摘要：
改后：#加一个.bool()idxs=torch.Tensor.byte().bool()idxs[:]=1idxs[idxs_0=int]=0delta_p_gt=delta_p_gt[idxs]idxs_0_bias=idxs_0[idxs]idxs_end_bis=idxs_end[idxs]
内部实则是bool。
原：
idxs = torch.Tensor(idxs_0.shape[0]).byte()
idxs[:] = 1
idxs[idxs_0 < 0] = 0
idxs[idxs_end >= int(N / args.gps_step)] = 0
delta_p_gt = delta_p_gt[idxs]
idxs_0_bias = idxs_0[idxs]
idxs_end_bis = idxs_end[idxs]
可以看出，实则idxs内部为bool性质。
改后：
# 加一个.bool()
idxs = torch.Tensor(idxs_0.shape[0]).byte().bool()
idxs[:] = 1
idxs[idxs_0 < 0] = 0
idxs[idxs_end >= int(N / args.gps_step)] = 0
delta_p_gt = delta_p_gt[idxs]
idxs_0_bias = idxs_0[idxs]
idxs_end_bis = idxs_end[idxs]
