我试图自己解决问题，但我无法解决，我试图以您可以想象的每种格式运行此代码，并且在ArcGIS Pro软件中也一样，我找不到此错误消息在任何其他问题上。从类似的问题来看，似乎有些数据文件可能丢失了？
import geopandas as gpd
import json
import numpy as np
from shapely.geometry import LineString, Point, box
import ast
from pyproj import Proj
paths = road_features.SHAPE.map(lambda x: np.array(ast.literal_eval(x)["paths"][0]))
pathLineStrings = paths.map(LineString)
gdf = gpd.GeoDataFrame(road_features,geometry=pathLineStrings)
#gdf.crs = {'init': 'epsg:3857'}
gdf.crs = {'init': 'epsg:4326'}
gdf = gdf.to_crs({'init': 'epsg:4326'})
我收到此错误
RuntimeError: b'no arguments in initialization list'
我也在arcgis pro中尝试过，我也得到了

问题可能出在Windows平台上Anaconda的pyproj安装中。就像史蒂芬所说，解决方案是在“ datadir.py”（位于... Anaconda3 \ Lib \ site-packages \ pyproj中）中编辑路径。
正确的路径是“ ... / Anaconda3 / Library / share”。确保完整路径完整（可能包含用户名等）。我还需要将\更改为/。 这种变化对我有用。是的，进行此更改后，有必要重新启动Spyder（或您使用的任何设备）。
答案 1 :(得分：1)
使用Geopandas，尝试这样做（应该可以使用）：
gdf = gpd.GeoDataFrame(gdf, geometry=gdf['geometry'])
gdf.crs = {'init' :'epsg:2154'}
gdf = gdf.to_crs({'init' :'epsg:4326'})
您应该重新定义地理数据框， 然后定义初始地理参考 并最终将其转换为好的。 如果有的话，不要忘记删除NaN。
答案 2 :(得分：0)
是否定义了初始crs？
仅当我仅通过epsg命令gdf.to_crs('epsg:4326')时，才遇到相同的问题。
如图所示
my_geoseries.crs = {'init' :'epsg:3857'}
应该是第一步，然后转换为
gdf = gdf.to_crs({'init': 'epsg:4326'})
如果您使用的是ArcGIS，还可以在属性中检查是否定义了初始epsg？
很好，这就是答案

确保这是pyproj错误，而不是geopandas。

如果上述运行时错误相同，则可以确定此错误是由于pyproj引起的。
只需conda删除pyproj并使用pip进行安装即可。
pip安装pyproj
至少这对我有用。

我正在使用Pycharm。 我不得不同时使用史通史的言论和多雷加雷的言论。
import pyproj
pyproj.Proj("+init=epsg:4326")
> RuntimeError: b'no arguments in initialization list'
据石史（Stone Shi）说，以上证明它是一个pyproj err。 所以我用了Pycharm-> Settings并重新安装了pyproj。 然后
import pyproj
pyproj.Proj("+init=epsg:4326")
> RuntimeError: b'no arguments in initialization list'
所以，这是pyproj错误，但是 Pycharm->重新安装pyproj的设置对我没有帮助。
然后我编辑了C：\ Anaconda3 \ Lib \ site-packages \ pyproj \ datadir.py 来自：
pyproj_datadir="C:/Anaconda3\share\proj"
多雷加里的：
pyproj_datadir="C:\Anaconda3\Library\share"
然后再次测试：
import pyproj
pyproj.Proj("+init=epsg:4326")
>Process finished with exit code 0
没有运行时错误！
然后在我的
上进行测试wgs84 = data.to_crs({'init': 'epsg:4269'})
>Process finished with exit code 0

我遇到了同样的错误。我使用的是Python 3.6.3版和Geopandas 0.4.0版。通过使用以下而不是df = df.to_crs({'init': 'epsg:4326'})来解决此问题：
df = df.to_crs(epsg=4326)
答案 6 :(得分：0)
对于我升级pyproj和geopandas而言，已解决此问题：
pip install pyproj --upgrade
pip install geopandas --upgrade
答案 7 :(得分：0)
你可以直接使用 pip 强制重新安装 pyproj
pip install --upgrade --force-reinstall pyproj
而不是卸载并重新安装，这也会卸载所有依赖库
