Hi, you can paste the errors here.
I have not tested on ubuntu20.04. You can try on 18.04.
If I am available, I will try to compile it on ubuntu20.04.
For Sophus, I think you can use the latest code.

I finally sloved all the problem, using fmt 7.X and latest Sophus. With opencv 4.0 there should change some lines to adopt. Ceres version is 1.7.x, which 2.0 is not ok.

I think you need to check something：

1. Calibrate your D435i device.
2. Modify the config file according to the calibration result. The default imu in my example config is the one equipped in ridgeback. The imu in D435i also works, but you need to modify the extrinsic between camera and imu in the config file.
