yaml.scanner.ScannerError: mapping values are not allowed here #35

Open nsage-creatively opened 3 years ago

Trying to run Detectron's inference demo with the PubLayNet models and .yaml configs.

My exact command is:

python demo.py --config-file ../models/e2e_faster_rcnn_X-101-64x4d-FPN_1x.yaml \ --input ../images/sample_image.png \ --opts MODEL.WEIGHTS ../dir2/models/Faster-RCNN.pkl

The full traceback is this:

[04/08 20:23:44 detectron2]: Arguments: Namespace(config_file='../models/e2e_faster_rcnn_X-101-64x4d-FPN_1x.yaml', webcam=False, video_input=None, input=['../images/Page 0.png'], output=None, confidence_threshold=0.5, opts=['MODEL.WEIGHTS', '../models/Faster-RCNN.pkl'])

My brief bits of research didn't turn up much more than this syntactical mistake.

I did a brief search through the .yaml to see if this was occurring, but I didn't see anything. Maybe I missed something, or my prompt is somehow wrong. Let's discuss.

I'm using Python 3.9.2 and detectron2 v0.4.
