Dynamic path for DS-mobilenet

[NoLookDefense]

Hi. Thanks for your work. I am reading your paper and trying to reimplement, and I feel confused about some details.
You mentioned in your paper that the slimming ratio ρ∈[0.35 : 0.05 : 1.25], which have 18 paths.
However, in your code, there are only 14 paths ρ∈[0.35 : 0.05 : 1] as mentioned in

DS-Net/dyn_slim/models/dyn_slim_net.py

Line 36 in 15cd303

[list(range(736, 1152 + 1, 32)), 2, 3, 2, 'ds', False],

. And also, when conducting gate training, the gate function only has a 4-dimension output, meaning that there is only 4 paths and the slimming ratio is restricted to ρ∈[0.35 : 0.05 : 0.5].

DS-Net/dyn_slim/models/dyn_slim_blocks.py

Line 204 in 15cd303

channel_gate_num=4 if has_gate else 0)

Why the dynamic path for larger network is not used?

Hi, @NoLookDefense
We made some explanations on the implementation of the routing space in the Supplementary Material.

1. For number of paths:

2. For restricted paths:

Please feel free to ask if you have further questions.
