torch.jit.script_if_tracing#
- torch.jit.script_if_tracing(fn)[source]#
Compiles
fnwhen it is first called during tracing.torch.jit.scripthas a non-negligible start up time when it is first called due tolazy-initializations of many compiler builtins. Therefore you should not useit in library code. However, you may want to have parts of your library workin tracing even if they use control flow. In these cases, you should use@torch.jit.script_if_tracingto substitute fortorch.jit.script.- Parameters
fn – A function to compile.
- Returns
If called during tracing, a
ScriptFunctioncreated bytorch.jit.script is returned.Otherwise, the original functionfn is returned.
