当我想用我的自定义数据集训练这个“ner_ontonotes_bert_mult”模型时，它会显示下面的错误。（我已将我的数据集保存~\.deeppavlov\downloads\ontonotes 在 [deeppavlov 文档][1] 中提到的文件夹中。）

清理数据集后，上述错误消失了，但这是新错误。新错误

任何人都可以解释如何解决它。[1]：http ://docs.deeppavlov.ai/en/master/features/models/ner.html

conll2003_reader数据集阅读器无法解析以下行：

 O

conll2003_reader数据集阅读器期望该行为空或包含标记和标签。在您的情况下，只有标签存在。

因此，我建议从带有标签的空行中清除您的数据。

DeepPavlov文档中的示例文本：

EU B-ORG
rejects O
the O
call O
of O
Germany B-LOC
to O
boycott O
lamb O

Great B-LOC
Britain I-LOC
