einspace: Searching for Neural Architectures from Fundamental Operations

Accepted to NeurIPS 2024

[paper] [project page]

This is the official codebase for einspace, a new expressive search space for neural architecture search.

image

Diverse architectures can be represented in our expressive space as shown above for ConvNets, transformers and MLP-only networks.

Follow the instructions below to set up the environment, data, and then run an example script.

Environment Setup

We provide a sample setting up script as following:

conda create -n einspace python=3.10 -y
source activate einspace
pip install torch==1.13.1+cu117 torchvision==0.14.1+cu117 -f https://download.pytorch.org/whl/torch_stable.html
pip install git+https://github.com/SamsungLabs/zero-cost-nas.git
pip install tqdm scipy einops positional_encodings seaborn sympy h5py librosa
pip install -r requirements.txt
pip install -e .

Data Setup

Please follow the official instructions of UnseenNAS and NASBench360 to setup the dataset, after which you can place the files using the following arrangement.

Running Experiments

python einspace/main.py --config $config --device $GPU

For example, to execute the RE(RN18) experiment on the Language dataset, you can run

python einspace/main.py --config configs/language/re_language.yaml --device cuda:0
