Hi,
I would like help to convert my TF model into IR Format.
now if I use the mo_tf.py script with specifying the output node parameter to convert my model, I get the following error:

Can anyone help me with the conversion of my model to IR format?

Hello,
Thanks for reaching out. It's unclear what the problem could be without many details of the model and commands used to convert. If you can please share more information about your model, is it an object/classification model, if custom model what type of layers does the model use, command given to the Model Optimizer to convert model. If possible to share model files for us to replicate and find possible mistake (files can be shared via Private Message).
Also any details about your environment are welcome (for example OS, versions of Python, TF, CMake, etc.).
Regards,
Luis

Hello,
This is a Text Recognition Model.
command given to the Model Optimizer to convert model :
python3 python3 /opt/intel/openvino/deployment_tools/model_optimizer/mo_tf.py --input_model frozen_model/LPRecog_model_updated_mxpl_mul_64_hvshear_channels_last.pb --input_shape [1,128,256,3] --input=input_placeholder --output=output_nodes/CTCBeamSearchDecoder --log_level=DEBUG
Environment Details are as below:
OS: Ubuntu 16.04 LTS
Version of python: Python 3.5.2
TF Version: 1.14.0
cmake version 3.16.2

Hi,
I have the same problem with converting model from TF to IR with CTCBeamSearchDecoder openvino-2021.2.
Could you help me with this problem?
