- Post export metrics will now also search for prediction keys prefixed by metric_tag if it is specified.
- Added support for precision/recall @ k using canned estimators provided label vocab not used.

- Removed internal usages of encoding.NODE_SUFFIX indirection within dicts in the eval_saved_model module (encoding.NODE_SUFFIX is still used in FeaturesPredictionLabels)
- Predictions are now returned as tensors (vs dicts) when "predictions" is the only output (this is consistent with how features and labels work).
- Depends on
apache-beam[gcp]>=2.11,<3. - Depends on
protobuf>=3.7,<4. - Depends on
scipy==1.1.0. - Add support for multiple plots in a single evaluation.

- Fixed bugs where TFMA was incorrectly modifying elements in DoFns, which violates the Beam API.
- Fixed correctness issue stemming from TFMA incorrectly relying on evaluation ordering that TF doesn't guarantee.
- We now store feature and label Tensor information in SignatureDef inputs instead of Collections in anticipation of Collections being deprecated in TF 2.0.
- Add support for fractional labels in AUC, AUPRC and confusion matrix at
thresholds. Previously the labels were being passed directly to TensorFlow,
which would cast them to
bool, which meant that all non-zero labels were treated as positive examples. Now we treat a fractional labellin[0, 1]as two examples, a positive example with weightland a negative example with weight1 - l. - Depends on
numpy>=1.14.5,<2. - Depends on
scipy==0.19.1. - Depends on
protobuf==3.7.0rc2. - Chicago Taxi example is moved to tfx repo (https://github.com/tensorflow/tfx/tree/master/tfx/examples/chicago_taxi)

- We now support unsupervised models which have
model_fns that do not take alabelsargument. - Improved performance by using
make_callableinstead of repeatedsession.runcalls. - Improved performance by better choice of default "combine" batch size.
- We now support passing in custom extractors in the model_eval_lib API.
- Added support for models which have multiple examples per raw input (e.g.
input is a compressed example which expands to multiple examples when parsed
by the model). For such models, you must specify an
example_refparameter to yourEvalInputReceiver. This 1-D integer Tensor should be batch aligned with features, predictions and labels and each element in it is an index in the raw input tensor to identify which input each feature / prediction / label came from. Seeeval_saved_model/example_trainers/fake_multi_examples_per_input_estimator.pyfor an example. - Added support for metrics with string
value_ops. - Added support for metrics whose
value_ops return multidimensional arrays. - We now support including your serving graph in the EvalSavedModel. You can
do this by passing a
serving_input_receiver_fntoexport_eval_savedmodelor any of the TFMA Exporters. - We now support customizing prediction and label keys for post_export_metrics.
- Depends on
apache-beam[gcp]>=2.8,<3. - Depends on

- Potentially improved performance by fanning out large slices.
- Add support for assets_extra in
tfma.exporter.FinalExporter. - Add a light-weight library that includes only the export-related modules for
TFMA for use in your Trainer. See docstring in
tensorflow_model_analysis/export_only/__init__.pyfor usage. - Update
EvalInputReceiverso the TFMA collections written to the graph only contain the results of the last call if multiple calls toEvalInputReceiverare made. - We now finalize the graph after it's loaded and post-export metrics are added, potentially improving performance.
- Fix a bug in post-export PrecisionRecallAtK where labels with only 1 dimension were not correctly handled.
- Fix an issue where we were not correctly wrapping SparseTensors for
featuresandlabelsintf.identity, which could cause TFMA to encounter TensorFlow issue #17568 if there were control dependencies on thesefeaturesorlabels. - We now correctly preserve
dtypeswhen splitting and concatenating SparseTensors internally. The failure to do so previously could result in unexpectedly large memory usage if string values were involved due to the inefficient pickling of NumPy string arrays with a large number of elements.
- Requires pre-installed TensorFlow >=1.11,<2.
- We now require that
EvalInputReceiver,export_eval_savedmodel,make_export_strategy,make_final_exporter,FinalExporterandLatestExporterbe called with keyword arguments only. - Removed
check_metric_compatibilityfromEvalSavedModel. - We now enforce that the
receiver_tensorsdictionary forEvalInputReceivercontains exactly one key namedexamples. - Post-export metrics have now been moved up one level to
tfma.post_export_metrics. They should now be accessed viatfma.post_export_metrics.aucinstead oftfma.post_export_metrics.post_export_metrics.aucas they were before. - Separated extraction from evaluation.
EvaluteAndWriteResultsis now calledExtractEvaluateAndWriteResults. - Added
EvalSharedModeltype to encapsulatemodel_pathandadd_metrics_callbacksalong with a handle to a shared model instance.
- Improved performance especially when slicing across many features and/or feature values.
- Depends on
tensorflow-transform>=0.9,<1. - Requires pre-installed TensorFlow >=1.9,<2.
- Depends on
apache-beam[gcp]>=2.6,<3. - Updated ExampleCount to use the batch dimension as the example count. It also now tries a few fallbacks if none of the standard keys are found in the predictions dictionary: the first key in sorted order in the predictions dictionary, or failing that, the first key in sorted order in the labels dictionary, or failing that, it defaults to zero.
- Fix bug where we were mutating an element in a DoFn - this is prohibited in the Beam model and can cause subtle bugs.
- Fix bug where we were creating a separate Shared handle for each stage in Evaluate, resulting in no sharing of the model across stages.
- Requires pre-installed TensorFlow >=1.10,<2.
- Add a TFMA unit test library for unit testing your the exported model and associated metrics computations.
- Add
tfma.export.make_export_strategywhich is analogous totf.contrib.learn.make_export_strategy. - Add
tfma.exporter.FinalExporterandtfma.exporter.LatestExporterwhich are analogous totf.estimator.FinalExporterandtf.estimator.LastExporter. - Add
tfma.export.build_parsing_eval_input_receiver_fnwhich is analogous totf.estimator.export.build_parsing_serving_input_receiver_fn. - Add integration testing for DNN-based estimators.
- Add new post export metrics:
- AUC (
tfma.post_export_metrics.post_export_metrics.auc) - Precision/Recall at K
(
tfma.post_export_metrics.post_export_metrics.precision_recall_at_k) - Confusion matrix at thresholds
(
tfma.post_export_metrics.post_export_metrics.confusion_matrix_at_thresholds)
- AUC (
- Peak memory usage for large DataFlow jobs should be lower with a fix in when we compact batches of metrics during the combine phase of metrics computation.
- Remove batch size override in
chicago_taxiexample. - Added dependency on
protobuf>=3.6.0<4for protocol buffers. - Updated SparseTensor code to work with SparseTensors of any dimension. Previously on SparseTensors with dimension 2 (batch_size x values) were supported in the features dictionary.
- Updated code to work with SparseTensors and dense Tensors of variable lengths across batches.
- EvalSavedModels produced by TFMA 0.6.0 will not be compatible with later
versions due to the following changes:
- EvalSavedModels are now written out with a custom "eval_saved_model" tag, as opposed to the "serving" tag before.
- EvalSavedModels now include version metadata about the TFMA version that they were exported with.
- Metrics and plot outputs now are converted into proto and serialized. Metrics and plots produced by TFMA 0.6.0 will not be compatible with later versions.
- Requires pre-installed TensorFlow >=1.9,<2.
- TFMA now uses the TensorFlow Estimator functionality for exporting models of different modes behind the scenes. There are no user-facing changes API-wise, but EvalSavedModels produced by earlier versions of TFMA will not be compatible with this version of TFMA.
- tf.contrib.learn Estimators are no longer supported by TFMA. Only tf.estimator Estimators are supported.
- Metrics and plot outputs now include version metadata about the TFMA version that they were exported with. Metrics and plots produced by earlier versions of TFMA will not be compatible with this version of TFMA.
- Initial release of TensorFlow Model Analysis.
