Help: There is no ddim discretization method called "'uniform_trailing'"

[shirubei]

Hello, Thanks for your great work and open source. I tried to run on windows 11 ended up with this error. (I convert the run.sh to run.bat so that it can be run on windows) torch vresion: 2.0.0+cu118

Any solution or hint ? Thanks.

Hi I think it should be caused by the mismatching between the syntax of linux .sh and windows .bat script. In run.sh, L55, 'uniform_trailing' (without quotes) should be passed as the argument of timestep_spacing. You may modify it as "uniform_trailing" or just try uniform_trailing. I am not sure about the syntax in Windows.

This solved my problem. Many thanks and happy Chinese New Year !
