hi,

i am following this link https://docs.openvinotoolkit.org/2020.1/_docs_MO_DG_prepare_model_convert_model_tf_specific_Convert_... 

in the third step i was getting AssertionError  

 

 

frozen = tf.graph_util.convert_variables_to_constants(sess, sess.graph_def, ['shadow/LSTMLayers/transpose_time_major'])

 

 

 shadow/LSTMLayers/transpose_time_major is not in graph

i changed it to below 

 

 

frozen = tf.graph_util.convert_variables_to_constants(sess, sess.graph_def, ['shadow_net/sequence_rnn_module/stack_bidirectional_rnn/cell_0/bidirectional_rnn/fw/fw/while/Identity_2'])

 

 

and frozen_graph is generated, i am trying to use this frozen graph with this link example https://github.com/opencv/opencv/blob/master/samples/dnn/text_detection.cpp 

and opencv throws error

i have trained my model from https://github.com/MaybeShewill-CV/CRNN_Tensorflow.git

i am new to tensorflow , can anyone please have a look  

i have uploaded my model to drive https://drive.google.com/drive/folders/1wgFcC3a5jMqcRFvKmj4XFAv_b7ATt9xV?usp=sharing please have a look.

Hi,

https://github.com/MaybeShewill-CV/CRNN_Tensorflow has not been validated for the C++ Text Detection sample.

i also tried to convert it into IR, but got some error

 

Model Optimizer version:

Hi Amit,


Please provide the command given to Model Optimizer to convert your trained model to Intermediate Representation (IR), and environment details (versions of OS, TensorFlow, Python, CMake, etc.).


Regards,

Munesh

hi ,

command i tried is 

 

python mo_tf.py --input_model E:\CRNN_Tensorflow-case\frozen_graph_test.pb --reverse_input_channels   --data_type FP32 --input_shape="[1,32,100,3]"  --output_dir IR

 

 

 i trained this model in ubuntu 18.04, tensoflow-gpu 1.15, python 3.7

and to convert the frozen_graph i used

windows 10 x64bit machine,

tensorflow-cpu 1.15,

python 3.7

cmake 3.14.5

i have also converted a tensorflow ssd object detection model to IR and that is working fine.
