Unable to Convert CycleGAN Model into Intermediate Representation (IR)

• Converted TensorFlow* 1 CycleGAN non-frozen model.
  mo --input_meta_graph cyclegan.model-2002.meta
• Received error:[ FRAMEWORK ERROR ] Cannot load input model: Attempting to use uninitialized value generatorA2B/g_r6_bn2/scale/Adam_1 [[{{node _retval_generatorA2B/g_r6_bn2/scale/Adam_1_0_218}}]]

The model conversion might have failed due to uninitialized variables.  

Possible workarounds are as below: 

• Initialize all variables and reload the weights.  

or

• Freeze the graph and export it to protobuf (.pb) file. Refer to Freezing Custom Models in Python*.

Starting from 2021.3, TensorFlow* 1 is supported with limitations, refer to the Release Notes.
