With Hexagon DSP SDK 3.4.3, I'm following the Tensorflow/Hexagon-NN example at examples/hexagon_nn/tutorials/007-tensorflow-to-hexagon-nn and using the Hexagon NN lib at libs/hexagon_nn/2.6.
I've converted my own TensorFlow net into iv3.c and built graph_app_q (with V=hexagon_ReleaseG_toolv83_v66).
I'm seeing a surprising runtime failure:
output tensor prep fail -9: HIGH:0x5E:107:log.c recalc strategy for v66 failed: HIGH:0x5E:107:log.c execute() failed on node id=1004a err=-1: HIGH:0x5E:107:log.c fail in execute_new(): HIGH:0x5E:107:log.c
The referenced node id corresponds to this line in the generated iv3.c:
APPEND_NODE("net_0/Relu_3/eightbit",0x1004a,OP_QuantizedRelu_8,NN_PAD_NA,inputs_for_1004a,3,outputs_for_1004a,3);
I'm not sure what error code "-9" means. How can I go about diagnosing this? Are there any docs on the error codes?
