model optimzer in intel open vino - tensorflow

Question

I used
import tensorflow as tf
model = tf.keras.models.load_model('model.h5')
tf.saved_model.save(model,'model')
for saving my image classification model (tensorflow version on google colab = 2.9.2, intel open vino version[Development Tools] = 2021.4.2 LTS)

I am getting this kind of error even after I downloaded
install_prerequirement/install_prerequisites_tf2.bat
need help

Answer 1

Your error seems to indicate the mismatch between the TensorFlow version used to load GraphDef file. From my replication, I am able to generate the Intermediate Representation (IR) files using TensorFlow 2.5.3 version. Here is the full Model Optimizer command used:
mo_tf.py --saved_model_dir <path_to_model\IMGC.h5_to_saved_model.pb> --input_shape [1,320,240,3] --output_dir <path_for_output_files>
