使用TFLiteConverter（Python API）将冻结的图形转换为Coral的tflite

我正在尝试将这种预先培训过的格式转换为tflite格式，以便在Google Coral板上工作；我无法绕过此错误：

检查失败：dim>=1（0对1）

。知道我做错了什么吗？下面是代码（Tensorflow版本：

1.13.1

；Python版本

Python 3.7.3

，平台：

Mac

）：

以下是输出：

感谢您的帮助

我见过使用命令行。

tf.lite.TFLiteConverterAPI支持有限数量的要转换的操作。可能

mobilenetw2

包含不受支持的操作。我坚持要求您遵循以下步骤：

如果需要

MobileNetV2

模型，请在Python文件中创建

tf.keras.applications.MobileNetV2

的实例

您将有一个

tf.keras.models.Model

实例。如果需要，在自定义数据集上训练此模型

现在，使用

tf.lite.TFLiteConverter.from\u keras\u model（）

方法将此模型转换为.tflite

此模型将转换为TFLite，而不会出现任何兼容性问题

您从TensorFlow模型动物园下载了.pb文件。此文件包含TFLite可能不支持的TF ops。因此，我们使用Keras预训练模型，该模型默认包含支持的ops

谢谢Shubham。我是
