This code is provided as a reference of the code used to run experiments in the paper. Please use https://github.com/negrinho/deep_architect instead if you plan to build on our language, as that is the repo that will be maintained going forward.

To run this code, go to the root directory and run python main.py with the required arguments.

Usage: main.py [-h] [--search-space {genetic,nasnet,nasbench,flat}]
               [--searcher {random,mcts,smbo,evolution}] --data-dir DATA_DIR
               [--tpu-name TPU_NAME] [--use-tpu]
               [--evaluation-dir EVALUATION_DIR] [--num-samples NUM_SAMPLES]

If you are training locally not on a TPU, then you can ignore the next paragraph.

If using a TPU for training, the --tpu-name and --use-tpu parameters are required. Furthermore, the --data-dir and --evaluation-dir arguments must be directories in Google Cloud Storage, and you must have the GOOGLE_APPLICATION_CREDENTIALS environment variable set to the file containing your Google service key (see https://cloud.google.com/docs/authentication/getting-started).

The --search-space argument takes in the name of the search space for the search. The values genetic, nasnet, nasbench, and flat are supported.

The --searcher argument takes in the name of the searcher for the search. The values random, mcts, smbo, and evolution are supported.

The --data-dir argument takes in the name of the directory where CIFAR-10 TFRecords are. Run python datasets/generate_cifar10_tfrecords.py to generate the files. Required argument.

The --evaluation-dir argument takes in the name of the directory where the Tensorflow estimator will produce checkpoint and summary files.

The --num-samples argument takes in how many architectures you want to sample during the search.
