cnn_wrapper/network.py:590:29: F821 undefined name 'solve_DLT'

1、When doing a format check on the program, I found

cnn_wrapper/network.py:590:29: F821 undefined name 'solve_DLT'

2、 There are three types of deform_type, "a', "h", "u", what do you mean by expressing them?

thanks.

1. 'a', 'h', 'u' means different types of deformable convolution: affine-constrained dcn, homography-constrained dcn, and unconstrained dcn.
2. DLT is used in the homography-constrained. We empirically find that unconstrained dcn performs best overall, which is the default config of current deformable convolution.
