在 python 上使用 Geopandas 创建交互式地图

Question

我正在尝试使用本指南创建交互式地图：This

我在 anaconda 环境下使用 pycharm，所以我不明白什么时候放我的 .shp 文件。这是示例代码：

import geopandas as gpd
shapefile = 'data/countries_110m/ne_110m_admin_0_countries.shp'
#Read shapefile using Geopandas
gdf = gpd.read_file(shapefile)[['ADMIN', 'ADM0_A3', 'geometry']]

我的目录正确吗？

C:\Users\gpont\PycharmProjects\pythonProject2\data\Map\map1\ne_110m_admin_0_countries.shp

错误：

C:\Users\gpont\anaconda3\envs\pythonProject2\python.exe C:/Users/gpont/PycharmProjects/pythonProject2/main.py
Traceback (most recent call last):
  File "fiona/_shim.pyx", line 83, in fiona._shim.gdal_open_vector

fiona._err.CPLE_OpenFailedError: 'map1 e_110m_admin_0_countries.shp' does not exist in the file system, and is not recognized as a supported dataset name.

During handling of the above exception, another exception occurred:

您的路径中似乎有一个 \n，它被解释为换行符。（注意 'map1 e_110m_admin_0_countries.shp' does not exist 中缺少的 n）

尝试

import os
...
gpd.read_file(os.path.normpath(shapefile))
