PyTorchCheckpoint

Minimal reader for the modern PyTorch zipfile checkpoint format (.pt), with no runtime dependencies beyond the .NET framework.

This library:

  • Opens a PyTorch zip checkpoint and parses data.pkl (pickle) to discover tensors/storages.
  • Provides access to storages (data/<key>) as either a Stream or a byte[].

It is intentionally minimal: it does not execute Python, and it only implements the subset of pickle/PyTorch rebuild ops needed to locate tensors and their storages.

Usage

using PyTorchCheckpoint;

using var ckpt = TorchCheckpoint.Open("model.pt");
foreach (var t in ckpt.Tensors)
{
    Console.WriteLine($"{t.Name} {t.Storage.ScalarType} numel={t.Numel}");
    // For large storages prefer OpenStorage(...) and stream access.
    var bytes = ckpt.GetStorageBytes(t.Storage);
}

Notes / limitations

  • Supports the modern zipfile serialization layout (expects data.pkl plus data/<key> entries).
  • Dtype is inferred from *Storage types referenced by data.pkl (e.g. FloatStorage, HalfStorage, BFloat16Storage, ...).
