Hi ,

I want to convert the tensorflow model into DLC by using " snpe-tensorflow-to-dlc " tool . The command is as follows:

snpe-sdk$:  snpe-tensorflow-to-dlc --graph $SNPE_ROOT/models/inception_v3/tensorflow/inception_v3_2016_08_28_frozen.pb --input_dim input "1,299,299,3" --out_node "InceptionV3/Predictions/Reshape_1" --dlc /home/tcs/Downloads/Narendar/snpe-1.24.0.256/models/inception_v3/dlc/inception_v3.dlc --allow_unconsumed_nodes --verbose   

However, Im getting the following error saying as Memory Error:

2019-04-15 11:30:02,303 - 322 - INFO - INFO_TF_BUILDING_INPUT_LAYER: Building layer (INPUT) with node: input, shape [1, 299, 299, 3]

Hi bnarendar89,

This error may causes because of non-availability of enough memory in your system which occuring while loading the required data into the main memory. Before running the conversion please make sure you have enough free memory available in your system.
