*
|

* Metadata is required for models with int32 input tensors because it contains the input process

|

*
|
||||
* Input tensors:
|
||||
* - Three input tensors `kTfLiteInt32` of shape `[batch_size x bert_max_seq_len]`
|
||||
* representing the input ids, mask ids, and segment ids. This input signature requires
|
||||
* a Bert Tokenizer process unit in the model metadata.
|
||||
* - Or one input tensor `kTfLiteInt32` of shape `[batch_size x max_seq_len]` representing
|
||||
* the input ids. This input signature requires a Regex Tokenizer process unit in the
|
||||
* model metadata.
|
||||
* - Or one input tensor (`kTfLiteString`) that is shapeless or has shape `[1]` containing
|
||||
* the input string.
|
||||
*
|
||||
* At least one output tensor (`kTfLiteFloat32`/`kTfLiteUint8`) with shape `[1 x N]` where `N` is
