class="devsite-article-body clearfix "> This guide introduces you to the process of running a LiteRT (short for Lite Runtime) model on-device to make predictions based on input data. This is achieved with the LiteRT interpreter, which uses a static graph ordering and a custom (less-dynamic) memory allocator to ensure minimal load, initialization, and execution latency. LiteRT inference typically follows the following steps: <ol> <li>Loading a model: load the <code translate="no" dir="ltr">.tflite</code> model into memory, which contains the model's execution graph.</li> <li>Transforming data: Transform input data into the expected format and dimensions. Raw input data for the model generally does not match the input data format expected by the model. For example, you might need to resize an image or change the image format to be compatible with the model.</li> <li>Running inference: Execute the LiteRT model to make predictions. This step involves using the LiteRT API to execute the model. It involves a few steps such as building the interpreter, and allocating tensors.</li> <li>Interpreting output: Interpret the output tensors in a meaningful way that's useful in your application. For example, a model might return only a list of probabilities. It's up to you to map the probabilities to relevant categories and format the output.</li> </ol> This guide describes how to access the LiteRT interpreter and perform an inference using C++, Java, and Python. <h2 id="supported-platforms" data-text="Supported platforms" tabindex="-1">Supported platforms</h2> TensorFlow inference APIs are provided for most common mobile and embedded platforms such as <a href="#android">Android</a>, <a href="#ios">iOS</a> and <a href="#linux">Linux</a>, in <a href="https://ai.google.dev/edge/api/index#litert_api">multiple programming languages</a>. In most cases, the API design reflects a preference for performance over ease of use. LiteRT is designed for fast inference on small devices, so the APIs avoid unnecessary copies at the expense of convenience. Across all libraries, the LiteRT API lets you to load models, feed inputs, and retrieve inference outputs. <h3 id="android" data-text="Android Platform" tabindex="-1">Android Platform</h3> On Android, LiteRT inference can be performed using either Java or C++ APIs. The Java APIs provide convenience and can be used directly within your Android Activity classes. The C++ APIs offer more flexibility and speed, but may require writing JNI wrappers to move data between Java and C++ layers. See the <a href="#run-c">C++</a> and <a href="#run-java">Java</a> sections for more information, or follow the <a href="https://ai.google.dev/edge/litert/android">Android quickstart</a>.  <h3 id="ios" data-text="iOS Platform" tabindex="-1">iOS Platform</h3> On iOS, LiteRT is available in <a href="https://github.com/tensorflow/tensorflow/tree/master/tensorflow/lite/swift">Swift</a> and <a href="https://github.com/tensorflow/tensorflow/tree/master/tensorflow/lite/objc">Objective-C</a> iOS libraries. You can also use <a href="https://github.com/tensorflow/tensorflow/blob/master/tensorflow/lite/c/c_api.h">C API</a> directly in Objective-C code. See the <a href="#run-swift">Swift</a>, <a href="#run-objc">Objective-C</a>, and <a href="#run-c">C API</a> sections, or follow the <a href="https://ai.google.dev/edge/litert/ios/quickstart">iOS quickstart</a>. <h3 id="linux" data-text="Linux Platform" tabindex="-1">Linux Platform</h3> On Linux platforms, you can run inferences using LiteRT APIs available in <a href="#run-c">C++</a>. <h2 id="load-model" data-text="Load and run a model" tabindex="-1">Load and run a model</h2> Loading and running a LiteRT model involves the following steps: <ol> <li>Loading the model into memory.</li> <li>Building an <code translate="no" dir="ltr">Interpreter</code> based on an existing model.</li> <li>Setting input tensor values.</li> <li>Invoking inferences.</li> <li>Outputting tensor values.</li> </ol> <h3 id="run-java" data-text="Android (Java)" tabindex="-1">Android (Java)</h3> The Java API for running inferences with LiteRT is primarily designed for use with Android, so it's available as an Android library dependency: <code translate="no" dir="ltr">com.google.ai.edge.litert</code>. In Java, you'll use the <code translate="no" dir="ltr">Interpreter</code> class to load a model and drive model inference. In many cases, this may be the only API you need. You can initialize an <code translate="no" dir="ltr">Interpreter</code> using a FlatBuffers (<code translate="no" dir="ltr">.tflite</code>) file: <div></div><devsite-code><pre class="devsite-click-to-copy" translate="no" dir="ltr" is-upgraded syntax="Java"><code translate="no" dir="ltr">public Interpreter(@NotNull File modelFile); </code></pre></devsite-code> Or with a <code translate="no" dir="ltr">MappedByteBuffer</code>: <div></div><devsite-code><pre class="devsite-click-to-copy" translate="no" dir="ltr" is-upgraded syntax="Java"><code translate="no" dir="ltr">public Interpreter(@NotNull MappedByteBuffer mappedByteBuffer); </code></pre></devsite-code> In both cases, you must provide a valid LiteRT model or the API throws <code translate="no" dir="ltr">IllegalArgumentException</code>. If you use <code translate="no" dir="ltr">MappedByteBuffer</code> to initialize an <code translate="no" dir="ltr">Interpreter</code>, it must remain unchanged for the whole lifetime of the <code translate="no" dir="ltr">Interpreter</code>. The preferred way to run inference on a model is to use signatures - Available for models converted starting Tensorflow 2.5 <div></div><devsite-code><pre class="devsite-click-to-copy" translate="no" dir="ltr" is-upgraded syntax="Java"><code translate="no" dir="ltr">try (Interpreter interpreter = new Interpreter(file_of_tensorflowlite_model)) { Map<String, Object> inputs = new HashMap<>(); inputs.put("input_1", input1); inputs.put("input_2", input2); Map<String, Object> outputs = new HashMap<>(); outputs.put("output_1", output1); interpreter.runSignature(inputs, outputs, "mySignature"); } </code></pre></devsite-code> The <code translate="no" dir="ltr">runSignature</code> method takes three arguments: <ul> <li>Inputs : map for inputs from input name in the signature to an input object.</li> <li>Outputs : map for output mapping from output name in signature to output data.</li> <li>Signature Name (optional): Signature name (Can be left empty if the model has single signature).</li> </ul> Another way to run inferences when the model doesn't have a defined signatures. Simply call <code translate="no" dir="ltr">Interpreter.run()</code>. For example: <div></div><devsite-code><pre class="devsite-click-to-copy" translate="no" dir="ltr" is-upgraded syntax="Java"><code translate="no" dir="ltr">try (Interpreter interpreter = new Interpreter(file_of_a_tensorflowlite_model)) { interpreter.run(input, output); } </code></pre></devsite-code> The <code translate="no" dir="ltr">run()</code> method takes only one input and returns only one output. So if your model has multiple inputs or multiple outputs, instead use: <div></div><devsite-code><pre class="devsite-click-to-copy" translate="no" dir="ltr" is-upgraded syntax="Java"><code translate="no" dir="ltr">interpreter.runForMultipleInputsOutputs(inputs, map_of_indices_to_outputs); </code></pre></devsite-code> In this case, each entry in <code translate="no" dir="ltr">inputs</code> corresponds to an input tensor and <code translate="no" dir="ltr">map_of_indices_to_outputs</code> maps indices of output tensors to the corresponding output data. In both cases, the tensor indices should correspond to the values you gave to the <a href="https://ai.google.dev/edge/litert/models/convert">LiteRT Converter</a> when you created the model. Be aware that the order of tensors in <code translate="no" dir="ltr">input</code> must match the order given to the LiteRT Converter. The <code translate="no" dir="ltr">Interpreter</code> class also provides convenient functions for you to get the index of any model input or output using an operation name: <div></div><devsite-code><pre class="devsite-click-to-copy" translate="no" dir="ltr" is-upgraded syntax="Java"><code translate="no" dir="ltr">public int getInputIndex(String opName); public int getOutputIndex(String opName); </code></pre></devsite-code> If <code translate="no" dir="ltr">opName</code> is not a valid operation in the model, it throws an <code translate="no" dir="ltr">IllegalArgumentException</code>. Also beware that <code translate="no" dir="ltr">Interpreter</code> owns resources. To avoid memory leak, the resources must be released after use by: <div></div><devsite-code><pre class="devsite-click-to-copy" translate="no" dir="ltr" is-upgraded syntax="Java"><code translate="no" dir="ltr">interpreter.close(); </code></pre></devsite-code> For an example project with Java, see the <a href="https://github.com/google-ai-edge/litert-samples/tree/main/examples/object_detection/android">Android object detection example app</a>. <h4 id="supported_data_types" data-text="Supported data types" tabindex="-1">Supported data types</h4> To use LiteRT, the data types of the input and output tensors must be one of the following primitive types: <ul> <li><code translate="no" dir="ltr">float</code></li> <li><code translate="no" dir="ltr">int</code></li> <li><code translate="no" dir="ltr">long</code></li> <li><code translate="no" dir="ltr">byte</code></li> </ul> <code translate="no" dir="ltr">String</code> types are also supported, but they are encoded differently than the primitive types. In particular, the shape of a string Tensor dictates the number and arrangement of strings in the Tensor, with each element itself being a variable length string. In this sense, the (byte) size of the Tensor cannot be computed from the shape and type alone, and consequently strings cannot be provided as a single, flat <code translate="no" dir="ltr">ByteBuffer</code> argument. If other data types, including boxed types like <code translate="no" dir="ltr">Integer</code> and <code translate="no" dir="ltr">Float</code>, are used, an <code translate="no" dir="ltr">IllegalArgumentException</code> will be thrown. <h5 id="inputs" data-text="Inputs" tabindex="-1">Inputs</h5> Each input should be an array or multi-dimensional array of the supported primitive types, or a raw <code translate="no" dir="ltr">ByteBuffer</code> of the appropriate size. If the input is an array or multi-dimensional array, the associated input tensor will be implicitly resized to the array's dimensions at inference time. If the input is a ByteBuffer, the caller should first manually resize the associated input tensor (via <code translate="no" dir="ltr">Interpreter.resizeInput()</code>) before running inference. When using <code translate="no" dir="ltr">ByteBuffer</code>, prefer using direct byte buffers, as this allows the <code translate="no" dir="ltr">Interpreter</code> to avoid unnecessary copies. If the <code translate="no" dir="ltr">ByteBuffer</code> is a direct byte buffer, its order must be <code translate="no" dir="ltr">ByteOrder.nativeOrder()</code>. After it is used for a model inference, it must remain unchanged until the model inference is finished. <h5 id="outputs" data-text="Outputs" tabindex="-1">Outputs</h5> Each output should be an array or multi-dimensional array of the supported primitive types, or a ByteBuffer of the appropriate size. Note that some models have dynamic outputs, where the shape of output tensors can vary depending on the input. There's no straightforward way of handling this with the existing Java inference API, but planned extensions will make this possible. <h3 id="run-swift" data-text="iOS (Swift)" tabindex="-1">iOS (Swift)</h3> The <a href="https://github.com/tensorflow/tensorflow/tree/master/tensorflow/lite/swift">Swift API</a> is available in <code translate="no" dir="ltr">TensorFlowLiteSwift</code> Pod from Cocoapods.
