Help using res10 ssd for face detection

Hi,

 

I tried to use caffemodel used by OpenCV dnn face detector (here).

 

When I use mvNCCheck then NCS hangs after inferencing:

 

 

mvNCCheck deploy.prototxt -w res10_300x300_ssd_iter_140000.caffemodel -s 12 -is 300 300 -cs 2,1,0

 

/usr/lib/python3.5/importlib/_bootstrap.py:222: RuntimeWarning: compiletime version 3.4 of module 'tensorflow.python.framework.fast_tensor_util' does not match runtime version 3.5

 

return f(*args, *_kwds)

 

/usr/lib/python3.5/importlib/_bootstrap.py:222: RuntimeWarning: builtins.type size changed, may indicate binary incompatibility. Expected 432, got 412

 

return f(_args, **kwds)

I tried also to compile the graph and inferencing: same result.

@saveriop Hi, just wondering if this is in a virtual machine (on windows 10) or physical machine and which NCSDK version you are using. Thanks.

@saveriop @renhanchi @Slavastas Thanks for reporting this. I tried running the same network on my bench and it seems to hang with a dispatchEventReceived() Read error -4 error and then hangs. The same issue seemed to occur when I tested another user's custom resnet50 model. I am not sure if it is related or what the root cause is, but if I make any progress I'll give you guys an update. Thanks.

Encountering a similar error so I went ahead and put the device in verbose logging mode

 

( - global_set_option(movi.GlobalOption.RW_LOG_LEVEL, 0) ) and did trace (see below) to see if it helps in the troubleshooting process. Critical error in my project so any help or thoughts would be greatly appreciated

 

Thank you!!!
