Run the following code:
python -m venv venv
source venv/bin/activate
python -m pip install --upgrade pip setuptools wheel
python -m pip install nvidia-pyindex
python -m pip install -r requirements.txt
As a quickstart tutorial, we will replicate the experiments at different H values from the paper for the LAgg-A model.

Using MMengine's config file parser, we can write config files directly in Python and use an inheritance config structure to avoid redundant configurations. This can be achieved by specifying config files to inherit from using the
_base_=['my_config.py']
special variable at the top of config files. More information is available at mmengine config docs.
In learned_aggragation, configuration files are logically separated into different directories based on the task to be executed: config/meta_test,config/meta_train, and config/sweeps.
To sweep over the hyperparameters of a model during meta-testing, one can simply specify a sweep configuration using the sweep_config variable.
The checkpoints_to_keep and save_iter config variables control the number of checkpoints that should be kept and the checkpointing multiple, respectively. Default values of checkpoints_to_keep=10 and save_iter=1000 ensure that at most 10 previous checkpoints will be kept and that a checkpoint will be saved every 1000 iterations.
When a checkpoint is logged, it is saved under checkpoints/<meta-train-dir> where <meta-train-dir> is the dynamically assigned meta-train-name. Whenever a new checkpoint is logged, a file called latest is updated with the name of the most recent checkpoint. When resuming from a checkpoint the user simply has to set the --from_checkpoint flag and meta training will automatically resume to the checkpoint specified in the latest file.
