I am trying to re-train the [model (solution 4)](https://github.com/SpaceNetChallenge/SpaceNet_SAR_Buildings_Solutions/blob/master/README.md) but when i save the model it saves as zip file. I have pre-trained model files from original author.  
Is there any way to save the file to .pth but in Binary format?

`torch.save` has an undocumented/not guaranteed option `_use_new_zipfile_serialization` that might help.

However, I would venture that it is better to use the new format. What is not working for you with it?

Best regards

Thomas

\_use\_new\_zipfile\_serialization = False  
worked for me. I found it somewhere else.  
Thanks 😊
