Adding graph in Pool processes

[erwinschrodinger1]

While using the pool function mostly I get lost not knowing where it has reached. I get confused weather the process is still operating or not. So, adding simple graphs in every pool process and logging could help in finding the step that we are in.

Example:

Here I have implemented progress bar using tqdm.




If someone can guide me this can be a good new feature (Ready for open source contributions)
