Hi,
I have made my own tinyer yolo and trained it and it works with darknet without issues.
But when I compile it and run it on the stick I get a hug error I dont understand.
Can anyone guide me ?
I have attached the model and the weights here.
https://drive.google.com/open?id=1XnNkMyhZp0DBJvDqh_hzI1Fv_roY__r5
Here is the error I get

@ashwinnair14, looks like the issue is @ the app level. I was able to successfully run your model through mvNCProfiler, which means that your graph file is 'syntactically correct'. I do not have your python app, so I tried loading your graph file into https://github.com/movidius/ncappzoo/blob/master/caffe/TinyYolo/run.py, but since the number of outputs in your network is different from the one that's on NCAppZoo I had to hack your 8.prototxt:
Last layer of your 8.prototxt
layer {
name: "conv8"
type: "Convolution"
bottom: "scale7"
top: "conv8"
convolution_param {
num_output: 45
kernel_size: 1
stride: 1
pad: 0
}
}
I added an fc9 to your 8.prototxt
layer {
name: "conv8"
type: "Convolution"
bottom: "scale7"
top: "conv8"
convolution_param {
num_output: 45
kernel_size: 1
stride: 1
pad: 0
}
}
layer {
name: "fc9"
type: "InnerProduct"
bottom: "conv8"
top: "fc9"
inner_product_param {
num_output: 1470
}
}
The app runs fine, but the network doesn't detect any objects (output is a matrix of zeros). As a sanity check, I would recommend retraining your model with an fc layer that has 1470 outputs, and use https://github.com/movidius/ncappzoo/blob/master/caffe/TinyYolo/run.py for inferencing.

Hello @AshwinVijayakumar ,
Thats some great insight Reading your answer I fell I had not given all details of the problem.
I had used the original darknet (https://github.com/pjreddie/darknet) to train my model with 4 classes which is why the last conv layer has 45 outputs.
I have used the scripts in github https://github.com/duangenquan/YoloV2NCS to convert the darknet to caffe model which is y they dont have last FC layer and use their YoloV2NCS/detectionExample/Main.py to run where I get the same error.
Is there an other way to convert the darknet models to NCS so that this is done automatically? Or do I need to train the network with some other framework?
I checked their code and found out that I get an error where the outputs are used to get bounding boxes and perform NMS.
I can probably try to find the error if not.
