wxee crash in windows WSL linux system

[fanqi203]

I have a code file to use wxee to convert ee image to xarray array data, and it ran successfully on Windows.
But when I ran the same piece of code on Windows Subsystem for Linux (WSL) Ubuntu, it crashes.

Example:

import ee
ee.Initialize()
import wxee
wxee.Initialize()
myregion=ee.Geometry.LineString([[-84, 30], [-70, 45], [-70, 45], [-84, 30]])
cfsr=[]
dem=ee.ImageCollection('NOAA/CFSV2/FOR6H').filter(ee.Filter.date('1996-02-14', '1996-02-19')).select(['u component_of_wind_height_above_ground'])

etc=dem.wx.to_xarray(region=myregion,scale=2000)

print(etc)

The error was

Requesting data: 0%| | 0/20 [00:00<?, ?it/s]malloc(): unsorted double linked list corrupted
Aborted

again, it ran successfully on Windows, but not on WSL.

I don't have a WSL environment to test with, so I'm not able to reproduce the error. It works on my Ubuntu install.

Based on the error message, it's happening at the C level, which might make it tricky to track down and solve. I found one mention of threading as possible cause for this error in Python.

Can you try re-running with dem.wx.to_xarray(region=myregion,scale=2000, num_cores=1)? If communication between threads is the problem, that should solve it by running on a single thread.

setting num_cores=1 solved the problem. Thank you.

Glad that worked!
