I followed the tutorial, when I launched train_velodyne_td3.py, RViz didn't produce any indoor environment, with error like:

[ERROR] [1712917359.424777513, 1.823000000]: Updating ModelState: model [cardboard_box_0] does not exist [ERROR] [1712917359.424956752, 1.823000000]: Updating ModelState: model [cardboard_box_1] does not exist [ERROR] [1712917359.425014172, 1.824000000]: Updating ModelState: model [cardboard_box_2] does not exist [ERROR] [1712917359.425060643, 1.824000000]: Updating ModelState: model [cardboard_box_3] does not exist [ERROR] [1712917438.270502562, 54.587000000]: Updating ModelState: model [cardboard_box_0] does not exist [ERROR] [1712917438.270569909, 54.587000000]: Updating ModelState: model [cardboard_box_1] does not exist [ERROR] [1712917438.270614372, 54.587000000]: Updating ModelState: model [cardboard_box_2] does not exist [ERROR] [1712917438.270777024, 54.587000000]: Updating ModelState: model [cardboard_box_3] does not exist
