File ~/anaconda3/envs/songshuhui/lib/python3.8/site-packages/geopandas/array.py:792, in GeometryArray.to_crs(self, crs, epsg) 723 """Returns a ``GeometryArray`` with all geometries transformed to a new 724 coordinate reference system. 725 (...) 789 790 """ 791 if self.crs is None: --> 792 raise ValueError( 793 "Cannot transform naive geometries.

这个错误是由于`geopandas`库中的`to_crs`方法无法对未设置坐标参考系统（CRS）的几何图形数据进行转换导致的。在处理地理空间数据时，坐标参考系统是非常重要的，因为它可以定义地理坐标的参考基准和投影方式。

要解决这个问题，需要先设置几何图形数据的坐标参考系统，然后再使用`to_crs`方法进行转换。例如：

import geopandas as gpd

# 读取几何图形数据
gdf = gpd.read_file('data.shp')

# 设置坐标参考系统
gdf.crs = {'init': 'epsg:4326'}  # WGS84经纬度坐标系

# 转换坐标参考系统
gdf = gdf.to_crs({'init': 'epsg:3857'})  # Web墨卡托投影坐标系

在这个例子中，使用`{'init': 'epsg:4326'}`设置WGS84经纬度坐标系作为原坐标参考系统，然后使用`{'init': 'epsg:3857'}`设置Web墨卡托投影坐标系作为目标坐标参考系统，使用`to_crs`方法进行转换。

这错误是由于在处理上面的异常时，另一个异常发生了。根据错误信息，看起来是在使用visdom库时出现了连接错误。这个错误是由于无法建立与本地主机（localhost）的连接引起的，具体原因可能是因为没有运行相应的服务或者端口被占用。

要解决这个问题，你可以尝试以下几个步骤：
1. 确保你已经正确安装了visdom库，并且已经启动了相应的服务。你可以通过命令行输入`python -m visdom.server`来启动visdom服务。
2. 检查端口8097是否被其他应用程序占用。你可以使用命令行工具（如netstat）来检查该端口的占用情况，并尝试释放该端口。
3. 确保你的网络环境正常，防火墙没有阻止连接。

如果以上步骤都没有解决问题，建议你查看visdom库的文档或在相关论坛上寻求帮助，以获取更详细的故障排除步骤和解决方案。

To avoid this error in existing code, use `bool` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.bool_` here. The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations 如何修复

这个错误是由于使用了在NumPy 1.20中被废弃的`np.bool`别名所引起的。可以将`np.bool`替换为`bool`来避免这个错误。可以在代码中查找`np.bool`并将其替换为`bool`。如果你确实需要使用NumPy的布尔类型，可以使用`np.bool_`。你可以查看NumPy 1.20的发布说明以获取更多详细信息和指导。
