Description

Pcard-67005

Remove all contents in python/paddle/fluid/layers/controw_flow

Func/Class are deleted :

• Base Class of control flow (already have copies in paddle.static.nn.control_flow)

- BlockGuard

• paddle.nn.static.StaticRNN and its correlation sub-function / class (use paddle.nn.RNN / paddle.nn.RNNCellBase for create object of RNN both in dynamic and static mode)

- StaticRNN
- StaticRNNMemoryLink
- BlockGuardWithCompletion

• API While / while_loop and its correlation sub-function / class (already have copies in paddle.static.nn.control_flow)

- While
- WhileGuard
- get_inputs_outputs_in_block
- assign_skip_lod_tensor_array
- while_loop
- _deal_with_undefined_var

• sub-functions called by static.nn.cond (already have copies in paddle.static.nn.control_flow)

- _to_sequence_except_dict
- _is_sequence_except_dict
- expand_undefined_var

Func/Class are moved to 2.0 (paddle.static) :

• select_input/output (is part of paddle.static.nn.cond, offering control flow in static and dy2st)

- select_input_infer_shape
- select_input
- select_output

• sub-class called by static.nn.cond

- ConditionalBlock

• Switch and and its correlation sub-function / class ( called by piecewise_decay, which is offering LRDecay in static and dy2st)

- Switch
- ConditionalBlockGuard
