@SKTT1Ryze thanks for using LightGBM!

I see you opened and then immediately closed this....what happened? It would be useful for others arriving at this issue from search engines to understand the cause of that error and how you got past it.

In the windows platform, model file is dos format and only the unix format is understood by LightGBM.

I see, I suspect you ran into the same issue as #5508.

Thanks for that explanation. In the future, if you post here and then close the discussion, please provide an explanation so that other people finding the conversation from search engines can learn from your experience.
