Computer Vision SDK 2017.1.163
Ubuntu 16.04
I have successfully converted an Inception V1 TensorFlow model using Model Optimizer. I am now trying to convert a customized squeezenet tensorflow model. Summarize graph output for the frozen graph is as follows:
bazel-bin/tensorflow/tools/graph_transforms/summarize_graph --in_graph=out-256-192.pb
Found 1 possible inputs: (name=input, type=float(1), shape=[1,192,256,3])
No variables spotted.
Found 1 possible outputs: (name=output, op=Cast)
Found 1646509 (1.65M) const parameters, 0 (0) variable parameters, and 0 control_edges
54 nodes assigned to device '/device:CPU:0'Op types used: 112 Const, 64 Identity, 32 BiasAdd, 30 Conv2D, 28 Relu, 10 StridedSlice, 8 ConcatV2, 5 Mul, 4 MaxPool, 3 Pack, 2 Add, 2 Conv2DBackpropInput, 2 Cast, 1 Placeholder, 1 ResizeBilinear, 1 Shape, 1 Sigmoid, 1 Sub
To use with tensorflow/tools/benchmark:benchmark_model try these arguments:
bazel run tensorflow/tools/benchmark:benchmark_model -- --graph=out-256-192.pb --show_flops --input_layer=input --input_layer_type=float --input_layer_shape=1,192,256,3 --output_layer=output
My command line for Model Optimizer was:
python3 /opt/intel/computer_vision_sdk_2017.1.163/mo/model_optimizer_tensorflow/modeloptimizer/scripts/model_optimizer.py --input_model=out-256-192.pb --input=input --output=output --data_type=float32 --input_shape=1,192,256,3 --model_name intel-model
...

Failed to run transform 'create_ir'
WARNING: Failed to run the following transform(s): create_ir
Any advice appreciated.
Thanks,

Hi Julien,
Currently SqueezeNet is unsupported by Model Optimizer for TensorFlow. You have 2 options: use SqueezeNet from Caffe (it's supported by Model Optimizer for Caffe) or wait for the next release of Computer Vision SDK where SqueezeNet in Tensorflow framework will be supported.
Best wishes,
Anna
