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

Question

我正在尝试使用 nx.read_gpickle 将 networkx 图形对象导入为 pickle，但收到 pyproj.crs 包不存在的错误。请注意，我正在使用 GOSTnets，这是一个使用 networkx、geopandas、osmnx 和 peartree 为网络分析开发的软件包。

我首先构建了图形，然后使用 osmnx.project_graph 投影并使用 GOSTnets.save 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")

这样做时，我收到以下错误：

我有 pyproj 版本：2.4.2.post1，构建：py36hc1560cf_1。 Networkx 版本：2.4。运行 jupyter 中的 conda。有谁知道发生了什么事？如果问题重复，我们深表歉意。

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. Version 2.4 does not have the CRS module you are trying to use. Make sure you install OSMnx according to its installation instructions.

这类似于此处回答的问题：Cannot import name 'CRS' from 'pyproj' for using the osmnx library
