OpenVINO validation_app: [warning] No images processed

Question

I'm trying to run OpenVINO Inference Engine sample validation_app. According to OpenVINO IE sample: Validation_app , I've prepared my dataset like this:

<path>/dataset
              /0/image0.bmp
              /1/image1.bmp

When I run validation_app with:

./validation_app -i /home/chan/Desktop/predict_inceptionV3/dataset -m '/home/chan/Desktop/pbModel/IRmodel/PredictModel.xml'

warning comes out:

[ INFO ] InferenceEngine:

    Validation dataset: /home/chan/Desktop/predict_inceptionV3/dataset
    Validation approach: Classification network
[ WARNING ] No images processed

Considering the .bmp image is in 700x460 and the input shape of the .xml file is 1x3x299x299, I tried:

./validation_app -i /home/chan/Desktop/predict_inceptionV3/dataset -m '/home/chan/Desktop/pbModel/IRmodel/PredictModel.xml' --ppType ResizeCrop --ppWidth 299 --ppHeight 299

But the WARNING is still the same.

Does anyone know how to fix it?

Instead of using folder structure - put your images into a single folder and create a text file with content:

image0.bmp 0 image1.bmp 1

use path to file as -i argument for validation app.

If you creating file inside a folder with images - use just image names, if outside this folder - use full path.
