+/// C API for TensorFlow Lite.
+///
+/// The API leans towards simplicity and uniformity instead of convenience, as
+/// most usage will be by language-specific wrappers. It provides largely the
+/// same set of functionality as that of the C++ TensorFlow Lite `Interpreter`
+/// API, but is useful for shared libraries where having a stable ABI boundary
+/// is important.
+///
+/// Conventions:
+/// * We use the prefix TfLite for everything in the API.
+/// * size_t is used to represent byte sizes of objects that are
+///   materialized in the address space of the calling process.
+/// * int is used as an index into arrays.
+///
+/// Usage:
+/// <pre><code>
+/// // Create the model and interpreter options.
+/// TfLiteModel* model = TfLiteModelCreateFromFile("/path/to/model.tflite");
+/// TfLiteInterpreterOptions* options = TfLiteInterpreterOptionsCreate();
+/// TfLiteInterpreterOptionsSetNumThreads(options, 2);
+///
+/// // Create the interpreter.
+/// TfLiteInterpreter* interpreter = TfLiteInterpreterCreate(model, options);
+///
+/// // Allocate tensors and populate the input tensor data.
+/// TfLiteInterpreterAllocateTensors(interpreter);
+/// TfLiteTensor* input_tensor =
+///     TfLiteInterpreterGetInputTensor(interpreter, 0);
+/// TfLiteTensorCopyFromBuffer(input_tensor, input.data(),
+///                            input.size() * sizeof(float));
+///
+/// // Execute inference.
+/// TfLiteInterpreterInvoke(interpreter);
+///
+/// // Extract the output tensor data.
+/// const TfLiteTensor* output_tensor =
+//      TfLiteInterpreterGetOutputTensor(interpreter, 0);
+/// TfLiteTensorCopyToBuffer(output_tensor, output.data(),
+///                          output.size() * sizeof(float));
+///
+/// // Dispose of the model and interpreter objects.
+/// TfLiteInterpreterDelete(interpreter);

+# Tensorflow Lite C API library
+
+This is the prebuilt tensorflow lite c library for debian 10. It can be used directly in eKuiper docker image of tags
+x.x.x or x.x.x-slim.
+
+To use in other environment, you need to build the library from source.
+
+## Build from source
+
+Here are the steps to build from source in debian.
+
+1. Install [Python](https://www.tensorflow.org/install/pip#1.-install-the-python-development-environment-on-your-system)
+
+2. Install required python lib: `pip3 install -r requirements.txt`. The requirements are
+   from `tensorflow/tensorflow/tools/pip_package/setup.py` of the corresponding tensorflow version.
+
+3. Install [Bazel](https://docs.bazel.build/versions/4.0.0/install-ubuntu.html)
+
+4. Clone [tensorflow](https://github.com/tensorflow/tensorflow)，switch to `git checkout v2.2.0-rc3 -b mybranch`
+
+5. Build the so files, the outputs are in ./bazel-bin
+
+   ```bash
+   $ cd $tensorflowSrc
+   $ bazel build --config monolithic -c opt //tensorflow/lite:libtensorflowlite.so
+   $ bazel build --config monolithic -c opt //tensorflow/lite/c:libtensorflowlite_c.so
