Environment configuration for teams and clusters.
AudioCraftEnvironment picks compute cluster settings (slurm, dora) from the current running environment or declared variable and the loaded team configuration.

The cluster type is identified automatically and base configuration file is read from config/teams.yaml. Use the following environment variables to specify the cluster, team or configuration:
AUDIOCRAFT_CLUSTER (optional): Cluster type to enforce. Useful if the cluster type cannot be inferred automatically. AUDIOCRAFT_CONFIG (optional): Path to yaml config holding the teams configuration.

Cluster configuration are shared across teams to match compute allocation, specify your cluster configuration in the configuration file under a key mapping your team name.
Loads configuration.
Class variables
var DEFAULT_TEAM
Static methods
def apply_dataset_mappers(path: str) ‑> str
-
Applies dataset mapping regex rules as defined in the configuration. If no rules are defined, the path is returned as-is.
def get_cluster() ‑> str
-
Gets the detected cluster. This value can be overridden by the AUDIOCRAFT_CLUSTER env var.
def get_dora_dir() ‑> pathlib.Path
-
Gets the path to the dora directory for the current team and cluster. Value is overridden by the AUDIOCRAFT_DORA_DIR env var.
def get_reference_dir() ‑> pathlib.Path
-
Gets the path to the reference directory for the current team and cluster. Value is overridden by the AUDIOCRAFT_REFERENCE_DIR env var.
def get_slurm_exclude() ‑> str | None
-
Get the list of nodes to exclude for that cluster.
def get_slurm_partitions(partition_types: List[str] | None = None) ‑> str
-
Gets the requested partitions for the current team and cluster as a comma-separated string.
Args
partition_types
:list[str]
, optional- partition types to retrieve. Values must be from ['global', 'team']. If not provided, the global partition is returned.
def get_team() ‑> str
-
Gets the selected team as dictated by the AUDIOCRAFT_TEAM env var. If not defined, defaults to "labs".
def instance()
def reset()
-
Clears the environment and forces a reload on next invocation.
def resolve_reference_path(path: str | pathlib.Path) ‑> pathlib.Path
-
Converts reference placeholder in path with configured reference dir to resolve paths.
Args
path
:str
orPath
- Path to resolve.
Returns
Path
- Resolved path.
