It uses transfer learning to reduce\nthe amount of training data required and shorten the training time.\n\nSupported Tasks\n---------------\n\nThe Model Maker library currently supports the following ML tasks. Click the\nlinks below for guides on how to train the model.\n\n| Supported Tasks | Task Utility |\n|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------|\n| Image Classification: [tutorial](./image_classification), [api](https://www.tensorflow.org/lite/api_docs/python/tflite_model_maker/image_classifier) | Classify images into predefined categories. |\n| Object Detection: [tutorial](./object_detection), [api](https://www.tensorflow.org/lite/api_docs/python/tflite_model_maker/object_detector) | Detect objects in real time. |\n| Text Classification: [tutorial](./text_classification), [api](https://www.tensorflow.org/lite/api_docs/python/tflite_model_maker/text_classifier) | Classify text into predefined categories. |\n| BERT Question Answer: [tutorial](./question_answer), [api](https://www.tensorflow.org/lite/api_docs/python/tflite_model_maker/question_answer) | Find the answer in a certain context for a given question with BERT. |\n| Audio Classification: [tutorial](./audio_classification), [api](https://www.tensorflow.org/lite/api_docs/python/tflite_model_maker/audio_classifier) | Classify audio into predefined categories. |\n| Recommendation: [demo](https://github.com/tensorflow/examples/blob/master/tensorflow_examples/lite/model_maker/demo/recommendation_demo.py), [api](https://www.tensorflow.org/lite/api_docs/python/tflite_model_maker/recommendation) | Recommend items based on the context information for on-device scenario. |\n| Searcher: [tutorial](./text_searcher), [api](https://www.tensorflow.org/lite/api_docs/python/tflite_model_maker/searcher) | Search for similar text or image in a database. |\n\nIf your tasks are not supported, please first use\n[TensorFlow](https://www.tensorflow.org/guide) to retrain a TensorFlow model\nwith transfer learning (following guides like\n[images](https://www.tensorflow.org/tutorials/images/transfer_learning),\n[text](https://www.tensorflow.org/official_models/fine_tuning_bert),\n[audio](https://www.tensorflow.org/tutorials/audio/transfer_learning_audio)) or\ntrain it from scratch, and then [convert](../../models/convert) it to TensorFlow\nLite model.\n\nEnd-to-End Example\n------------------\n\nModel Maker allows you to train a TensorFlow Lite model using custom datasets in\njust a few lines of code. For example, here are the steps to train an image\nclassification model. \n\n from tflite_model_maker import image_classifier\n from tflite_model_maker.image_classifier import DataLoader\n\n # Load input data specific to an on-device ML app.\n data = DataLoader.from_folder('flower_photos/')\n train_data, test_data = data.split(0.9)\n\n # Customize the TensorFlow model.\n model = image_classifier.create(train_data)\n\n # Evaluate the model.\n loss, accuracy = model.evaluate(test_data)\n\n # Export to Tensorflow Lite model and label file in `export_dir`.\n model.export(export_dir='/tmp/')\n\nFor more details, see the [image classification guide](./image_classification).\n\nInstallation\n------------\n\nThere are two ways to install Model Maker.\n\n- Install a prebuilt pip package.\n\n pip install tflite-model-maker\n\nIf you want to install nightly version, please follow the command: \n\n pip install tflite-model-maker-nightly\n\n- Clone the source code from GitHub and install.\n\n git clone https://github.com/tensorflow/examples\n cd examples/tensorflow_examples/lite/model_maker/pip_package\n pip install -e .\n\nTensorFlow Lite Model Maker depends on TensorFlow [pip\npackage](https://www.tensorflow.org/install/pip). For GPU drivers, please refer\nto TensorFlow's [GPU guide](https://www.tensorflow.org/install/gpu) or\n[installation guide](https://www.tensorflow.org/install).\n\nPython API Reference\n--------------------\n\nYou can find out Model Maker's public APIs in [API\nreference](https://www.tensorflow.org/lite/api_docs/python/tflite_model_maker)."]]
