Prerequisites

Please answer the following questions for yourself before submitting an issue.

• [YES ] I am using the latest TensorFlow Model Garden release and TensorFlow 2.
• [YES ] I am reporting the issue to the correct repository. (Model Garden official or research directory)
• [YES ] I checked to make sure that this issue has not already been filed.

2. Describe the bug

When exporting fine-tuned model (EfficientDet and MobileNet), I got Warnings / Info telling me: WARNING:tensorflow:Skipping full serialization of Keras layer <object_detection.meta_architectures.ssd_meta_arch.SSDMetaArch object at 0x7f28c027c9e8>, because it is not built. W1121 16:00:38.569402 139816344586048 save_impl.py:78] Skipping full serialization of Keras layer <object_detection.meta_architectures.ssd_meta_arch.SSDMetaArch object at 0x7f28c027c9e8>, because it is not built.

Or: INFO:tensorflow:Unsupported signature for serialization: (([(<tensorflow.python.framework.func_graph.UnknownArgument object at 0x7f27f8886dd8>, TensorSpec(shape=(None, 64, 64, 40), dtype=tf.float32, name='feature_pyramid/0/1')), (<tensorflow.python.framework.func_graph.UnknownArgument object at 0x7f27f8886e48>, TensorSpec(shape=(None, 32, 32, 112), dtype=tf.float32, name='feature_pyramid/1/1')), (<tensorflow.python.framework.func_graph.UnknownArgument object at 0x7f27f8886e10>, TensorSpec(shape=(None, 16, 16, 320), dtype=tf.float32, name='feature_pyramid/2/1'))], False), {}).

I really do not know their meaning. I got these errors in tf2.5 from source and tf2.3 binary.

3. Steps to reproduce

With trained model: from TensorFlow/models/research/: python object_detection/exporter_main_v2.py --input_type="image_tensor" --pipeline_config_path=$MODEL_DIR/pipeline.config --trained_checkpoint_dir=$MODEL_DIR --output_directory=$OUT

5. Additional context

See attached files.

After using exporter_main_v2.py, I tried to use https://github.com/opencv/opencv/tree/master/samples/dnn/tf_text_graph_efficientdet.py (I had to make some changes in order to ensure the compability with tf2). python path/to/tf_text_graph-efficientdet.py --input=./folder/saved_model.pb --output=./opencv_friendly/ --num_classes=1 it outputs:

I've seen similar messages when exporting models as well. However, the models end up working as expected when I run inference, so it shouldn't be a big deal (TF does tend to be rather verbose with its warnings). Have you running the model without 3rd party tools? I know you mentioned making changes to the opencv script to ensure TF2 compatibility, but I've only seen the "Failed to parse GraphDef file" + "google.protobuf.message.DecodeError: Error parsing message" combo when I've tried loading a TF2 model using a script that expected a TF1 frozen graph.

[fbens47]

The only changes I made were the use tf.io instead of tf.python_io from tfv1. But now, I tested on pre-trained (i.e: directly from Object detection zoo) and I got the same errors. I'll give a Try for inference without third party tools. But I'll need cv::Net::readNetFromTensorflow... Plus, in tensorflow from source (2.5). The bazel command bazel-bin/tensorflow/tools/graph_transforms/summarize_graph (as graph_transform) fails.

[SamLee514]

Hm, I'm not familiar with the built-from-source version, unfortunately. But you should be able to evaluate your models without a hitch in 2.3 at least (the colab notebooks are especially helpful here).

[fbens47]

Actually, the TF2 models don't work for now with OpenCV.

[rlm96]

I have same problem. In the inference process it fails the detection assigning random classes to objects that don´t belong to that class (i.e. in a chess dataset assigning queen and king to towers).
