AttributeError: 'NoneType' 对象在导入 ktrain 时没有属性 'thread'

问题描述

我正在尝试使用 ktrain 进行主题建模。

它给了我一个奇怪的错误：

AttributeError: 'nonetype' object has no attribute 'thread'

看起来是个常见问题，但仍然无法解决。

我试过了：

!pip install ktrain 和 !pip install ktrain --upgrade 在 Jupyter 中

conda install -c conda-forge cchardet 作为 recommended here 和 here

pip install ktrain 在命令行中
