Demo.py not working

[shashank288]

Hi team,

I am trying to set up the codebase in my system and I have installed the necessary requirements as mentioned in the readme section of this repository.

ISSUE 1:-

However, whenever I am trying to run the demo.py file (with webcam operation enabled) from the root folder of the repo. I am getting the following error:-

Command used :- `python tools_d2\demo.py --config-file C:\EDS\Current_tasks\POC\Panoptic_segmentation_GT_generator\Re
po\panoptic-deeplab\configs\panoptic_deeplab_R101_os32_cityscapes.yaml --webcam

Command prompt output :-

`Traceback (most recent call last):
File "C:\EDS\Current_tasks\POC\Panoptic_segmentation_GT_generator\Repo\panoptic-deeplab\tools_d2\demo.py", line 14, in
from d2.predictor import VisualizationDemo

ModuleNotFoundError: No module named 'segmentation'

ISSUE 2:-

When I try to work around the first issue by commenting out the import:- from .backbone import d2_xception_65 in the __init__.py file present in tools_d2/d2, I get the following error:-

Command used :- `python tools_d2\demo.py --config-file C:\EDS\Current_tasks\POC\Panoptic_segmentation_GT_generator\Re

This issue occurs with all the configuration files present in ROOT/configs folder.

Could someone please help me troubleshoot these issues ? Thanks in advance 😀.

Hi. I want to share a simple solution about ISSUE1 with the writer or potential users who encountered this issue.

The reason why ISSUE1 occurs is the segmentation folder(or package) isn't added to the Python path.

You can simply insert a line import _init_paths before importing segmentation module at panoptic-deeplab\tools_d2\d2\backbone.py file.

I hope this simple solution could help you guys. Thanks.
