stereo kitti problem no IMU

## The problem

i have a problem , i am running stereo kitti example , and i used this yaml %YAML:1.0 #-------------------------------------------------------------------------------------------- # Camera Parameters. Adjust them! #-------------------------------------------------------------------------------------------- Camera.type: "PinHole" # Camera calibration and distortion parameters (OpenCV) Camera.fx: 718.856 Camera.fy: 718.856 Camera.cx: 607.1928 Camera.cy: 185.2157 Camera.k1: 0.0 Camera.k2: 0.0 Camera.p1: 0.0 Camera.p2: 0.0 Camera.bFishEye: 0 Camera.width: 1241 Camera.

## The fix

ORB_SLAM3 stereo KITTI example failing to parse the settings YAML: the value "Viewer.ViewpointY: -100" needs a decimal point. Change it to "Viewer.ViewpointY: -100.0". The YAML parser treats the bare integer as the wrong type; the decimal form parses correctly. Commenter-verified.
