Hi,

Environment:

Os: Ubuntu 18.04

Model Optimizer version: 2019.2.0-436-gf5827d4

I'm trying to convert EAST TensorFlow implementation model, that can be download in this link, to IR openvino model. This implementation can be found here. When I tried to run the following code:

python3 /opt/intel/openvino/deployment_tools/model_optimizer/mo_tf.py --input_meta_graph east_icdar2015_resnet_v1_50_rbox/model.ckpt-49491.meta

The following error was presented:

Model Optimizer arguments:

        - Path to the Input Model:      None
        - Path for generated IR:        /root/.
        - IR output name:       model.ckpt-49491

I've searched in the openvino forum to find a solution but I'm not able to solve. Can you help me?

 

Best regards,

Hi Felipe,

The EAST model is currently not supported by the OpenVINO toolkit. However, there is a feature request for the development team to consider and potentially enable it in a future software release. We do have a text detection/recognition demo and models available, see the demo documentation here.

Please let me know if you have additional questions.

Regards,

Jesus

Hi Jesus,

Thanks for your explanation. I am interested in porting EAST to openvino. Can I help development team to implement this feature, if possible? I don't know how exactly to do that but if you give me the directions, I can help. 

Regards,

Felipe Ximenes
