Pretrained models and data

Download our pretrained AttentiveNAS models and a (sub-network, FLOPs) lookup table from Google Drive and put them under folder ./attentive_nas_data

Evaluation

To evaluate our pre-trained AttentiveNAS models, from AttentiveNAS-A0 to A6, on ImageNet val with a single GPU, run:

python test_attentive_nas.py --config-file ./configs/eval_attentive_nas_models.yml --model a[0-6]

Expected results:

Name MFLOPs Top-1 (%)
AttentiveNAS-A0 203 77.3
AttentiveNAS-A1 279 78.4
AttentiveNAS-A2 317 78.8
AttentiveNAS-A3 357 79.1
AttentiveNAS-A4 444 79.8
AttentiveNAS-A5 491 80.1
AttentiveNAS-A6 709 80.7

Training

To train our AttentiveNAS models from scratch, run

python train_supernet.py --config-file configs/train_attentive_nas_models.yml --machine-rank ${machine_rank} --num-machines ${num_machines} --dist-url ${dist_url}

We adopt SGD training on 64 GPUs. The mini-batch size is 32 per GPU; all training hyper-parameters are specified in train_attentive_nas_models.yml.
