This is because the crf layer expects the labels in a different shape. Normally your labels would be of shape (num_samples, max_length) but the crf layer expects them in the form (num_samples, max_length, 1) .
An easy fix is to reshape your labels as follows:
labels = labels.reshape((labels.shape[0], labels.shape[1], 1))
这篇博客探讨了在使用条件随机场(CRF)层时遇到的标签形状不匹配问题。通常,标签应该为(num_samples, max_length)形状,但CRF层期望的是(num_samples, max_length, 1)形状。解决方案是简单地将标签重塑为后者,例如:labels = labels.reshape((labels.shape[0], labels.shape[1], 1))。文章还提到了在实现CRF过程中可能出现的索引越界错误。
