Hi,

I am trying to convert my tensorflow model into DLC using this command.

snpe-tensorflow-to-dlc --graph=onet_landmark.pb --input_dim "onet/input" 48,48,3 --out_node onet/prob1 --out_node onet/conv6-2/conv6-2 --out_node onet/conv6-3/conv6-3 --dlc=onet_landmark.dlc --verbose

But some of the nodes in graph are not consumed by the DLC converter.

Please clarify Is these layers are not supported by SNPE or something that I missed that gave me wrong output?

Thanks in Advance,

Hi
You can go through the below link which lists out all the layers and activation functions supported by SNPE,
https://developer.qualcomm.com/docs/snpe/network_layers.html

Using the below command you can get the DLC model file excluding the unsupported layers. Check if the model works as expected,
snpe-tensorflow-to-dlc --graph=onet_landmark.pb --input_dim "onet/input" 48,48,3 --out_node onet/prob1 --out_node onet/conv6-2/conv6-2 --out_node onet/conv6-3/conv6-3 --dlc=onet_landmark.dlc --verbose --allow_unconsumed_nodes
To give more details for your error, kindly provide us the architecture of the model you are working on.
