I can't run the launch file

[lalawinter]

I compiled the code, but the program died as soon as I ran the launch file. I downloaded the calibrated test data set, changed the file path and the rows and columns of the checkerboard. Here are my running commands and results:


I hope you can help me analyze the reasons for the failure，Thank you so much！

see: src/update/UpdaterCameraTracking.cpp: : updatePixelBased, line 254: Eigen::Matrix<double, 84, 1> res; 84 = 2 * checkerboard_rows * checkerboard_cols. so you must make sure checkerboard_rows * checkerboard_cols = 42. this is a bug.
