Naveen03 commented 4 years ago

I am running on CPU, while merging confg from yaml file I am getting below error. tried many blogs but was not able to resolve it. I was trying object detection using COCO-Detection/retinanet_R_101_FPN_3x

Here is full error "yaml.constructor.ConstructorError: could not determine a constructor for the tag 'tag:yaml.org,2002:python/object/apply:eval' in "/home/ubuntu/.local/lib/python3.6/site-packages/detectron2/model_zoo/configs/COCO-Detection/../Base-RetinaNet.yaml", line 8, column 12"

and follows another error "cfg = yaml.unsafe_load(f) # pyre-ignore AttributeError: module 'yaml' has no attribute 'unsafe_load"

Please provide me any leads Thank you

Update your yaml parser.
