I am trying to convert an EfficientDet_D0 model to OpenVINO.
python3 /opt/intel/openvino_2021.3.394/deployment_tools/open_model_zoo/tools/downloader/downloader.py --name efficientdet-d0-tf
python3 /opt/intel/openvino_2021.3.394/deployment_tools/open_model_zoo/tools/downloader/converter.py \
--name efficientdet-d0-tf --mo /opt/intel/openvino_2021.3.394/deployment_tools/model_optimizer
The commands lead to the error:

Second method seems to work using
python3 $MO_ROOT/mo.py \
--input_shape=[1,512,512,3] \
--input=image_arrays \
--reverse_input_channels \
--input_model savedmodeldir/efficientdet-d0_frozen.pb \
--transformations_config $MO_ROOT/extensions/front/tf/automl_efficientdet.json
This is taken from https://github.com/openvinotoolkit/open_model_zoo/blob/master/models/public/efficientdet-d0-tf/model.yml#L113 .
Is there a way to use the model.yml directly to generate the model?

Hi mfoglio,
Greetings to you.
I am glad that you can configure the OpenVINO Model Optimizer. Other than using the converter.py you also can convert your model into the IR representation using the Model Optimizer script. Hence, you can use a specific script to convert the Tensorflow Model into the IR which mo_tf.py.
Furthermore, I have tested the same workaround as you using the converter.py and getting the same issue. I will discuss this with the developer and update you with the information soon. It might be some configuration issues that are not compatible between the specific model and the converter.
Meanwhile, the .yml file cannot be used directly to generate the model. Only Model Optimizer or converter.py can be used.
Regards,
Aznie

Thank you. Also, the second method actually generates a model that returns all zeros. I am not sure if I am using it the wrong way. More here: https://community.intel.com/t5/Intel-Distribution-of-OpenVINO/Model-returns-all-zeroes/m-p/1272176#M23454

Problem solved: there is no need to normalize the image by dividing by 255.

Hi mgoglio,
This thread will no longer be monitored since this issue has been resolved. If you need any additional information from Intel, please submit a new question.
