根因分析

对不规则张量应用了需要稠密张量的操作，必须先将不规则张量转换为稀疏或稠密表示。

English

An operation that requires dense tensors was applied to a ragged tensor, which must be converted to a sparse or dense representation first.

解决方案

  1. Convert the ragged tensor to a dense tensor with explicit padding before the unsupported operation.
  2. Use tf.RaggedTensor.from_tensor to create a ragged tensor and then apply row splitting for compatible ops.

无效尝试

常见但无效的做法:

  1. 90% 失败

    Using tf.sparse.to_dense on a ragged tensor directly fails because ragged tensors are not sparse.

  2. 40% 失败

    Padding the ragged tensor manually with ragged_tensor.to_tensor() may cause memory blowup for large sequences.
