使用spaCy构建自定义模型时出错

Question

问题

在官方指令之后，我尝试添加一个额外的训练数据集，并在本地cpu环境中训练一个模型。

但我不会更改base_config.cfg和config.cfg文件的内容。

如何修复这些错误来构建模型并对其进行评估？

错误

我不确定第一个问题是否是一个问题，我也不知道如何填写config.cfg文件。

1. 到目前为止，即使在执行以下过程中的代码之后，config.cfg文件仍然是空的。
2. 执行列车命令时会显示错误消息。

ℹ Using CPU
✘ Error parsing config overrides
paths -> train   not a section value that can be overwritten

代码

$ python3 -m spacy train config.cfg --output ./output --paths.train train.spacy --paths.dev train.spacy

迄今为止的程序

$ python3 -m spacy init fill-config base_config.cfg config.cfg

#former output

base_config.cfg从官方指令上的表单下载

# you can run spacy init fill-config to auto-fill all default settings:

Answer 1

好像你双贴了配置之类的？从错误中您会注意到，它说您有两个[paths]部分。在你的文件的一半时间里，有这样的评论：

# This is an auto-generated partial config. To use it with 'spacy train'

试着从那里删除所有的东西，然后再做一次。
