【问题描述】：
我为命名实体识别创建了一个 spacy 转换器模型。上次我训练到它达到 90% 的准确率，我还有一个 model-best 目录，我可以从中加载我训练过的模型进行预测。但现在我有更多的数据样本，我希望继续训练这个 spacy 转换器。我看到我们可以通过更改 config.cfg 来做到这一点，但对“要更改什么？”一无所知
这是我运行python -m spacy init fill-config ./base_config.cfg ./config.cfg后的config.cfg：

如您所见，[initialize] 下有一个“向量”参数，所以我尝试从“模型最佳”中提供向量，如下所示：
但它给了我这个错误
OSError: [E884] The pipeline could not be initialized because the vectors could not be found at './model-best/ner'. If your pipeline was already initialized/trained before, call 'resume_training' instead of 'initialize', or initialize only the components that are new.
对于那些想知道我走错路的人。不，该目录存在。可以看到目录结构，
所以，请指导我如何成功地从以前的重量恢复训练。
谢谢！
