different setup of input_hint_block compared to paper?

[liren-jin]

Hi, i noticed that the implementation of the tiny work converting control images into feature space is different from the structure menioned in the paper: "In particular, we use a tiny network E(·) of four convolution layers with 4 × 4 kernels and 2 × 2 strides (activated by ReLU, using 16, 32, 64, 128, channels respectively". The corresponding implementation should be here right(correct me if i am wrong):

ControlNet/cldm/cldm.py

Lines 147 to 163 in ed85cd1

	self.input_hint_block = TimestepEmbedSequential(
	conv_nd(dims, hint_channels, 16, 3, padding=1),
	nn.SiLU(),
	conv_nd(dims, 16, 16, 3, padding=1),
	nn.SiLU(),
	conv_nd(dims, 16, 32, 3, padding=1, stride=2),
