      Add Combined NMS (#6138) · 3980d2a1
      Pooya Davoodi authored
      * Updating python API to use CombinedNonMaxSuppresion TF operator
      
      1. Adds a unit test to test post_processing python API
      2. Currently sets clip_window to None as the kernel uses the default
         clip_window of [0,0,1,1]
      3. Added use_static_shapes to the API. In old API if
         use_static_shapes is true, then it pads/clips outputs to max_total_size, if
      specified. If not specified, it pads to num_classes*max_size_per_class.
       If use_static_shapes is false, it always pads/clips to max_total_size.
      
      Update unit test to account for clipped bouding boxes
      
      Changed the name to CombinedNonMaxSuppression based on feedback from Google
      
      Added additional parameters to combinedNMS python function. They are currently
      unused and required for networks like FasterRCNN and MaskRCNN
      
      * Delete selected_indices from API
      
      Because it was removed from CombinedNMS recently in the PR.
      
      * Improve doc of function combined_non_max_suppression
      
      * Enable CombinedNonMaxSuppression for first_stage_nms
      
      * fix bug
      
      * Ensure agnostic_nms is not used with combined_nms
      
      Remove redundant arguments from combined_nms
      
      * Fix pylint
      
      * Add checks for unsupported args
      
      * Fix pylint
      
      * Move combined_non_max_suppression to batch_multiclass_non_max_suppression
      
      Also rename combined_nms to use_combined_nms
      
      * Delete combined_nms for first_stage_nms because it does not work
      
      * Revert "Delete combined_nms for first_stage_nms because it does not work"
      
      This reverts commit 2a3cc5145f17cee630a67ddedd20e90c2920fa9f.
      
      * Use nmsed_additional_fields.get to avoid error
      
      * Merge combined_non_max_suppression with main nms function
      
      * Rename combined_nms for first stage nms
      
      * Improve  docs
      
      * Use assertListEqual for numpy arrays
      
      * Fix pylint errors
      
      * End comments with period

      249878079  by Zhichao Lu:
      
          This CL slightly refactors some Object Detection helper functions for data creation, evaluation, and groundtruth providing.
      
          This will allow the eager+function custom loops to share code with the existing estimator training loops.
      
          Concretely we make the following changes:
          1. In input creation we separate dataset-creation into top-level helpers, and allow it to optionally accept a pre-constructed model directly instead of always creating a model from the config just for feature preprocessing.
      
          2. In coco evaluation we split the update_op creation into its own function, which the custom loops will call directly.
      
          3. In model_lib we move groundtruth providing/ datastructure munging into a helper function
      
          4. For now we put an escape hatch in `_summarize_target_assignment` when executing in tf v2.0 behavior because the summary apis used only work w/ tf 1.x
      
      --
      249673507  by rathodv:
      
          Use explicit casts instead of tf.to_float and tf.to_int32 to avoid warnings.
      
      --
      249656006  by Zhichao Lu:
      
          Add named "raw_keypoint_locations" node that corresponds with the "raw_box_locations" node.
      
      --
      249651674  by rathodv:
      
          Keep proposal boxes in float format. MatMulCropAndResize can handle the type even when feature themselves are bfloat16s.
      
      --
      249568633  by rathodv:
      
          Support q > 1 in class agnostic NMS.
          Break post_processing_test.py into 3 separate files to avoid linter errors.
      
      --
      249535530  by rathodv:
      
          Update some deprecated arguments to tf ops.
      
      --
      249368223  by rathodv:
      
          Modify MatMulCropAndResize to use MultiLevelRoIAlign method and move the tests to spatial_transform_ops.py module.
      
          This cl establishes that CropAndResize and RoIAlign are equivalent and only differ in the sampling point grid within the boxes. CropAndResize uses a uniform size x size point grid such that the corner points exactly overlap box corners, while RoiAlign divides boxes into size x size cells and uses their centers as sampling points. In this cl, we switch MatMulCropAndResize to use the MultiLevelRoIAlign implementation with `align_corner` option as MultiLevelRoIAlign implementation is more memory efficient on TPU when compared to the original MatMulCropAndResize.

          This change contains the auxiliary changes required for TF 2.0 style training with eager+functions+dist strat loops, but not the loops themselves.
      
          It includes:
          - Updates to shape usage to support both tensorshape v1 and tensorshape v2
          - A fix to FreezableBatchNorm to not override the `training` arg in call when `None` was passed to the constructor (Not an issue in the estimator loops but it was in the custom loops)
          - Puts some constants in init_scope so they work in eager + functions
          - Makes learning rate schedules return a callable in eager mode (required so they update when the global_step changes)
          - Makes DetectionModel a tf.module so it tracks variables (e.g. ones nested in layers)
          - Removes some references to `op.name` for some losses and replaces it w/ explicit names
          - A small part of the change to allow the coco evaluation metrics to work in eager mode

          [XLA] Rework debug flags for dumping HLO.
      
          The following flags (usually passed via the XLA_FLAGS envvar) are removed:
      
            xla_dump_computations_to
            xla_dump_executions_to
            xla_dump_ir_to
            xla_dump_optimized_hlo_proto_to
            xla_dump_per_pass_hlo_proto_to
            xla_dump_unoptimized_hlo_proto_to
            xla_generate_hlo_graph
            xla_generate_hlo_text_to
            xla_hlo_dump_as_html
            xla_hlo_graph_path
            xla_log_hlo_text
      
          The following new flags are added:
      
            xla_dump_to
            xla_dump_hlo_module_re
            xla_dump_hlo_pass_re
            xla_dump_hlo_as_text
            xla_dump_hlo_as_proto
            xla_dump_hlo_as_dot
            xla_dump_hlo_as_url
            xla_dump_hlo_as_html
            xla_dump_ir
            xla_dump_hlo_snapshots
      
          The default is not to dump anything at all, but as soon as some dumping flag is
          specified, we enable the following defaults (most of which can be overridden).
      
           * dump to stdout (overridden by --xla_dump_to)
           * dump HLO modules at the very beginning and end of the optimization pipeline
           * don't dump between any HLO passes (overridden by --xla_dump_hlo_pass_re)
           * dump all HLO modules (overridden by --xla_dump_hlo_module_re)
           * dump in textual format (overridden by
             --xla_dump_hlo_as_{text,proto,dot,url,html}).
      
          For example, to dump optimized and unoptimized HLO text and protos to /tmp/foo,
          pass
      
            --xla_dump_to=/tmp/foo --xla_dump_hlo_as_text --xla_dump_hlo_as_proto
      
          For details on these flags' meanings, see xla.proto.
      
          The intent of this change is to make dumping both simpler to use and more
          powerful.
      
          For example:
      
           * Previously there was no way to dump the HLO module during the pass pipeline
             in HLO text format; the only option was --dump_per_pass_hlo_proto_to, which
             dumped in proto format.
      
             Now this is --xla_dump_pass_re=.* --xla_dump_hlo_as_text.  (In fact, the
             second flag is not necessary in this case, as dumping as text is the
             default.)
      
           * Previously there was no way to dump HLO as a graph before and after
             compilation; the only option was --xla_generate_hlo_graph, which would dump
             before/after every pass.
      
             Now this is --xla_dump_hlo_as_{dot,url,html} (depending on what format you
             want the graph in).
      
           * Previously, there was no coordination between the filenames written by the
             various flags, so info about one module might be dumped with various
             filename prefixes.  Now the filenames are consistent and all dumps from a
             particular module are next to each other.
      
          If you only specify some of these flags, we try to figure out what you wanted.
          For example:
      
           * --xla_dump_to implies --xla_dump_hlo_as_text unless you specify some
             other --xla_dump_as_* flag.
      
           * --xla_dump_hlo_as_text or --xla_dump_ir implies dumping to stdout unless you
             specify a different --xla_dump_to directory.  You can explicitly dump to
             stdout with --xla_dump_to=-.
      
          As part of this change, I simplified the debugging code in the HLO passes for
          dumping HLO modules.  Previously, many tests explicitly VLOG'ed the HLO module
          before, after, and sometimes during the pass.  I removed these VLOGs.  If you
          want dumps before/during/after an HLO pass, use --xla_dump_pass_re=<pass_name>.

          [tf.data] Switching tf.data functions to use `defun`, providing an escape hatch to continue using the legacy `Defun`.
      
          There are subtle differences between the implementation of `defun` and `Defun` (such as resources handling or control flow) and it is possible that input pipelines that use control flow or resources in their functions might be affected by this change. To migrate majority of existing pipelines to the recommended way of creating functions in TF 2.0 world, while allowing (a small number of) existing pipelines to continue relying on the deprecated behavior, this CL provides an escape hatch.
      
          If your input pipeline is affected by this CL, it should apply the escape hatch by replacing `foo.map(...)` with `foo.map_with_legacy_function(...)`.

          Make calibration a post-processing step.
      
          Specifically:
          - Move the calibration config from pipeline.proto --> post_processing.proto
          - Edit post_processing_builder.py to return a calibration function. If no calibration config is provided, it None.
          - Edit SSD and FasterRCNN meta architectures to optionally call the calibration function on detection scores after score conversion and before NMS.

      232704481  by Zhichao Lu:
      
          Edit calibration builder to build a function that will be used within a detection model's `postprocess` method, after score conversion and before non-maxima suppression.
      
          Specific Edits:
          - The returned function now accepts class_predictions_with_background as its argument instead of detection_scores and detection_classes.
          - Class-specific calibration was temporarily removed, as it requires more significant refactoring. Will be added later.

      232399572  by Zhichao Lu:
      
          Edit calibration builder and proto to support class-agnostic calibration.
      
          Specifically:
          - Edit calibration protos to include path to relevant label map if required for class-specific calibration. Previously, label maps were inferred from other parts of the pipeline proto; this allows all information required by the builder stay within the calibration proto and remove extraneous information from being passed with class-agnostic calibration.
          - Add class-agnostic protos to the calibration config.
      
          Note that the proto supports sigmoid and linear interpolation parameters, but the builder currently only supports linear interpolation.
      
      --
      231613048  by Zhichao Lu:
      
          Add calibration builder for applying calibration transformations from output of object detection models.
      
          Specifically:
          - Add calibration proto to support sigmoid and isotonic regression (stepwise function) calibration.
          - Add a builder to support calibration from isotonic regression outputs.
      
      --
      231519786  by lzc:
      
          model_builder test refactor.
          - removed proto text boilerplate in each test case and let them call a create_default_proto function instead.
          - consolidated all separate ssd model creation tests into one.
          - consolidated all separate faster rcnn model creation tests into one.
          - used parameterized test for testing mask rcnn models and use_matmul_crop_and_resize
          - added all failures test.

      220193337  by Zhichao Lu:
      
          This CL fixes a bug where the Keras convolutional box predictor was applying heads in the non-deterministic dict order. The consequence of this bug was that variables were created in non-deterministic orders. This in turn led different workers in a multi-gpu training setup to have slightly different graphs which had variables assigned to mismatched parameter servers. As a result, roughly half of all workers were unable to initialize and did no work, and training time was slowed down approximately 2x.

          Migrate TensorFlow Lite out of tensorflow/contrib
      
          This change moves //tensorflow/contrib/lite to //tensorflow/lite in preparation
          for TensorFlow 2.0's deprecation of contrib/. If you refer to TF Lite build
          targets or headers, you will need to update them manually. If you use TF Lite
          from the TensorFlow python package, "tf.contrib.lite" now points to "tf.lite".
          Please update your imports as soon as possible.
      
          For more details, see https://groups.google.com/a/tensorflow.org/forum/#!topic/tflite/iIIXOTOFvwQ
      
          @angersson and @aselle are conducting this migration. Please contact them if
          you have any further questions.
