- class trw.arch.darts_cell.MixedLayer(primitives, c, stride)¶
Bases:
torch.nn.Module
Represents a mixture of weighted primitive units
- forward(self, x, weights)¶
- trw.arch.darts_cell.default_cell_output(node_outputs, nb_outputs_to_use=4)¶
- class trw.arch.darts_cell.SpecialParameter¶
Bases:
torch.nn.Parameter
Tag a parameter as special such as DARTS parameter. These should be handled differently depending on the phase: training the DARTS cell parameters or the weight parameters
- trw.arch.darts_cell._identity(x)¶
- class trw.arch.darts_cell.Cell(primitives, cpp, cp, c, is_reduction, is_reduction_prev, internal_nodes=4, cell_merge_output_fn=default_cell_output, weights=None, with_preprocessing=True, genotype=None)¶
Bases:
torch.nn.Module
Base class for all neural network modules.
Your models should also subclass this class.
Modules can also contain other Modules, allowing to nest them in a tree structure. You can assign the submodules as regular attributes:
import torch.nn as nn import torch.nn.functional as F class Model(nn.Module): def __init__(self): super(Model, self).__init__() self.conv1 = nn.Conv2d(1, 20, 5) self.conv2 = nn.Conv2d(20, 20, 5) def forward(self, x): x = F.relu(self.conv1(x)) return F.relu(self.conv2(x))
Submodules assigned in this way will be registered, and will have their parameters converted too when you call
to()
, etc.- Variables
training (bool) – Boolean represents whether this module is in training or evaluation mode.
- _create_weights(self, primitives, weights)¶
Create the weights. Do not store them directly in the model parameters else they will be optimized too!
- forward(self, parents)¶
- get_weights(self)¶
- Returns
The primitive weights for this cell. This is useful if we want to share the weights among multiple cells
- get_genotype(self)¶
- Returns
The genotype of the cell given the current primitive weighting
