Gunakan perpustakaan paralelisme SageMaker model v2

Siapkan smp_config.json file yang berisi kamusParameter konfigurasi fitur inti SMP v2. Pastikan Anda mengunggah file JSON ini ke tempat Anda menyimpan skrip pelatihan Anda, atau jalur yang Anda tentukan ke torch.sagemaker.init() modul di Langkah 1. Jika Anda telah meneruskan 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 sesuai dengan jalur yang Anda tentukan pada Langkah 1. Jika Anda telah meneruskan 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 menginstal SMP, SMDDP, CUDA, dan dependensi lainnya.

# Run on compute nodes
SMP_CUDA_VER=<11.8 or 12.1>

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}
