Meaning of output of demo.py

[Prajwal-Gupta]

After running python demo.py ctdet --demo /path/to/image/or/folder/or/video --load_model ../models/ctdet_coco_dla_2x.pth, i am getting an output like

Fix size testing.
training chunk_sizes: [1]
The output will be saved to  /content/drive/MyDrive/CenterNet2/CenterNet/src/lib/../../exp/ctdet/default
heads {'hm': 80, 'wh': 2, 'reg': 2}
Creating model...
loaded /root/CenterNet/models/ctdet_coco_dla_2x.pth, epoch 230
: cannot connect to X server 

What does this mean and what do the terms 'hm', 'wh', and 'reg' mean?

Also how can I display the output as an image as shown in the readme file as I am unable to locate /content/drive/MyDrive/CenterNet2/CenterNet/src/lib/../../exp/ctdet/default in my directory.
Thanks

these are heatmaps and set of coordinate values

@Dipankar1997161 I am getting the same values for different images, does this mean that the model is not compiled properly?
