AttributeError: объект 'NoneType' не имеет атрибута 'thread' при импорте ktrain

Question

Я пытаюсь моделировать темы, используя ktrain.

Это дает мне странную ошибку:

      AttributeError                            Traceback (most recent call last)

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

Выглядит как обычная проблема, но все еще не может ее исправить.

Я старался:

!pip install ktrain и !pip install ktrain --upgrade в Jupyter

conda install -c conda-forge cchardetкак рекомендовано здесь и здесь

pip install ktrain в командной строке
