repeat(n_repeat, mode='init')

Repeats this Sequential multiple times.

This method returns a Sequential object which has original Sequential multiple times repeatedly. The mode argument means how to copy this sequential to repeat.

The functions is supposed to behave the same way as repeat in chainer.

When the mode is set to init, the default value, modules will be copied and reinitialized by calling reset_parameters (or _reset_parameters) method.

To repeat user-defined modules, which have parameters or buffers, with mode=``init`` in this Sequential, you need to implement the reset_parameters or _reset_parameters method to the module to reinitialize parameters and (if necessary) buffers; otherwise the initialization cannot be performed and a warning message will be shown.

Parameters:

• n_repeat (int) – Number of times to repeat.

• mode (str) – It should be either init, copy, or share. init means parameters of each repeated element in the returned Sequential will be re-initialized, so that all elements have different initial parameters. copy means that the parameters will not be re-initialized but object itself will be deep-copied, so that all elements have same initial parameters but can be changed independently. share means all the elements which consist the resulting Sequential object are same object because they are shallow-copied, so that all parameters of elements are shared with each other.

Return type:

ExtendedSequential
