We have encountered and issue with torch.compile and the pipeline module. modifying a member of the module duing the run will cause torch compile to restart the analysis and treat the module as dynamic. this happens because the fwd function will modify the micro_offset attribute of the pipeline module. in order to bypass this issue without significantly changing the way the pipeline module works we propose to compile only the layers in the pipeline module instead of the pipeline module itslef. this will bypass the issue, and should still give most of the benefit of torch compiling the pipeline module while avoiding the issue.

Hi @NirSonnenschein, thank you for the great catch! Can you also add a small test case? We want to make sure that this change works for various settings. |

We have encountered and issue with torch.compile and the pipeline module.
modifying a member of the module (micro_offset) during the forward function will cause torch compile to restart the analysis and treat the module as dynamic.
In order to bypass this issue without significantly changing the way the pipeline module works we propose to compile only the layers in the pipeline module instead of the forward function of pipeline module. this will bypass the issue and should still give most of the benefit of torch compiling the pipeline module while avoiding the issue.
