尝试读取 GeoJson 文件，但收到此错误消息 CPLE_OpenFailedError

Question

我正在尝试读取 GeoJson 文件：acs2022_5yr_B01003_15000US060371198021.geojson

我下载了以下库：

读取和可视化空间数据

将 geopandas 导入为 gpd

提供底图

上下文导入为 ctx

为你的图形（图）赋予更多力量

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？

Answer 1

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:
No such file or directory

请注意，您使用的是相对路径，因为它不以 / 开头。因此，当您运行该文件时，将从“当前目录”开始搜索该文件。最好使其成为绝对路径。
