错误原因及方法：猜测是numpy版本不一致，进行卸载重装是最简单的方法，pip uninstall numpy ， pip install numpy，然后重启，测试，结果又有错误提示，这次的提示是

RuntimeError: The current Numpy installation ('D:\\Software\\Anaconda3\\envs\\snp\\lib\\site-packages\\numpy\\__init__.py') fails to pass a sanity check due to a bug in the windows runtime. See this issue for more information: [https://tinyurl.com/y3dm3h86](https://tinyurl.com/y3dm3h86)

错误原因及方法：按照提示网址查看是numpy版本自身存在的问题，按照提示的变通方案是安装其他版本的numpy,即卸载后重新安装pip install numpy==1.19.3

再次导入，测试成功！

osmnx导入成功
