any demo script?

[Kenneth-X]

Is there any demo script to inference one single image and visualize? like https://github.com/open-mmlab/mmdetection/blob/master/demo/image_demo.py

There is a demo folder contributed in https://github.com/amazon-research/bigdetection/tree/main/demo

i followed the install instruction ,which is :

# Install Pytorch
conda install pytorch==1.8.0 torchvision==0.9.0 cudatoolkit=10.2 -c pytorch

# Install mmcv
pip install mmcv-full==1.3.9 -f https://download.openmmlab.com/mmcv/dist/cu102/torch1.8.0/index.html

# Clone and install
git clone https://github.com/amazon-research/bigdetection.git
cd bigdetection
pip install -r requirements/build.txt
pip install -v -e .

but got the error:

Traceback (most recent call last):
  File "demo/image_demo.py", line 51, in <module>
    main(args)
  File "demo/image_demo.py", line 26, in main

@cailk @JY-Qiao Given the demo script is contributed by you, can you help? Thank you.

Any updates? I am having the same issue with "configs/BigDetection/cbnetv2/htc_cbv2_swin_base_giou_4conv1f_adamw_bigdet.py"

Adding "test" to the "data" dictionary in the config file (link) seems working.

Replace lines 130-134 with this: data = dict( samples_per_gpu=samples_per_gpu, train=dict( pipeline=train_pipeline), test=dict( pipeline=test_pipeline) )

Hi, sorry for the late reply! We have not met such an error in our local environment. It is great that adding a test configuration in "data" would solve this problem. Thank you for your helpful advice.
