Pose_refine reported the following error: Assertion `!std::isnan(residual2)'

[Yurri-hub]

Thanks for your excellent work. When I converted the KITTI360 data into the required format for pose optimization, the problem of "Assertion !std::isnan(residual2)" was reported After I conducted a series of tests, I found that when the number of frames I used was less than or equal to 35, there was no problem with Pose_refine (0.pcd~34.pcd). But as long as the number of frames is greater than 35, the error will be reported.

The reason is that the format of the initial pose is wrong

The reason is that the format of the initial pose is wrong原因是初始姿势的格式不对

what does it mean?
