Inter-Architecture Knowledge Transfer

iatransfer is a PyTorch package for transferring pretrained weights between models of different architectures instantaneously.

Drastically speed up your training process using two additional lines of code.

Installation

pip install iatransfer

Usage

  • simple
import torch
from iatransfer.toolkit import IAT

transfer = IAT()

# run training on Model1()
model_from: nn.Module = Model1()

train(model_from)

# instantiate new model
model_to: nn.Module = Model2() 

# enjoy high-accuracy initialization
transfer(model_from, model_to)
  • parametrization
from iatransfer.toolkit import IAT


iat = IAT(standardization='blocks', matching='dp', score='autoencoder', transfer='trace')

# ==== or

iat = IAT(matching=('dp', {'param': 'value'}))

# ==== or

from iatransfer.toolkit.matching.dp_matching import DPMatching

iat = IAT(matching=DPMatching())
  • plugins
from iatransfer.toolkit.base_matching import Matching


class CustomMatching(Matching):

    def match(self, from_module, to_module, *args, **kwargs)
        # provide your implementation


# This will instantiate the above CustomMatching in IAT
iat = IAT(matching='custom')
