Tensorflow model exporter error - Cannot infer shapes or values for node "image_padding/Ceil_1"

Moosa__Azmath — Wed, 22 Apr 2020 05:58:02 GMT

I am trying to export a frozen inference graph pb file. It is a custom bbox detection network with inception v1 blocks. While running the model optimizer, I am getting some errors. The graph was trained and exported from tf v1.10. I want to know how I can debug this model and get it exported.

The command line I used

/opt/intel/openvino/deployment_tools/model_optimizer/mo_tf.py --input_model /data/work/face-rec/face-rec/src/assets/faceboxes-model.pb --input_shape "(1,1024,1024,3)" --input image_tensor  --output_dir ./ --log_level=DEBUG

The error that I am getting is as follows:

I think I need to override the DT_DOUBLE to Float. Could anyone guide me on how I can do that?

Hi Azmath,

Can you please confirm if the model is one of the supported topologies of tensorflow. For face detection problem kindly refer to Interactive face detection demo.

Best Regards,

Surya

Is this issue solved? If yes, how did you solve this?

I'm also facing a similar kind of issue.
