Object detection AttributeError: use_combined_nms

[hsparrow]

System information

• What is the top-level directory of the model you are using: object_detection
• Have I written custom code (as opposed to using a stock example script provided in TensorFlow): no
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): OS X 10.14.1
• TensorFlow installed from (source or binary): pip
• TensorFlow version (use command below): 1.15.0
• Bazel version (if compiling from source):
• CUDA/cuDNN version: no
• GPU model and memory: no GPU
• Exact command to reproduce:

Describe the problem

Previously, I've successfully trained a custom detector with an older version of training executable script but the same configuration, which now failed on tf.contrib. Now I'm trying to reproduce it. The custom detector is based on pre-trained ssd_inception_v2_coco with object detection API, the error AttributeError: use_combined_nms occurs as following traceback shows. No modification to the object_detection/model_main.py script. It seems there is no use_combined_nms attribute set in the postprocessing config.

Source code / logs

Training command:

python3 model_main.py --alsologtostderr --model_dir=training/ --pipeline_config_path=training/ssd_inception_v2_coco.config --num_train_steps=10 --sample_1_of_n_eval_examples=1

Having the same issue with trainning of mobilenet_v2 and mobilenet_v3. I think itś related to #6138

Which commit of https://github.com/tensorflow/models are you at?

I tested the repo at e97e22d and I could generate an SSD graph.

I tried to repro this but I can't find in the directory: training/ssd_inception_v2_coco.config
