ModuleNotFoundError:没有名为“pyproj.crs.crs”的模块；“pyproj.crs”不是包

Question

我正在尝试使用nx.read_gpickle将networkx图形对象作为pickle导入，并收到pyproj.crs包不存在的错误。请注意，我使用的是GOSTnets，这是一个使用networkx、geopandas、osmnx和珍珠树进行网络分析的软件包。

我首先构建了图形，然后使用osmnx.project_graph进行投影，并使用GOSTnets.save进行保存：

G_proj = ox.project_graph(G)

# save Graph as pickle using GOSTnets.save:
gn.save(G_proj,'processed_graph_cleaned_part1_proj','./', pickle = True, edges = False, nodes = False)

# save in networkx terms:
wpath = r"MYPATH"
savename = 'processed_graph_cleaned_part1_proj'
nx.write_gpickle(G, os.path.join(wpath, '%s.pickle' % savename))

然后在另一个笔记本中，我尝试导入图表：

import os, sys, time, importlib

import geopandas as gpd
import pandas as pd
import networkx as nx
import numpy as np
import GOSTnets as gn

# make sure osmium is installed (pip install osmium)
# An internal function called when creating the OSM_to_Network object will import osmium
from shapely.geometry import LineString, Point
import osmnx as ox

# import Graph pickle
G = nx.read_gpickle(r"MYPATH\processed_graph_cleaned_part1_proj.pickle")

在执行此操作时，我收到以下错误：

ModuleNotFoundError: No module named 'pyproj.crs.crs'; 'pyproj.crs' is not a package

我有pyproj版本: 2.4.2.post1，build: py36hc1560cf_1。Networkx版本:2.4。在jupyter和conda一起运行。有谁知道发生了什么吗？如果有重复的问题，很抱歉。

Answer 1

您使用的是过时版本的pyproj。例如，当前版本的OSMnx requires pyproj>=2.6。2.4版没有您尝试使用的CRS模块。请确保根据其installation instructions安装OSMnx。

这与这里回答的问题类似：Cannot import name 'CRS' from 'pyproj' for using the osmnx library
