Geopand read_file

Question

我在使用 read_file 函数时遇到了一些关于 geopandas 和 fiona 的问题。这是我的回溯：

df = gpd.read_file('/Users/danqing0703/github/Land-Use-Simulation/LBS_Data_Fetching/osm_api/singapore_roads.geojson')

  Reason: Incompatible library version: libgdal.1.dylib requires version 13.0.0 or later, but libjpeg.8.dylib provides version 12.0.0

Answer 1

更新系统 libjpeg 中断了 fiona 的动态链接。有两种处理方法：

我更喜欢：pip uninstall fiona、conda install fiona

如果你想坚持使用 pip：pip uninstall fiona、pip install fiona
