Question

我正在尝试让此PoseNet ResNet50 model在iPhone XS上的Swift中工作。为此，我需要将其转换为tflite格式。由于我没有找到任何直接的方法来做到这一点；最有前途的解决方案似乎是使用tfjs converter将tfjs模型转换为keras_saved_model，然后使用TensorFlow Lite converter将其转换为tflite。

我很难转换为keras_saved_model。这是我尝试过的方法以及如何重现错误的方法：

下载此模型https://tfhub.dev/tensorflow/tfjs-model/posenet/resnet50/float/1/default/1
打开下载的文件夹，并将model-stride32.json重命名为model.json
移回父文件夹并运行tensorflowjs_wizard
输入模型路径（./posenet_resnet50_float_1_default_1）
您将看到与此类似的错误：

Welcome to TensorFlow.js Converter.
? Please provide the path of model file or the directory that contains model files. 
If you are converting TFHub module please provide the URL.  ./posenet_resnet50_float_1_default_1
