First create conda env with python version >= 3.6, this repo has been completely tested on python 3.9.
conda install pytorch==1.13.1 torchvision==0.14.1 torchaudio==0.13.1 pytorch-cuda=11.6 -c pytorch -c nvidia
Install torch, torchvision, cudatoolkit.
Tested on:
pytorch==1.13.1 (py3.9_cuda11.6_cudnn8.3.2_0)
python==3.9.16
cuda 11.6
torchvision==0.14.1 (py39_cu116)
torchaudio==0.13.1 (py39_cu116)
this repo is perfectly compatible with current mainstream zc testing framework, including zennas, naslib, nb201 related repos, nb101, nb1shot1, blox, etc.
If you still cannot use this repo, try to contact me, or try to setup some mainstream nas testing benchmarks, then most problems would be solved.
Finally, if all the previous basic enviroment requirements are met, then try this lib with just one single command.
pip install -e .
# running this command under the root directory where the setup.py locates in.
check installation success.
cd tests/
python test_zc.py

# do not use `bash`, use `source` instead
tenas, add net instance deep copy to avoid weight changes.tenas, now using new torch api to calc eigenvalue.tcet, add net instance deep copy to avoid weight changes, add manually designed tcet copy process, remove bn in synflow, add bn in snip.tcet metric, which calculates TCET score.
Add snr metrics, which calculates SNR family scores.zico metric, which calculates ZICO score.nwot_relu for wrong for/backward fn register,zen for missed necessary attribute check, add test sample for zen metric,zen for return value have not .item() attribute,tenas metric, which calculates TE-NAS score. (tenas, ntk, lrn)zen metric, which calculates ZenNAS score.naswot implements based on RELU, can be calculated using metirc nwot_relu, also fix potential oom bug, and more reliable GPU memory cache removal code snippets.naswot, lnwot into matsif you encouther this error:

please check your lib installation, we need gpu support for torch.half(), please check your cuda version and pytorch version, and reinstall pytorch with cuda support. It seem current cpu version of pytorch does not support torch.half(), even if we are using float32 not float16.
