tensorflow培训后量化支持的操作列表

我希望按照tensorflow lite的协会压缩/优化我的tensorflow NN模型，我使用的是tensorflow 1.13.1（非GPU）

然而，当我使用convert函数时，我遇到了很多错误消息：

ConverterError: TOCO failed. See console for info.

谷歌搜索了一下，这似乎是因为TFLite并不支持所有的tensorflow操作。我的模型具有定制的操作，如注意力、biLSTM等

我如何知道支持哪些NN体系结构？对于我收到的错误，我如何知道问题的根源在哪里？e、 g

Unsupported data type in placeholder op: 20

这20指的是什么？

问题的根源在于ConvertDataType（）函数

不支持的数据类型20为

：

DT_资源=20
