state_dict(*args[, destination, prefix, ...])	Return a dictionary containing references to the whole state of the module.
to(*args, **kwargs)	Move and/or cast the parameters and buffers.
to_empty(*, device[, recurse])	Move the parameters and buffers to the specified device without copying storage.
train([mode])	Set the module in training mode.

Attributes

T_destination
call_super_init
dump_patches
training

__init__()

Initialize internal Module state, shared by both nn.Module and ScriptModule.

Return type:

None

decode(input)

Parameters:

input (Tensor)

Return type:

Any

encode(input)

Parameters:

input (Tensor)

Return type:

List[Tensor]

forward(input, **kwargs)

Define the computation performed at every call.

Should be overridden by all subclasses.

Note

Although the recipe for forward pass needs to be defined within this function, one should call the Module instance afterwards instead of this since the former takes care of running the registered hooks while the latter silently ignores them.

Parameters:

input (Tensor)

Return type:

List[Tensor]

loss_function(recons, input, mu, log_var, **kwargs)

Return type:

dict

reparameterize(mu, logvar)

Reparameterization trick to sample from N(mu, var) from N(0,1).

Parameters:

• mu (Tensor) – Mean of the latent Gaussian [B x D]

• logvar (Tensor) – Standard deviation of the latent Gaussian [B x D]

Returns:

Samples from the latent Gaussian [B x D]

Return type:

z

sample(batch_size, current_device, **kwargs)

Parameters:

• batch_size (int)

• current_device (int)

Return type:

Tensor
