Hi Akash, there is no need for a different approach when you save your model. Once you have saved your model, create the model.tar.gz file with the following command: tar zcvf model.tar.gz * ,  just like described in the documentation I linked to earlier.
I looked for example notebooks and found this one: midas_depth_estimation.ipynb · GitHub 1
The markdowns are in Japanese (I think) but the code should be helpful for you to get an idea how to go about it.
Hope that helps.
Cheers
Heiko
