Python 3.x python transformers库的ModuleNotFoundError，尽管它在运行调用任务时安装在venv中

标题。我当前正在尝试运行使用转换器的导入模块，但它会引发以下错误：

ModuleNotFoundError: No module named 'transformers'

它在

classify.py

中导入为：

import common.hybrid as hybrid

我可以用

python3 common/hybrid.py

没有任何错误

使用运行调用任务时

invoke process-data

文件tasks.py位于根项目目录中

一旦到达transformers导入，我就会得到

ModuleNotFoundError

请注意，即使在添加

import tensorflow

在transformers导入上方，这是正确导入的，直到

import transformers

pip冻结

请注意，没有循环导入，我尝试过各种版本的transformers（v3-4）

一切都是用

pip3

安装的，

venv

是用

python3 -m venv tf2venv

我尝试过多次删除

venv

并重新安装，但都没有效果。是否缺少导致此ModuleNotFound变压器错误的内容

我的

激活您的环境，然后执行“pip列表--本地”。你看到输出中的变压器了吗？pip list--local仅显示本地环境中已安装的软件包。请确保您的代码正在安装Transformers的环境中运行。谢谢
