 - Within the package root directory, make sure `__init__.py` is present
 - Create a ` method.py` and make a `Method` class that inherits from `from semb.methods import BaseMethod` and implement the required methods. See `semb/methods/node2vec/method.py` for more details.
   - Please make sure that your implemented method accepts `networkx.classes.graph.Graph` as input.
-  - Please make sure that when `train()` is called, the `self.embeddings` should be a Python built-in `dict()` with key as `<Node_id (int)>` and value(embedding) as `<List(float)>`.

 - Install the package via `setup.py` or pip.
 - Now the method is load-able by the main client program that uses `semb`!
 
 ### Note
 For both `dataset` and `method` extensions, make sure the `get_id()` to be overridden and returns the same id as your chosen id in your package name.
