      Internal changes for object detection. (#3656) · 001a2a61
      pkulzc authored
      * Force cast of num_classes to integer
      
      PiperOrigin-RevId: 188335318
      
      * Updating config util to allow overwriting of cosine decay learning rates.
      
      PiperOrigin-RevId: 188338852
      
      * Make box_list_ops.py and box_list_ops_test.py work with C API enabled.
      
      The C API has improved shape inference over the original Python
      code. This causes some previously-working conds to fail. Switching to smart_cond fixes this.
      
      Another effect of the improved shape inference is that one of the
      failures tested gets caught earlier, so I modified the test to reflect
      this.
      
      PiperOrigin-RevId: 188409792
      
      * Fix parallel event file writing issue.
      
      Without this change, the event files might get corrupted when multiple evaluations are run in parallel.
      
      PiperOrigin-RevId: 188502560
      
      * Deprecating the boolean flag of from_detection_checkpoint.
      
      Replace with a string field fine_tune_checkpoint_type to train_config to provide extensibility. The fine_tune_checkpoint_type can currently take value of `detection`, `classification`, or others when the restore_map is overwritten.
      
      PiperOrigin-RevId: 188518685
      
      * Automated g4 rollback of changelist 188502560
      
      PiperOrigin-RevId: 188519969
      
      * Introducing eval metrics specs for Coco Mask metrics. This allows metrics to be computed in tensorflow using the tf.learn Estimator.
      
      PiperOrigin-RevId: 188528485
      
      * Minor fix to make object_detection/metrics/coco_evaluation.py python3 compatible.
      
      PiperOrigin-RevId: 188550683
      
      * Updating eval_util to handle eval_metric_ops from multiple `DetectionEvaluator`s.
      
      PiperOrigin-RevId: 188560474
      
      * Allow tensor input for new_height and new_width for resize_image.
      
      PiperOrigin-RevId: 188561908
      
      * Fix typo in fine_tune_checkpoint_type name in trainer.
      
      PiperOrigin-RevId: 188799033
      
      * Adding mobilenet feature extractor to object detection.
      
      PiperOrigin-RevId: 188916897
      
      * Allow label maps to optionally contain an explicit background class with id zero.
      
      PiperOrigin-RevId: 188951089
      
      * Fix boundary conditions in random_pad_to_aspect_ratio to ensure that min_scale is always less than max_scale.
      
      PiperOrigin-RevId: 189026868
      
      * Fallback on from_detection_checkpoint option if fine_tune_checkpoint_type isn't set.
      
      PiperOrigin-RevId: 189052833
      
      * Add proper names for learning rate schedules so we don't see cryptic names on tensorboard.
      
      PiperOrigin-RevId: 189069837
      
      * Enforcing that all datasets are batched (and then unbatched in the model) with batch_size >= 1.
      
      PiperOrigin-RevId: 189117178
      
      * Adding regularization to total loss returned from DetectionModel.loss().
      
      PiperOrigin-RevId: 189189123
      
      * Standardize the names of loss scalars (for SSD, Faster R-CNN and R-FCN) in both training and eval so they can be compared on tensorboard.
      
      Log localization and classification losses in evaluation.
      
      PiperOrigin-RevId: 189189940
      
      * Remove negative test from box list ops test.
      
      PiperOrigin-RevId: 189229327
      
      * Add an option to warmup learning rate in manual stepping schedule.
      
      PiperOrigin-RevId: 189361039
      
      * Replace tf.contrib.slim.tfexample_decoder.LookupTensor with object_detection.data_decoders.tf_example_decoder.LookupTensor.
      
      PiperOrigin-RevId: 189388556
      
      * Force regularization summary variables under specific family names.
      
      PiperOrigin-RevId: 189393190
      
      * Automated g4 rollback of changelist 188619139
      
      PiperOrigin-RevId: 189396001
      
      * Remove step 0 schedule since we do a hard check for it after cl/189361039
      
      PiperOrigin-RevId: 189396697
      
      * PiperOrigin-RevId: 189040463
      
      * PiperOrigin-RevId: 189059229
      
      * PiperOrigin-RevId: 189214402

      * Make slim python3 compatible.
      
      * Monir fixes.
      
      * Add TargetAssignment summaries in a separate family.
      
      PiperOrigin-RevId: 189407487
      
      * 1. Setting `family` keyword arg prepends the summary names twice with the same name. Directly adding family suffix to the name gets rid of this problem.
      2. Make sure the eval losses have the same name.
      
      PiperOrigin-RevId: 189434618
      
      * Minor fixes to make object detection tf 1.4 compatible.
      
      PiperOrigin-RevId: 189437519
      
      * Call the base of mobilenet_v1 feature extractor under the right arg scope and set batchnorm is_training based on the value passed in the constructor.
      
      PiperOrigin-RevId: 189460890

      PiperOrigin-RevId: 189601955

      PiperOrigin-RevId: 189606169
      
      * Let the proposal feature extractor function in faster_rcnn meta architectures return the activations (end_points).
      
      PiperOrigin-RevId: 189619301
      
      * Fixed bug which caused masks to be mostly zeros (caused by detection_boxes being in absolute coordinates if scale_to_absolute=True.
      
      PiperOrigin-RevId: 189641294
