所有, 当尝试按照本页https://www.twilio.com/en-us/blog/geospatial-analysis-python-geojson-geopandas-html中所述导入 states.geojson 文件时,出现以下错误。我认为这个文件是 geopands 的预安装文件之一。
我使用的是geopandas版本0.14.4
import geopandas as gpd
states = gpd.read_file('states.geojson')
这是错误
Traceback (most recent call last):

File fiona/_err.pyx:375 in fiona._err.StackChecker.exc_wrap_pointer
CPLE_OpenFailedError: states.geojson: No such file or directory
The above exception was the direct cause of the following exception:

谢谢
geopandas 的 read_file 方法需要一个文件地址作为输入,如文档中所示 https://geopandas.org/en/stable/docs/reference/api/geopandas.read_file.html
import geopandas as gpd
gpd.read_file("./directory/fileName.json")
您正在寻找的geojson似乎是美国各州的geojson文件。您可以在这里找到它https://github.com/PublicaMundi/MappingAPI/blob/master/data/geojson/us-states.json?short_path=1c1ebe5
下载文件,然后使用该函数读取它并将其存储为地理数据框
