Hi!

I am trying to run DARTS following instructions from
https://github.com/D-X-Y/AutoDL-Projects/blob/main/docs/ICLR-2019-DARTS.md

As ./scripts-search/algos/DARTS-V2.sh was not present so I used

./scripts-search/NAS-Bench-201-algos/DARTS-V2.sh.

After that, when I run this command

CUDA_VISIBLE_DEVICES=0 bash ./scripts-search/NAS-Bench-201-algos/DARTS-V2.sh cifar10 1 -1

It shows this

script name: ./scripts-search/NAS-Bench-201-algos/DARTS-V2.sh
3 arguments
Traceback (most recent call last):
  File "./exps/NAS-Bench-201-algos/DARTS-V2.py", line 24, in <module>
    from nas_201_api import NASBench201API as API
ModuleNotFoundError: No module named 'nas_201_api'

Can you share where I might be mistaken.

Thanks!

You can install nas_201_api via pip install nas-bench-201
BTW, this command is to run DARTS on the NAS-Bench-201 dataset/benchmark, if you want to do so, you also need to prepare the data of NAS-Bench-201, which is needed to show the results of searched architecture.

Thank you very much. This error resolved after pip install nas-bench-201.

Good to know that! By the way, NAS-Bench-201 was upgraded to NATS-Bench. I would suggest use the new NATS-Bench (https://github.com/D-X-Y/AutoDL-Projects/tree/main/exps/NATS-algos) to run different baselines. The codes are very similar to that in NAS-Bench-201, but optimized better.
