What is partial saving and loading High level API in dynet explain

Recipe Objective - What is partial saving and loading (High-level API) in dynet explain?

We will use "dy.save(basename, lst)" for saving and "dy.load(basename, param_collection)" methods for loading the model.

dy.save() method takes a base filename and a list of objects, and saves them to file.

dy.load() takes a base filename as input and a parameter collection (model) as a 2nd input and returns a list of objects.

import dynet as dy
pc = dy.ParameterCollection()
par1 = pc.add_parameters((100,50))
par2 = pc.add_lookup_parameters((1000,50))
builder_a = dy.LSTMBuilder(3, 60, 60, pc)
builder_b = dy.LSTMBuilder(3, 110, 110, pc)

dy.save("/tmp/model", [par2, builder_b, par1])

# this will create two files, "/tmp/model.data" and "/tmp/model.meta"

# then, when loading:

pc2 = dy.ParameterCollection()
par2, builder2, par2 = dy.load("/tmp/model", pc2)
