223075771 by lzc: Bring in external fixes. -- 222919755 by ronnyvotel: Bug fix in faster r-cnn model builder. Was previously using `inplace_batchnorm_update` for `reuse_weights`. -- 222885680 by Zhichao Lu: Use the result_dict_for_batched_example in models_lib Also fixes the visualization size on when eval is on GPU -- 222883648 by Zhichao Lu: Fix _unmatched_class_label for the _add_background_class == False case in ssd_meta_arch.py. -- 222836663 by Zhichao Lu: Adding support for visualizing grayscale images. Without this change, the images are black-red instead of grayscale. -- 222501978 by Zhichao Lu: Fix a bug that caused convert_to_grayscale flag not to be respected. -- 222432846 by richardmunoz: Fix mapping of groundtruth_confidences from shape [num_boxes] to [num_boxes, num_classes] when the input contains the groundtruth_confidences field. -- 221725755 by richardmunoz: Internal change. -- 221458536 by Zhichao Lu: Fix saver defer build bug in object detection train codepath. -- 221391590 by Zhichao Lu: Add support for group normalization in the object detection API. Just adding MobileNet-v1 SSD currently. This may serve as a road map for other models that wish to support group normalization as an option. -- 221367993 by Zhichao Lu: Bug fixes (1) Make RandomPadImage work, (2) Fix keep_checkpoint_every_n_hours. -- 221266403 by rathodv: Use detection boxes as proposals to compute correct mask loss in eval jobs. -- 220845934 by lzc: Internal change. -- 220778850 by Zhichao Lu: Incorporating existing metrics into Estimator framework. Should restore: -oid_challenge_detection_metrics -pascal_voc_detection_metrics -weighted_pascal_voc_detection_metrics -pascal_voc_instance_segmentation_metrics -weighted_pascal_voc_instance_segmentation_metrics -oid_V2_detection_metrics -- 220370391 by alirezafathi: Adding precision and recall to the metrics. -- 220321268 by Zhichao Lu: Allow the option of setting max_examples_to_draw to zero. -- 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. -- 220136508 by huizhongc: Add weight equalization loss to SSD meta arch. -- 220125875 by pengchong: Rename label_scores to label_weights -- 219730108 by Zhichao Lu: Add description of detection_keypoints in postprocessed_tensors to docstring. -- 219577519 by pengchong: Support parsing the class confidences and training using them. -- 219547611 by lzc: Stop using static shapes in GPU eval jobs. -- 219536476 by Zhichao Lu: 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. -- 219190083 by Zhichao Lu: Add a second expected_loss_weights function using an alternative expectation calculation compared to previous. Integrate this op into ssd_meta_arch and losses builder. Affects files that use losses_builder.build to handle the returning of an additional element. -- 218924451 by pengchong: Add a new way to assign training targets using groundtruth confidences. -- 218760524 by chowdhery: Modify export script to add option for regular NMS in TFLite post-processing op. -- PiperOrigin-RevId: 223075771

196161788 by Zhichao Lu: Add eval_on_train_steps parameter. Since the number of samples in train dataset is usually different to the number of samples in the eval dataset. -- 196151742 by Zhichao Lu: Add an optional random sampling process for SSD meta arch and update mean stddev coder to use default std dev when corresponding tensor is not added to boxlist field. -- 196148940 by Zhichao Lu: Release ssdlite mobilenet v2 coco trained model. -- 196058528 by Zhichao Lu: Apply FPN feature map generation before we add additional layers on top of resnet feature extractor. -- 195818367 by Zhichao Lu: Add support for exporting detection keypoints. -- 195745420 by Zhichao Lu: Introduce include_metrics_per_category option to Object Detection eval_config. -- 195734733 by Zhichao Lu: Rename SSDLite config to be more explicit. -- 195717383 by Zhichao Lu: Add quantized training to object_detection. -- 195683542 by Zhichao Lu: Fix documentation for the interaction of fine_tune_checkpoint_type and load_all_detection_checkpoint_vars interaction. -- 195668233 by Zhichao Lu: Using batch size from params dictionary if present. -- 195570173 by Zhichao Lu: A few fixes to get new estimator API eval to match legacy detection eval binary by (1) plumbing `is_crowd` annotations through to COCO evaluator, (2) setting the `sloppy` flag in tf.contrib.data.parallel_interleave based on whether shuffling is enabled, and (3) saving the original image instead of the resized original image, which allows for small/medium/large mAP metrics to be properly computed. -- 195316756 by Zhichao Lu: Internal change -- PiperOrigin-RevId: 196161788
