Ubuntu22.04下用Flair做情感分析遇Torch循环导入AttributeError

在Ubuntu 22.04系统上使用Python Flair运行文件情感分析代码时，触发Torch相关的AttributeError，错误信息如下：
AttributeError: partially initialized module 'torch' has no attribute 'autograd' (most likely due to a circular import)

完整回溯信息：

Traceback (most recent call last):
  File "/home/ayush/myproj/vaahan/scrape/sentimentF.py", line 9, in <module>
    from flair.models import TextClassifier

    class CheckpointFunction(torch.autograd.Function):
AttributeError: partially initialized module 'torch' has no attribute 'autograd' (most likely due to a circular import)

使用的代码：

from flair.models import TextClassifier
from flair.data import Sentence
sia = TextClassifier.load('en-sentiment')

def getSentiment3():
    with open("/home/ayush/myproj/vaahan/scrape/scrapeListFile.txt","r") as f:
        content = f.read()  
        flair_analysis = Sentence(content)
        sia.predict(flair_analysis)
        score = flair_analysis.labels[0]

        return score

print(getSentiment3())

• 检查命名冲突：确认你的脚本文件名不是torch.py、transformers.py或flair.py——这类名字会覆盖官方库文件，导致导入时出现循环依赖。如果有，立即重命名脚本。
• 重装损坏的依赖：卸载现有Torch、Transformers和Flair，重新安装兼容版本：

  pip uninstall -y torch transformers flair
  pip install torch==2.0.1 transformers==4.30.2 flair==0.12.2
  

• 使用虚拟环境隔离依赖：避免全局环境依赖混乱，创建并激活独立虚拟环境后再安装依赖：

  python3 -m venv flair_env
  source flair_env/bin/activate
  pip install torch transformers flair
  

• 清理缓存文件：删除项目目录下的__pycache__文件夹，避免缓存的旧代码干扰导入流程。
