Read manifest inside _infer_with_profiler method

[pedrogengo]

🚀 The feature

Add a line to read the manifest file inside the method _infer_with_profiler if self.manifest is None (this can happen in cases the user overwrites the initialize method).

If you think this makes sense, Im more than happy to contribute with it :)

Motivation, pitch

I'm working in some projects where we are overwriting the initialize method from base handler and we weren't creating the self.manifest attribute on it. When I tried to run the torch profiler, the request broke because self.manifest was None. IMO, as this attribute is used for other methods we should guarantee that we will have that or if the attribute is None we can read the file inside the _infer_with_profiler method.

This issue will happen to some examples too, like this one.

Alternatives

• If self.manifest is None, read the file inside _infer_with_profiler;
• Update documentation to be explicit that you need to have the self.manifest defined in your initialize method.

I decided to don't change anything in the _infer_with_profiler, but delegate the manifest checking to handle, as it is the method that call the _infer_with_profiler. Let me know what you think :)
