+You can enable `layer_wise` to `True` to display the FLOPs for each module. If you are using a different branch for caching, you might need to check and update the `prv_f` shape.

-You can set `layer_wise` to `True` to see the FLOPs for each module.
+To view the FLOPs for each module, you can set the `layer_wise` parameter to `True`. Additionally, if you want to see the FLOPs for the partial model executed during the retrieve steps, you can find the results in the second step with `cache_interval` larger than 2.
