+# OpenVINO™ Inference Interpreter 
+Interpreter samples to parse OpenVINO™ inference outputs.
+
+## Models supported from interpreter samples
+There are detection and image classification examples.

+
+You can find more OpenVINO™ Trained Models [here](https://docs.openvinotoolkit.org/latest/omz_models_intel_index.html)
+To run the inference with OpenVINO™, the model format should be Intermediate Representation(IR). 
+For the Caffe/TensorFlow/MXNet/Kaldi/ONNX models, please see the [Model Conversion Instruction](https://docs.openvinotoolkit.org/latest/openvino_docs_MO_DG_prepare_model_convert_model_Converting_Model.html)
+
+You need to implement your own interpreter samples to support the other OpenVINO™ Trained Models.

+  # datum create -o <proj_dir>
+  # datum model add -l <launcher> -p <proj_dir> --copy -- -d <path_to_xml> -w <path_to_bin> -i <path_to_interpreter_script>
+  # datum add path -p <proj_dir> -f <format> <path_to_dataset>
+  # datum model run -p <proj_dir> -m model-0
+  #
+  # Examples
+  # Detection> ssd_mobilenet_v2_coco
+  source /opt/intel/openvino/bin/setupvars.sh
+  cd datumaro/plugins/openvino
+  datum create -o proj_ssd_mobilenet_v2_coco_detection
