Learning rate of null-text inversion

[UdonDa]

HI, @amirhertz !

Thank you for sharing your cool work! I have a question about the learning rate of your null-text inversion. According to a notebook, the learning rate is set blow. However, in your paper, the learning rate is set to 0.01.

optimizer = Adam([uncond_embeddings], lr=1e-2 * (1. - i / 100.))

where $i$ represents an index of a for-loop for i in range(NUM_DDIM_STEPS):. If we set NUM_DDIM_STEPS over 101, the learning rate gets negative.

My question is that can we modify lr=1e-2 instead of 1e-2 * (1. - i / 100.)?
