Input nodes missing in frozen graph

[sjmjk429]

With TensorFlow v1.9.0, I went through the training instructions and produced the following .pbtxt and checkpoint files:

I then tried to freeze the graph:

$ freeze_graph \
    --input_graph=./logs/graph.pbtxt \
    --input_binary=false \
    --input_checkpoint=./logs/model.ckpt-120000 \
    --output_graph=frozen_graph.pb \
    --output_node_names=ssd300/Reshape_13,ssd300/Reshape_12

This seemed to successfully produce a frozen graph file:
105203994 May 21 13:55 frozen_graph.pb

When I inspected the frozen_graph.pb file, it appears that input nodes are missing from the graph:

$ decent_q inspect --input_frozen_graph frozen_graph.pb 

Op types used: 167 Const, 71 Identity, 35 BiasAdd, 35 Conv2D, 23 Relu, 15 Reshape, 12 Transpose, 12 StridedSlice, 12 Pack, 5 MaxPool, 2 Mul, 2 ConcatV2, 1 Maximum, 1 QueueDequeueManyV2, 1 FIFOQueueV2, 1 Rsqrt, 1 SpaceToBatchND, 1 Square, 1 Sum, 1 BatchToSpaceND
 
No inputs found.
Found 2 possible outputs: (name=ssd300/Reshape_12, op=Reshape) (name=ssd300/Reshape_13, op=Reshape) 

Any ideas as to why the input node(s) are missing? What should the input nodes for this model be?

Thank you.

where did you feed the input image?
