根据你提供的路径，C:\\Users\\jiang\\AppData\\Roaming\\JetBrains\\PyCharmCE2023.3\\scratches\\change_In_pl' does not exist. 这个错误提示表明指定的文件或文件夹不存在。可能的原因是路径中的某个部分拼写错误或者文件/文件夹被删除或移动了。

请确保路径中的每个部分都正确，并且检查文件/文件夹是否存在。如果路径中有任何拼写错误，请修正它。如果文件/文件夹确实不存在，你可能需要重新创建或者找到正确的路径。

抱歉，但你不能在Python控制台中直接执行 `pip install` 命令。这个命令应该在命令行中执行。你可以尝试在命令提示符（Windows）或终端（Mac/Linux）中执行 `pip install numpy`。确保你已经退出Python控制台，然后在命令行中运行该命令。这样就可以安装NumPy库了。

看起来你在代码中遇到了一个错误。错误信息显示 `NameError: name 'pd' is not defined`，这意味着你尝试使用了一个未定义的变量 `pd`。

通常情况下，当你在Python中使用 `pd` 时，它是指代了Pandas库。请确保你已经正确导入了Pandas库。在你的代码中添加以下行来导入Pandas库：

import pandas as pd

这样就可以解决该错误并成功读取CSV文件了。如果你还遇到其他问题，请随时告诉我。
