Question

我正在尝试导入pyLDAvis，但它给出了错误ModuleNotFoundError：尽管我同时安装了pyLDAvis和contextvars，但没有名为“ _contextvars”的模块。错误如下

Traceback (most recent call last):

    from _contextvars import Context, ContextVar, Token, copy_context
ModuleNotFoundError: No module named '_contextvars'

我试图删除contextvars.py中的下划线，但没有用。

根据https://github.com/axnsan12/drf-yasg/issues/362#issuecomment-494360308，此问题可能是由于virtualenv未升级到已安装的Python版本所致。

此外，3.7.4已发布并包含与上下文变量有关的更改。也许升级到那个有帮助吗？

无法导入pyLDAvis-ModuleNotFoundError：没有名为“ _contextvars”的模块
