onefx 0.0.3

A toolkit for developers to simplify the transformation of nn.Module instances.

one-fx

A toolkit for developers to simplify the transformation of nn.Module instances. It is modified from Pytorch.fx.

install

pip install onefx

Oneflow has now add one-fx as default dependency. You can also install oneflow and use it as oneflow.fx.

usage

The following code shows the basic usage. For more examples, please refer to https://github.com/Oneflow-Inc/one-fx/tree/main/onefx/exmaples.

import oneflow
import onefx as fx

class MyModule(oneflow.nn.Module):
    def __init__(self, do_activation : bool = False):
        super().__init__()
        self.do_activation = do_activation
        self.linear = oneflow.nn.Linear(512, 512)

    def forward(self, x):
        x = self.linear(x)
        x = oneflow.relu(x)
        y = oneflow.ones([2, 3])

        if self.do_activation:
            x = oneflow.relu(x)
        return y

without_activation = MyModule(do_activation=False)
with_activation = MyModule(do_activation=True)
