Pruner

A repo for Pruner

• This repo is based on a fork of Tenset.

Installation

1. Build and install this repo following the guide.

2. Version information can refer to here.

3. Register device abstraction on Pruner as abstraction

Using Pruner on Nvidia GPUs

Quick tutorial on using Pruner on NVIDIA A100 refer to tutorial.

On-Line cost model Mode

Steps

1. Search with Pruner (tuning 2,000 trials)

python3 tune_network.py --network resnet_50 --n-trials 2000 --cost-model pam --target "cuda --model=a100" --psa a100_40

2. Search with the MoA-Pruner (tuning 2,000 trials)

python3 tune_network.py --network resnet_50 --n-trials 2000 --cost-model pam-siamese-update --load-model pam_k80_1500.pkl --target "cuda --model=a100" --psa a100_40

3. Search with Ansor (tuning 2,000 trials)

# Using TensetMLP code
python3 tune_network.py --network resnet_50 --n-trials 2000 --cost-model mlp --target "cuda --model=a100"

Off-line cost model Mode

Steps

1. Pretrain or Finetune a model refer to tutorial

2. Search with the Pruner w/ finetuned model (tuning 2,000 trials)

python3 tune_network.py --network resnet_50 --n-trials 2000 --cost-model pam-no-update --load-model pam_finetune.pkl --target "cuda --model=a100" --psa a100_40

3. Search with the TensetMLP (tuning 2,000 trials)

# Using TensetMLP code
python3 tune_network.py --network resnet_50 --n-trials 2000 --cost-model mlp-no-update --load-model mlp_finetune.pkl --target "cuda --model=a100"
