Python 如何脱机使用ktrain for NER？

我已经按照这个笔记本训练了我的英语模型（）。我能够保存我的预训练模型并毫无问题地运行它

但是，我需要再次运行它，但脱机运行，它不工作，我知道我需要下载文件并执行类似于此处所做的操作

但是，我无法理解我需要在哪里更改ktrain的设置

我运行以下命令：

ktrain.load_predictor('Functions/my_english_nermodel')

这就是我得到的错误：

  File "Z:\Functions\NER.py", line 155, in load_bert
    reloaded_predictor= ktrain.load_predictor('Z:/Functions/my_english_nermodel')

我找到了一个解决方案，当ktrain通过internet连接运行时，它会创建一个文件夹： ''' C:\Users\lemolina.cache\torch\transformers ''' 我需要在无法访问互联网的机器上复制相同的文件夹

更一般地说，基于预训练的模型下载到

/.cache/torch/transformers

。例如，在Linux上，这将是

/home/.cache/torch/transformers

如上面的回答所示，要在没有internet访问的机器上重新加载ktrain

预测器

（对于使用

transformers

库中的模型的

ktrain

模型），您需要将该文件夹中的模型文件复制到新机器上的相同位置
