code path is models/action.py, line63-72. line 63 I could konw x.size is nt, c, h, w. After x forward from line 63 to line 72, could get x_shift and thex_shift.size is nt, c,h,w. The x_shift.size is euqal to x.size. why don't make x_shift = x? I want to konw what function of these code.

x_shift is probably refered from STM and TSM.
