Refer to the [Model Optimizer](https://docs.openvino.ai/latest/openvino_docs_MO_DG_Deep_Learning_Model_Optimizer_DevGuide.html) documentation to learn how to obtain IR model. The tool analyzes the following parameters: Parameter | Explanation | Unit of Measurement| Example ---|---|---|--- GFlop | Total number of floating-point operations required to infer a model. Summed up over known layers only.| Number of operations| 0.88418 × 10⁹ GIop | Total number of integer operations required to infer a model. Summed up over known layers only.| Number of operations| 0.86748 × 10⁹ Total number of weights|Total number of trainable model parameters excluding custom constants. Summed up over known layers only.|Number of weights| 3.489 × 10⁶ Minimum Memory Consumption |Theoretical minimum of memory used by a model for inference given that the memory is reused as much as possible. Minimum Memory Consumption does not depend on weights.|Number of activations|2.408 × 10⁶ Maximum Memory Consumption |Theoretical maximum of memory used by a model for inference given that the memory is not reused, meaning all internal feature maps are stored in the memory simultaneously. Maximum Memory Consumption does not depend on weights.|Number of activations| 26.833 × 10⁶ Sparsity |Percentage of zero weights| Percentage|20% ## ⚙️ Command-Line Interface Run this command to get a list of available arguments: ```shell python3 model_analyzer.py -h ``` Argument | Explanation |Example ---|---|--- `-h`, `--help`|Displays help message.|`N/A`| `-m`, `--model`|Path to an .xml file of the Intermediate Representation (IR) model.

## 💻 Run Model Analyzer This is an example of running Model Analyzer with mobilenet-v2 model: 1. Install [OpenVINO Toolkit Developer Package](https://pypi.org/project/openvino-dev/): ```shell python3 pip install openvino-dev ``` 2. Clone the repository: ```sh git clone git@github.com:openvinotoolkit/model_analyzer.git cd model_analyzer ``` 2. Download a model with [OMZ Model Downloader](https://docs.openvino.ai/latest/omz_tools_downloader.html): ```shell omz_downloader --name mobilenet-v2 ``` 3. Convert the model to IR with [Model Converter](https://docs.openvino.ai/latest/omz_tools_downloader.html#model_converter_usage): ```shell omz_converter --name mobilenet-v2 ``` 4. Run Model Analyzer: ```sh python3 model_analyzer.py --model ./public/mobilenet-v2/FP16/mobilenet-v2.xml --ignore-unknown-layers ``` You will get the following output: ```sh OUTPUT: [ INFO ] Loading network files: public/mobilenet-v2/FP16/mobilenet-v2.xml public/mobilenet-v2/FP16/mobilenet-v2.bin Warning, GOPS for layer(s) wasn't counted - ReduceMean [ INFO ] GFLOPs: 0.8842 [ INFO ] GIOPs: 0.0000 [ INFO ] MParams: 3.4889 [ INFO ] Sparsity: 0.0001 [ INFO ] Minimum memory consumption: 2.4084 [ INFO ] Maximum memory consumption: 26.8328 [ INFO ] Guessed type: classificator [ INFO ] Network status information file name: /home/user/model_analyzer/model_report.csv ``` Find the instructions for contributors in the [DEVELOPER.md](https://github.com/openvinotoolkit/model_analyzer/blob/master/DEVELOPER.md) document. ## ⚠️ Limitations 1. Note that Model Analyzer provides approximate theoretical information, as some of the layers may be ignored due to the model structure. 2. At the analysis stage, Model Analyzer can detect layers for which no information is available. Use `--ignore-unknown-layers` option to avoid errors. Feel free to submit your suggestions on how to analyze these layers.
