我在使用 OSMNX 时遇到错误：使用 ox.graph_from_place 时出现操作系统错误

Question

I recently reinstalled OSMNX using pip and now I get a strange OS error I honestly have never seen before and google did not help me as well...

Here is a code excerpt with the error. I tried to restart the environment and also tried another VE to run it but the same error appears. It does actually not seem to be some native bug of OSMNX and seems to go to geopandas or shapely.

And no, I have never encountered anything similar and I am using anaconda, being the superuser (win10) of this machine with all rights.

You did not follow the OSMnx installation instructions so this error is to be expected. Follow the documented instructions and it will resolve.
