README
**NASLib** is a modular and flexible framework created with the aim of providing a common codebase to the community to facilitate research on **Neural Architecture Search** (NAS). It offers high-level abstractions for designing and reusing search spaces, interfaces to benchmarks and evaluation pipelines, enabling the implementation and extension of state-of-the-art NAS methods with a few lines of code. The modularized nature of NASLib
allows researchers to easily innovate on individual components (e.g., define a new
search space while reusing an optimizer and evaluation pipeline, or propose a new
optimizer with existing search spaces). It is designed to be modular, extensible and easy to use.
NASLib was developed by the [**AutoML Freiburg group**](https://www.automl.org/team/) and with the help of the NAS community, we are constantly adding new _search spaces_, _optimizers_ and _benchmarks_ to the library. Please reach out to [email protected] for any questions or potential collaborations.

# Setup
While installing the repository, creating a new conda environment is recomended. [Install PyTorch GPU/CPU](https://pytorch.org/get-started/locally/) for your setup.
```bash
conda create -n mvenv python=3.7
conda install pytorch torchvision torchaudio cudatoolkit=11.1 -c pytorch -c nvidia
```
Run setup.py file with the following command, which will install all the packages listed in [`requirements.txt`](requirements.txt)
```bash
pip install --upgrade pip setuptools wheel
pip install -e .
```
To validate the setup, you can run tests:
```bash
cd tests
coverage run -m unittest discover -v
```
The test coverage can be seen with `coverage report`.
## Queryable Benchmarks
NASLib allows you to query the following (tabular and surrogate) benchmarks for the performance of any architecture, for a given search space, dataset and task. To set them up, simply download the benchmark data files from the these URLs and place them in `naslib/data`.

For `NAS-Bench-301` and `NAS-Bench-NLP`, additionally, you will have to install the NASBench301 API from [here](https://github.com/crwhite14/nasbench301).
Once set up, you can test if the APIs work as follows:
```
python test_benchmark_apis.py --all --show_error
```
You can also test any one API.
```
python test_benchmark_apis.py --search_space --show_error
```
# Usage
To get started, check out [`demo.py`](examples/demo.py).
```python
search_space = SimpleCellSearchSpace()
optimizer = DARTSOptimizer(**config.search)
optimizer.adapt_search_space(search_space, config.dataset)
trainer = Trainer(optimizer, config)
trainer.search() # Search for an architecture
trainer.evaluate() # Evaluate the best architecture
```
For more examples see [naslib tutorial](examples/naslib_tutorial.ipynb), [intro to search spaces](examples/search_spaces.ipynb) and [intro to predictors](examples/predictors.md).
### Scripts for running multiple experiments on a cluster
The `scripts` folder contains code for generating config files for running experiments across various configurations and seeds. It writes them into the `naslib/configs` folder.
```bash
cd scripts
bash bbo/make_configs_asr.sh
```
It also contains `scheduler.sh` files to automatically read these generated config files and submits a corresponding job to the cluster using SLURM.
