Module detect 

libtorch installation detection and .arch metadata parsing.

Structs

LibtorchInfo

Metadata about an installed libtorch variant (from .arch file).

Functions

arch_compatible

Check whether a GPU’s compute capability is covered by the libtorch variant’s compiled architectures (from the .arch file).

is_valid_variant

Check whether a libtorch variant directory looks valid (has lib/).

list_variants

List all installed libtorch variants under <root>/libtorch/.

read_active

Read the active libtorch variant from <root>/libtorch/.active and parse its .arch metadata.

read_active_from

Read any .active* pointer file and resolve its content (a relative path like precompiled/cu128 or builds/sm61-sm120) against libtorch_root to produce a LibtorchInfo.

set_active

Set the active libtorch variant by writing <root>/libtorch/.active.
