensorflow/data-validation
cd data-validation

Note that these instructions will install the latest master branch of TensorFlow Data Validation. If you want to install a specific branch (such as a release branch), pass -b <branchname> to the git clone command.

3. Build the pip package

Then, run the following at the project root:

sudo docker-compose build manylinux2010
sudo docker-compose run -e PYTHON_VERSION=${PYTHON_VERSION} manylinux2010

where PYTHON_VERSION is one of {35, 36, 37, 38}.

A wheel will be produced under dist/.

4. Install the pip package

pip install dist/*.whl

Build from source

1. Prerequisites

To compile and use TFDV, you need to set up some prerequisites.

Install NumPy

If NumPy is not installed on your system, install it now by following these directions.

Install Bazel

If Bazel is not installed on your system, install it now by following these directions.

2. Clone the TFDV repository

git clone https://github.com/tensorflow/data-validation
cd data-validation

3. Build the pip package

TFDV wheel is Python version dependent -- to build the pip package that works for a specific Python version, use that Python binary to run:

python setup.py bdist_wheel

You can find the generated .whl file in the dist subdirectory.

4. Install the pip package

pip install dist/*.whl

Supported platforms

TFDV is tested on the following 64-bit operating systems:

macOS 10.14.6 (Mojave) or later.
Ubuntu 16.04 or later.
Windows 7 or later.

Notable Dependencies

TensorFlow is required.

Apache Beam is required; it's the way that efficient distributed computation is supported. By default, Apache Beam runs in local mode but can also run in distributed mode using Google Cloud Dataflow and other Apache Beam runners.

Apache Arrow is also required. TFDV uses Arrow to represent data internally in order to make use of vectorized numpy functions.

Compatible versions

The following table shows the package versions that are compatible with each other. This is determined by our testing framework, but other untested combinations may also work.

Slow performance when computing stats for moderately large data set
Hi,

I like this project a lot, and thanks for releasing it! I see the potential to save a lot of time when I first receive new datasets. However, I have issues with performance.

OS: the notebook is running in a Docker container based on https://hub.docker.com/r/tensorflow/tensorflow/.

Hardware:

GPUs 16X NVIDIA® Tesla V100 GPU Memory 512GB total CPU Dual Intel Xeon Platinum 8168, 2.7 GHz, 24-cores System Memory 1.5TB

It takes me >8 hours (30900 s) to compute the statistics for a ~100 dataset, with file sizes from 0.5 MB to 300 MB, with a median of 70 MB. It's true that the Docker container introduces some overhead, but given the specs of my hardware, I think it's too much. Any tips on how to speed up computations, w/o changing hardware (i.e., no cloud)? For example, if there was an option to compute statistics in a dataframe, rather than in a protocol buffer, one could use Modin to speedup pandas computations with minimal changes to code.

PS if I use a GPU container instead, with

$ docker run --runtime=nvidia -it -p 8888:8888 tensorflow/tensorflow:latest-gpu should I see a speedup?

Statistics visualization doesn't work in Firefox

tfdv.visualize_statistics(train_stats) display nothing except a line. I print 'train_stats', it does contain the stats i wanted. so i think the steps before "tfdv.visualize_statistics(train_stats)" is all normal. My browser is firefox. where the problem is?

TFDV does not catch out-of-domain values for categorical ints

The domain of a categorical int feature is included in my schema as a string_domain (generated by using feature.int_domain.is_categorical = True).

However, when I try to run tfdv.validate_instance() on an example with an out-of-domain value for a categorical int, TFDV doesn't generate any anomalies.

Here's a Colab to reproduce.

Python 3 Support

Currently, TFDV requires Python 2.7 due to dependency on Apache Beam, which is not compatible with Python 3 yet.

But Python 3 support should be available very soon, as Apache Beam is almost Python 3 ready.

infer_schema(..., infer_feature_shape=True) should parse VarLenFeature to SparseFeature

If I understand things correctly, the desired behavior of infer_schema(..., infer_feature_shape=True) would be to infer feature shapes for FixedLenFeatures while parsing VarLenFeatures to SparseFeatures in the schema. However, my VarLenFeature currently gets parsed as a Feature with dim=0. Am I understanding this properly / am I doing something wrong?

TDFV==0.14.0 Wheel Fails Integrity Check
It appears TFDV==0.14.0 has a bad hash value and is failing the integrity check done by the resolver, pex:

Exception message: Bad hash for file 'tensorflow_data_validation/pywrap/_pywrap_tensorflow_data_validation.so'.

It has been reported (https://github.com/pypa/pip/issues/4705) that pip does not check the file hashes for integrity but other resolvers such as Pex do which leads to failures. Thus, it appears there's some mutation after the wheel is built ?

Minimal Repo:

pip install pex pex tensorflow-data-validation==0.14.0 -o tfdv.pex

thus I'm fairly sure these binaries aren't actually manylinux (or even broadly centos7) compatible.

Using tfdv to validate text based data

Hi,

After searching online whether tfdv could be used to validate data that contains text. For instance, for a dataset with sentences that have to be mapped to labels. I could not find any real useful tutorials, as the ones that I could find only go into numerical data regarding the dataset. For instance, height, weights, etc.

After looking around in the data-validation package I have found a couple of files that seem to be related to this. https://github.com/tensorflow/data-validation/blob/master/tensorflow_data_validation/statistics/generators/natural_language_stats_generator.py And https://github.com/tensorflow/data-validation/blob/master/tensorflow_data_validation/statistics/generators/natural_language_domain_inferring_stats_generator.py

Furthermore on the Tensorflow website about the StatsOptions class I found the following: https://www.tensorflow.org/tfx/data_validation/api_docs/python/tfdv/StatsOptions

Arguments | Description -- | -- enable_semantic_domain_stats | If True statistics for semantic domains are generated (e.g: image, text domains). semantic_domain_stats_sample_rate | An optional sampling rate for semantic domain statistics. If specified, semantic domain statistics is computed over a sample. vocab_paths | An optional dictionary mapping vocab names to paths. Used in the schema when specifying a NaturalLanguageDomain. The paths can either be to GZIP-compressed TF record files that have a tfrecord.gz suffix or to text files.

These arguments and files do indicate that tfdv can be used to analyze and validate data that would be used in NLP / Text classification type problems.

However, it is unclear to me how one would go about and use these features to validate text-based data? I have enabled the enable_semantic_domain_stats argument and this does give information like sequence length etc. However, how would one extend on this, and validate vocabularies for known/unknown word ratio's; etc.

Any tips or thoughts are highly appreciated! Kind Regards, Caspar

It seems like the allowlist_features and denylist_features require a tensorflow_data_validation.types.FeaturePath object, which took a bit to figure out how to construct. This doesn't seem that user friendly -- was it intended to allow a list of strings to be passed?

Code to reproduce

I can reproduce the problem in the public colab example. In the "Compute and Visualize Statistics" section of the above notebook, update the visualize_statistics call to be: tfdv.visualize_statistics(train_stats, denylist_features=['pickup_community_area']). The first feature shouldn't exist in the visualized example (if I'm calling this correctly).

Workaround code

To make this work, I have to manually construct a tensorflow_data_validation.types.FeaturePath object. Perhaps it would be better to do the filter comparison on each feature's path string?

# Show string name of feature first_feat = train_stats.datasets[0].features[0] print(first_feat.path) # Construct necessary object to make `allowlist_feature` filter work from tensorflow_data_validation import types print(types.FeaturePath.from_proto(first_feat.path)) # docs-infra: no-execute tfdv.visualize_statistics(train_stats, allowlist_features=[types.FeaturePath.from_proto(first_feat.path)])

Model Unit Testing feature

Hi, I recently checked the TensorFlow Data Validation paper (https://mlsys.org/Conferences/2019/doc/2019/167.pdf). First of all, thanks for the publishing the paper and open-sourcing this project.

But I cannot find similar features in this project with the Model Unit Testing module mentioned in section 5. Is there any plans to open-source model unit testing module or is it already open-sourced?

This version is the last version before TFDV 1.0. Once 1.0, all the TFDV public APIs (i.e. symbols in the root __init__.py) will be subject to semantic versioning. We are deprecating some public APIs in this version and they will be removed in 1.0.

Sketch-based top-k/unique stats generator now is able to detect invalid utf-8 sequences / large texts and replace them with a placeholder. It will not suffer from memory issue usually caused by image / large text features in the data. Note that this generator is not by default used yet.

Added StatsOptions.experimental_use_sketch_based_topk_uniques which enables the sketch-based top-k/unique stats generator.

Bug Fixes and Other Changes

Fixed bug in display_schema that caused domains not to be displayed.

Modified how get_schema_dataframe outputs numeric domains.

Anomalies previously (un)classified as UKNOWN_TYPE now trigger more specific anomaly types: INVALID_DOMAIN_SPECIFICATION and MULTIPLE_REASONS.

Bug Fixes and Other Changes

Newly added LifecycleStage.DISABLED is now exempt from validation (similar to LifecycleStage.DEPRECATED, etc).

Fixed a bug where TFDV blindly trusts the claim type in the provided schema. TFDV now computes the stats according to the actual type of the data, and only when the actual type matches the claim in the schema will it compute type-specific stats (e.g. categorical ints).

Added an option to control whether to add default stats generators when tfdv.GenerateStatistics().

Started using a new quantiles computation routine that does not depend on TF. This could potentially increase the performance of TFDV under certain workloads.

Extending schema_util to support sematic domains.

Moving natural_language_stats_generator to natural_language_domain_inferring_stats_generator.

Providing vocab_utils to assist in opening / loading vocabulary files.

A SchemaDiff will be reported upon J-S skew/drift.

Fixed a bug in FLOAT_TYPE_SMALL_FLOAT anomaly message.

v0.25.0(Nov 5, 2020)
Version 0.25.0

Major Features and Improvements

Add support for detecting drift and distribution skew in numeric features.

tfdv.validate_statistics now also reports the raw measurements of distribution skew/drift (if any is done), regardless whether skew/drift is detected. The report is in the drift_skew_info of the Anomalies proto (return value of validate_statistics).

From this release TFDV will also be hosting nightly packages on https://pypi-nightly.tensorflow.org. To install the nightly package use the following command:

pip install -i https://pypi-nightly.tensorflow.org/simple tensorflow-data-validation

Note: These nightly packages are unstable and breakages are likely to happen. The fix could often take a week or more depending on the complexity involved for the wheels to be available on the PyPI cloud service. You can always use the stable version of TFDV available on PyPI by running the command pip install tensorflow-data-validation .

Bug Fixes and Other Changes

Added tfdv.load_stats_binary to load stats what were written using tfdv.WriteStatisticsToText (now tfdv.WriteStatisticsToBinaryFile).

Anomalies previously (un)classified as UKNOWN_TYPE now trigger more specific anomaly types: DOMAIN_INVALID_FOR_TYPE, UNEXPECTED_DATA_TYPE, FEATURE_MISSING_NAME, FEATURE_MISSING_TYPE, INVALID_SCHEMA_SPECIFICATION

Fixed a bug that import tensorflow_data_validation would fail if IPython is not installed. IPython is an optional dependency of TFDV.
