docstring: Returns a :py:class:`ParameterDict` containing this :py:class:`Block` and all of its
          children's Parameters(default), also can returns the select :py:class:`ParameterDict`
          which match some given regular expressions.
  
          For example, collect the specified parameters in ['conv1_weight', 'conv1_bias', 'fc_weight',
