Shell gets stuck when Standalone graph_app in hexagon nnlib is ran

Question

Shell was not responding when i issued this command.

/data/local/graph_app --flag 299 299 3 1 0 0 1 NULL 0 1 0 inputfile /data/local/tmp/img_299x299.bmp

got description info from helper optargs

Usage: testapp [--flag flagopt] [inputfile [inputfile...]]
           flag name      type   default  function
              height       int         0  Height of the input data. 0 == autodetect-square
               width       int         0  Width of the input data. 0 == autodetect-square
               depth       int         3  Depth of the input data
               iters       int         1  Number of times to run each input
            perfdump       int         0  Generate performance dump
                 pmu       int         0  Get Performance Monitor Unit information
         elementsize       int         1  Element Size (uint8==1,float==4)
       layer_reorder    string      NULL  Reorder depth layers. ("210" changes RGB to BGR)
       pprint_floats       int         0  Pretty-Print output as floats
     pprint_imagenet       int         1  Pretty-print output, getting top 5 values and use imagenet categories
               debug       int         0  Debug verbosity level. Higher numbers get more verbosity

Did i miss anything, let me know , I used graphinit_med.c just to check its working and there is no description on what this model does.

thanks,

There is no document on using standalone graph_app, After going through the code got to make it working:

data/hvx_tf/graph_app --height 299 --width 299 --depth 3 --iters 1 --perfdump 0 --pmu 0 --elementsize 1 --pprint_floats 0 --pprint_imagenet 1 --debug 0 /data/local/tmp/keyboard_299x299.dat

There is still caveat as you can see below logs:

I will update the answer, once I get the standalone app predict the sample image with highest accuracy.
