create spline bundle and nothing happens.

When I try to reproduce it in the docker and the Court-01/04 datasets, I always get to the following point:

But nothing further happens.

I just tested the LI-Calib Court-01 dataset and found that the calibration process works as expected. Here is what I did:

• Downloaded the image and built the container.
• Entered the container and copied the Court-01 dataset from my host machine to the Docker container.
• Modified the corresponding configuration file (fields such as the bag file path). Since these configuration files are relatively old, some fields may need to be adjusted for compatibility. Lastly, make sure to set UseCudaInSolving to false.
• Sourced the setup.bash file located under the devel directory.
• Ran ikalibr-prog.launch and passed the configuration file path as an argument.

Note: I am using Ubuntu 20.04, and the test was conducted on this system with Docker installed.
