case of multi input node base Tensorflow quantizer run error

[rokmc612]

Hi,

compiled tensorflow framework at Jupyter environment. and I used by https://github.com/tegg89/SRCNN-Tensorflow sample code.

but, issued th error when compile to quantize run. for the sample tensorflow code have a couple of input node and one output node.

would you pls advice to multi input node case compile flow:

for the sample code

Step 2 result

Running with protoBuffer: /home/mluser/share/SRCNN-Tensorflow-master/checkpoint/srcnn_21/SRCNN.model/freeze_graph.pb
Running with quantInfo: /opt/models/tensorflow/quantization_fix_info.txt
Running with inputNode: images,labels
Running with outputNode: Mean
Running with inputShape: 33,33:21,21
Running with means: 104,107,123

Step 3. Run the Quantizer

!decent_q inspect --input_frozen_graph $protoBuffer

Op types used: 7 Const, 6 Identity, 3 Add, 3 Conv2D, 2 Placeholder, 2 Relu, 1 Mean, 1 Square, 1 Sub

Found 2 possible inputs: (name=images, type=float(1), shape=[?,33,33,1]) (name=labels, type=float(1), shape=[?,21,21,1])
Found 1 possible outputs: (name=Mean, op=Mean)

!decent_q quantize
--input_frozen_graph $protoBuffer
--input_nodes $inputNode
--output_nodes $outputNode
--input_shapes ?,$inputShape,1
--output_dir $MODELDIR
--input_fn util.input_fn
--method 1
