`returnn.frontend._native`¶

Native code as Python extension module for the RETURNN frontend, including tensor methods and ops.

returnn.frontend._native.get_module(*, verbose: bool = False)[source]¶

Returns:: native Python extension module

returnn.frontend._native.set_enabled(enabled: bool)[source]¶

Enable or disable the native code setup. Overwrites the global setting.

Parameters:: enabled

returnn.frontend._native.is_enabled() → bool[source]¶: If set_enabled() was called, returns that. Otherwise, check env var, global config. Otherwise, default to True.

returnn.frontend._native.is_set_up() → bool[source]¶

Returns:: whether the native code is set up

returnn.frontend._native.setup()[source]¶: Setup the native code.

returnn.frontend._native.setup_torch()[source]¶: Like setup(), but specifically for the PyTorch backend. This assumes that we can import torch, unlike setup().
