>cd C:\Users\35131>C:\Users\35131\AppData\Roaming\Python\Python39\site-packages\jupyter_contrib_nbextensions 拒绝访问

拒绝访问的错误通常是由于权限问题导致的。在你执行该命令时，系统提示你没有足够的权限来访问该路径。这可能是因为你没有管理员权限或者该路径被设置为私有。

要解决这个问题，你可以尝试以下几种方法：
1. 以管理员身份运行命令提示符：右键点击命令提示符图标，选择“以管理员身份运行”，然后再次执行该命令。
2. 检查文件夹权限：右键点击该文件夹，选择“属性”，然后切换到“安全”选项卡，确保你有足够的权限来访问该文件夹。
3. 使用其他路径：如果你只是想访问Python的安装路径，可以尝试使用其他路径，比如`cd C:\Users\35131\AppData\Roaming\Python\Python39`。

希望以上方法能够帮助你解决问题。

这个错误可能是由于您的pip缓存中存在损坏的包或损坏的元数据导致的。您可以尝试清除pip缓存并重新安装要求的包，方法如下：

1. 清除pip缓存

在命令行中输入以下命令：

C:\Users\高雅婷\AppData\Local\Programs\Python\Python39\python.exe -m pip cache purge

这将清除pip缓存中的所有包和元数据。

2. 重新安装要求的包

在命令行中输入以下命令，以重新安装要求的包：

C:\Users\高雅婷\AppData\Local\Programs\Python\Python39\python.exe -m pip install <包名>

请将`<包名>`替换为您要安装的包的名称。

如果上述步骤无法解决问题，请考虑使用conda环境或升级pip版本。

根据你提供的信息，你已经安装了transformers库的版本4.30.2。这个版本应该是可以使用`pipeline`函数的。

你可以尝试导入`pipeline`并使用它，例如：

from transformers import pipeline

classifier = pipeline("text-classification")
result = classifier("This is a test sentence.")
print(result)
