在Python中运行OSMNX时，如何解决英特尔MK致命错误？

Question

我在Windows10上运行Python3.6.1和Anaconda 4.4.0 (64位)。我正在尝试运行OSMNX示例代码(seen here)。

我的代码从成功导入包开始：

import requests
import matplotlib.cm as cm
import matplotlib.colors as colors
import pandas as pd
import numpy as np
from datetime import datetime
from dateutil.parser import parse
import geopandas
import osmnx 

当我运行以下代码时，我没有发现任何错误：

osmnx.save_gdf_shapefile(city)
city = osmnx.project_gdf(city)
fig, ax = osmnx.plot_shape(city, figsize=(3,3))

运行以下命令时，我发现了一个错误：

G = osmnx.graph_from_point((37.79, -122.41), distance=1, network_type='all')

这是我得到的错误：

如何解决此错误？提前感谢！

您是如何安装OSMnx的？如果你按照它的install instructions把它安装在一个conda环境中，你应该不会遇到这种丢失dll/系统路径的问题。要解决这个问题，最好的办法就是根据文档进行安装。
