这个错误是由于传递给`folium.PolyLine()`函数的`locations`参数类型不正确导致的。根据错误信息，`locations`应该是一个包含坐标对的列表或元组。

请确保`loc1`和`loc2`是以正确的格式传递给`folium.PolyLine()`函数。你可以使用`[loc1, loc2]`将它们放入一个列表中，如下所示：

folium.PolyLine([[loc1, loc2]], color='blue', weight=2.5, opacity=1).add_to(m)

这个报错提示是无法从markupsafe模块中导入soft_unicode函数。这可能是由于markupsafe模块的版本问题导致的。

您可以尝试使用以下命令更新markupsafe模块：

pip install --upgrade markupsafe

如果更新markupsafe模块无法解决问题，您可以尝试重新安装jupyter notebook：

pip uninstall jupyter notebook
pip install jupyter notebook

如果问题仍未解决，请尝试卸载并重新安装Anaconda，确保使用最新版本的Anaconda。

这个问题通常发生在更新了 anaconda 或者 jupyter notebook 后出现，可能是因为 jinja2 与 markupsafe 版本不兼容所致。你可以尝试升级 markupsafe，或者降级 jinja2 版本，具体步骤如下：

1. 在命令行中输入以下命令更新 markupsafe：`pip install --upgrade markupsafe`

2. 如果更新 markupsafe 无法解决问题，你可以尝试降级 jinja2 版本，命令如下：`pip install jinja2==2.10.1`

如果以上两种方法均不能解决问题，你可以尝试重新安装 anaconda 或 jupyter notebook。
