Steps to install this modified SSIS folder

Create date: 2024/03/02. Test server: tesla.

1. Clone this folder

Git clone this GitHub folder.

Command: git clone https://github.com/Spritea/BoxMOTS.git

Note that we need to clone the modified SSIS folder here, where the file adet/layers/csrc/ml_nms/ml_nms.cu is modified compared to the official SSIS project. Because we use pytorch=1.8.1 with cuda=11.1, we have to use the old version adet/layers/csrc/ml_nms/ml_nms.cu file of old version AdelaiDet project.

GitHub issues of SSIS have mentioned this. If we want to directly use the official SSIS project, we have to use pytorch=1.11+, but this pytorch version requires cuda=11.3+, which is not installed in the server tesla. We have installed cuda=11.1 on the server tesla.

2. Create a conda env

Command: conda create -n myenv python=3.8

3. Pip install PyTorch 1.8.1 with cuda 11.1

Command: pip install torch==1.8.1+cu111 torchvision==0.9.1+cu111 torchaudio==0.8.1 -f https://download.pytorch.org/whl/torch_stable.html

We have to use pytorch=1.8.1, because kornia=0.6.7 requires pytorch=1.8.1+, and pytorch=1.8.0 cannot work after try.

If we use pytorch=1.8.0, we need to use kornia=0.5.6. This is mentioned by the updated requirement.txt in the official SSIS project, but I have not tried yet.

Use pip to install pytorch=1.8.1 is because using conda will show solving environment forever.

4. Install Detectron 2 for PyToch 1.8 and cuda 11.1

Command: python -m pip install detectron2 -f https://dl.fbaipublicfiles.com/detectron2/wheels/cu111/torch1.8/index.html

5. Install numpy 1.23.2

Command: pip install numpy==1.23.2

6. Install old version pillow

Command: pip install pillow==9.2.0

The default installed latest pillow version 10.0+ will report error AttributeError: module 'PIL.Image' has no attribute 'LINEAR', and we need to install old version pillow to fix this issue.

7. Install skimage 0.19.3

Command: pip install scikit-image==0.19.3

8. Install kornia 0.6.7

Command: pip install kornia==0.6.7

9. Install pycocotools

Command: pip install pycocotools

10. Install opencv-python

Command: pip install opencv-python

Ths opencv-python package is needed for demo program.

11. Install old version pysobatools

Command: pip install git+https://github.com/stevewongv/InstanceShadowDetection.git@50764eb336f3194db382054fe537956dd8449c01#subdirectory=PythonAPI

If we use the official SSIS project with python=3.8, it will report error:

/usr/lib/python3.8/multiprocessing/resource_tracker.py:216: UserWarning: resource_tracker: There appear to be 1 leaked semaphore objects to clean up at shutdown

We need to install a specific version of pysobatools to fix this. This problem is mentioned in the official SSIS project GitHub issues here.

THe author says using python=3.10 with the latest version SSIS project should work in this issue, but I have not tried yet.

12. Build the downloaded folder

Command: cd SSIS and then python setup.py build develop.
