# annInferenceApp - Client Application

This Sample Inference Application supports:

* connect to [inference_server_app](../server_app#mivisionx-inference-server) 
  * queries number of GPUs on the server
  * queries pre-loaded neural network models on the server
  * upload pre-trained CAFFE models (optional)
  * specify input width and height dimensions
  * browse and pick deploy.prototxt and weights.caffemodel files
  * specify input preprocesor values for normalization (if needed)
  * specify input channel order (RGB or BGR)
  * optionally, you can publish your neural network for use by others
    * select "PublishAs"
    * give a name to your model
    * type password (default passowrd of `inference_server_app` is "**radeon**")
    
* pick a CNN model, if upload option is not used

* run inference on images from a folder
  * browse and pick labels (i.e., synset words for each output label)
  * browse and pick input images to be classified
  * optionally, pick list of input images from a .txt or .csv file
  * optionally, specify max number of images to be processed from folder or image list

If you want to run a simple test, use [annInferenceApp.py](annInferenceApp.py) (a python script) to simply pick a network model to classify local images.
````
% python annInferenceApp.py [-v] -host:<hostname> -port:<port> -model:<modelName>
                            [-synset:<synset.txt>] [-output:<output.csv>]
                            <folder>|<file(s)>

* Using QMake

  If you want to avoid installing QtCreator application (Qt creator app is only needed for debugging and designing purposes), you can also build the app using QMake
  ````
    sudo apt-get install qt5-qmake
    cd MIVisionX/apps/cloud_inference/client_app/
    qmake -o Makefile annInferenceApp.pro
  ````
  The above qmake command will generate a Makefile for the application, which can be used to build the application. When your application is successfully built, run the app as you are running ordinary c application.
  ````
    make
    ./annInferenceApp
  ````
