我正在尝试读取 GeoJson 文件:acs2022_5yr_B01003_15000US060371198021.geojson
我下载了以下库:
将 geopandas 导入为 gpd
上下文导入为 ctx
将 matplotlib.pyplot 导入为 plt
我将geojson保存在我的文件夹中(参见下面的路径):OneDrive/pscript/Practice_1/data/acs2022_5yr_B01003_15000US060371198021.geojson
然后我输入以下内容:
gdf = gpd.read_file('OneDrive/pscript/Practice_1/data/acs2022_5yr_B01003_15000US060371198021.geojson')
我收到以下消息:这是什么意思?

如错误所述:在您指定的位置找不到该文件:
DriverError: OneDrive/pscript/Practice_1/data/acs2022_5yr_B01003_15000US060371198021.geojson:
