Thank you for sharing this work, I encountered such a problem in the process of running, do you know how to solve it?

Hello @Jack47746 ,

I would like to ask you how do you fix this error because I'm trying HITNet but I'm facing with the same error that you posted.

Could you help me?

Thank You.

Hello @Jack47746 @Como93 I have also encountered the same problem. May I ask how you resolved it? Thank you very much for your help.

Hi @DWJ111, hope you are fine and sorry for the late reply! Did you try to build the "slant_window" folder with the repository instructions? Because I had problem there last time that I tried to launch the neural network and I solved it. If you want we can discuss it in separate way in order to solve you problem and know each other.

Best regards

Michele
