ImportError with matchor and combine_association while running the demo

[guist]

Hi,

I am working under Windows Subsytem for Linux (Ubuntu 18.04. LTS). As required, I have installed LISA and pysobatools, and downloaded the model from Google Drive.

I am trying to run demo.py on the image web-shadow0573.jpg but I get the following ImportError:

Traceback (most recent call last):
  File "demo.py", line 16, in <module>
    from predictor import VisualizationDemo

    from detectron2.modeling.postprocessing import detector_postprocess, matchor, combine_association
ImportError: cannot import name 'matchor' from 'detectron2.modeling.postprocessing' (/home/guillaume/miniconda3/envs/detectron2/lib/python3.7/site-packages/detectron2/modeling/postprocessing.py)

I checked the LISA_meta_arch.py and indeed matchor and combine_association are missing.

Any idea how to solve this issue? Thanks!

Please follow the installation guide in the README and reinstall the detectron2.

I re-installed detectron2 but I am still getting the same error.

Could the problem come from the fact that I am working with a CPU (I do not have a GPU)?

Hi, I encounter the same error as you posted here and in detectron2 repo

I finally solve it under pytorch=1.9.0, cuda=10.2. I think it does not matter with CPU/GPU version.

The official detectron2 is in fact incompatible with InstanceShadowDetection(ISD). Unfortunately, The package that ISD requires torch=1.3.0 cuda=10.0 is somehow hard to obtain. If using new version of pytorch and cuda, directly compiling with python setup.py install would raise error:
