input must be contiguous when autograd

[Sutongtong233]

When I finetune DualStyleGAN, when d_r1_loss(real_pred, real_img), it call 'upfirdn2d.py', and RunError:

File "/home/tongtong/python_project/DualStyleGAN/model/stylegan/op/upfirdn2d.py", line 143, in backward ctx.out_size, File "/home/tongtong/python_project/DualStyleGAN/model/stylegan/op/upfirdn2d.py", line 42, in forward g_pad_y1, RuntimeError: input must be contiguous

I have tried to add .contiguous() after the input, but it doesn't work. What should I do? Thanks in advance.

I think you can follow the code in fused_act.py to modify the code of upfirdn2d.py https://github.com/williamyang1991/DualStyleGAN/blob/fcc547c7728baffb8ddd0ce21fa0d7252d761786/model/stylegan/op/fused_act.py#L29-L31
