How Habitat measures the execution time associated with the operation’s backward pass?

Hi! Thanks for your perfect job.

It's easy to understand to measure the execution time in the forward pass.
But in the backward pass, how Habitat does? I think it is an undoubtedly different processor, right?

Habitat re-runs each operation individually. You can look at https://github.com/geoffxy/habitat/blob/master/analyzer/habitat/profiling/operation.py#L96-L148 and the other methods used in that file to see how Habitat makes the measurements.
