sorry , when I use the loss function have the above error. Could you please give me some advices?
I change something to fit my model, the following is my code. But we I use the loss function in my train.py, loss.backward() have the above error.

def topological_loss(recon_x):
batch_size = recon_x.size(0)
b01, b0, b1, b2 = 0., 0., 0., 0.
cpx = init_tri_complex_3d(10, 10, 10）
layer = LevelSetLayer(cpx, maxdim=2, sublevel=False)
f01 = TopKBarcodeLengths(dim=0, k=1)
f0 = PartialSumBarcodeLengths(dim=0, skip=1)
f1 = SumBarcodeLengths(dim=1)
f2 = SumBarcodeLengths(dim=2)
for i in range(batch_size):
dgminfo = layer(recon_x.view(batch_size, patch_side, patch_side, patch_side)[i])
b01 += ((1. - f01(dgminfo))).sum()
b0 += (f0(dgminfo)).sum()
b1 += (f1(dgminfo)).sum()
b2 += (f2(dgminfo)).sum()
b01 = b01.div(batch_size)
b0 = b0.div(batch_size)
b1 = b1.div(batch_size)
b2 = b2.div(batch_size)
topo = b01 + b0 + b1 + b2
return topo

Hello, author
I am reproducing your paper currently, and I don't understand how to make the file'pytorch/vae/filename.txt' ? If it's convenient, just let me know. Thanks so much.
