Gunakan perpustakaan paralelisme SageMaker model v2

Siapkan smp_config.json file yang berisi kamusSMPParameter konfigurasi fitur inti v2. Pastikan Anda mengunggah JSON file ini ke tempat Anda menyimpan skrip pelatihan Anda, atau jalur yang Anda tentukan ke torch.sagemaker.init() modul di Langkah 1. Jika Anda telah melewati kamus konfigurasi ke torch.sagemaker.init() modul dalam skrip pelatihan di Langkah 1, Anda dapat melewati langkah ini.

// smp_config.json
{
    "hybrid_shard_degree": Integer,
    "sm_activation_offloading": Boolean,
    "activation_loading_horizon": Integer,
    "fsdp_cache_flush_warnings": Boolean,
    "allow_empty_shards": Boolean,
    "tensor_parallel_degree": Integer,
    "expert_parallel_degree": Integer,
    "random_seed": Integer
}

Unggah smp_config.json file ke direktori di sistem file Anda. Jalur direktori harus cocok dengan jalur yang Anda tentukan di Langkah 1. Jika Anda telah melewati kamus konfigurasi ke torch.sagemaker.init() modul dalam skrip pelatihan, Anda dapat melewati langkah ini.

Pada node komputasi cluster Anda, mulai sesi terminal dengan perintah berikut.

sudo su -l ubuntu

Buat lingkungan Conda pada node komputasi. Kode berikut adalah contoh skrip untuk membuat lingkungan Conda dan menginstalSMP,, SMDDPCUDA, dan dependensi lainnya.

# Run on compute nodes

source /fsx/<path_to_miniconda>/miniconda3/bin/activate

export ENV_PATH=/fsx/<path to miniconda>/miniconda3/envs/<ENV_NAME>
conda create -p ${ENV_PATH} python=3.10

conda activate ${ENV_PATH}
