Geopandas使用字节或等效物(Python3x)将ShapeFile保存在内存中

Question

想象一下我正在操纵地形框架。然后，我想使用另一个库(例如NetworkX(加载它，但是由于我的文件很大，因此我不想保存和重新加载它。有没有办法将其保存在内存中？我想它看起来像这样：

import geopandas 
from io import BytesIO 
writeBytes = BytesIO()
### load the demo
world = geopandas.read_file(geopandas.datasets.get_path('naturalearth_lowres'))
### do something trivial to the demo
world['geometry'] = world['geometry'].buffer(0.05)
### save to bytes IO so that I can do something else with it without having to save and read a file 
world.to_file(writeBytes)

运行以上的运行会产生一个类型：预期的str，字节或os.pathike对象，而不是_io.bytesio这是完整的追溯：

任何帮助都将不胜感激，谢谢

geopandas.to_file((需要一个文件路径，而不是字节对象。

使用临时文件(或用于形状文件的文件夹(例如：https：//stackoverflow.com/a/70254174/2023941
