Specifically, we provide the following:

Computation Graph (CG) data caches for all datasets used in the paper.
Code for generating individually labeled CG samples, as well as training a shared head to generate pseudo-labels.
Predictor code including AIO-P with k-Adapters and label scaling, as well as the baseline GNN.
Code API for generating, loading and visualizing CGs.

Setup

Dependencies

Machine with an NVIDIA GPU and CUDA (>=10.2) support
Python 3.7
System: Ubuntu 20.04.4 LTS
Conda is installed

Installing packages

First create a conda environment

conda create -n aiop python=3.7
conda activate aiop

Install conda packages

$ conda install -c anaconda tensorflow-gpu=1.15.0 cudatoolkit

Install pip packages (can use conda instead, but this worked for us)

$ pip install --trusted-host pytorch.org --trusted-host download.pytorch.org  torch==1.8.1+cu102 torchvision==0.9.1+cu102 torchaudio==0.8.1 -f https://download.pytorch.org/whl/torch_stable.html
$ pip install --trusted-host pytorch-geometric.com torch-scatter==2.0.8 torch-sparse==0.6.11 torch-cluster==1.5.9 torch-spline-conv==1.2.1 -f https://pytorch-geometric.com/whl/torch-1.8.1.html
$ pip install torch_geometric==1.7.2 opencv-python thop
$ pip install git+https://github.com/facebookresearch/detectron2.git git+https://github.com/cocodataset/panopticapi.git

These commands worked for us, but your mileage may vary. We note that for Detectron2 to work properly, torch and torchvision should be compiled with a version of CUDA which is reflected in their respective __version__ fields.

Downloading Datasets

Download Computational Graph (CG) caches:
- Download cache.zip from the shared google drive and place all .pkl files in /cache/.
  - Caches with ind in their name are individually-trained architectures. shared refers to architectures fine-tuned by a shared head.
  - deeplab' or slim' caches refer to model zoos.
  - Caches without either are classifiction CGs.
- Download sample_pbs.zip from the shared google drive for examples of ResNet-18 and EfficientNet-B0.
Download the following datasets:
- LSP
  - Unzip contents to data/HPE/lsp
- LSP Extended
  - Unzip contents to data/HPE/lsp_extended
- MPII
  - Unzip and place the annot and images folders under data/HPE/mpii
- COCO
  - Set up the detectron2 COCO dataset: https://github.com/facebookresearch/detectron2/tree/main/datasets

Setting up the repository

Download and unpack CG_data.zip
Place .pkl files in cache folder
Set the environment variable DETECTRON2_DATASETS to the directory containing the coco datasets:
```
export DETECTRON2_DATASETS=/home/...
```

Experiments

Training individual architectures

The run_train_cgs_on_task.py will train individual architectures to be used as test architectures that represent the ground truth.
Inside the cache folder, this script will output a subfolder with a .txt file that contains the logs and a .pkl file with the trained architectures

Example for Detectron2

python run_train_cgs_on_task.py -family ofa_mbv3 -task detectron2 -tag individual -start_idx 0 -num_archs 10 -skip --num-gpus 2 --config-file tasks/detectron2/COCO_PanSeg_FPN_Adapted_Head.yml

-family is the OFA family to train, select from one of ofa_pn, ofa_mbv3, and ofa_resnet.
-task detectron2 will execute the detectron2 code
-tag can be any string that labels the output folder
-start_idx is the start index of the architectures to train
-num_archs is the number of architectures to train
-skip uses skip connections
--num-gpus 2 uses 2 GPUs. We use Tesla V100 GPUs with 32GB of VRAM each, so depending on your computer resources, you may need to increase number of GPUs to avoid CUDA Out of memory errors

Need graphviz library.
Saves CGs as images which you can then view.
E.g., print pictures for the models we provided .pb files for, then compare to the actual model using Netron.
