Error message

Unexpected inputs to %s with length at %d

What it means

Error "Unexpected inputs to %s with length at %d" thrown in tensorflow/models.

Thrown at official/projects/roformer/roformer_encoder_block.py:263

    Args:
      inputs: a single tensor or a list of tensors. `input tensor` as the single
        sequence of embeddings. [`input tensor`, `attention mask`] to have the
        additional attention mask. [`query tensor`, `key value tensor`,
        `attention mask`] to have separate input streams for the query, and
        key/value to the multi-head attention.

    Returns:
      An output tensor with the same dimensions as input/query tensor.
