prelu op 报错信息增强 [C++ && python]

c++不合规报错检查增强

1. 使用OP_INOUT_CHECK，检查输入输出是否设置

• 输入X是否设置
  • 修改前

  Error: Input(X) of PreluOp should not be null

  • 修改后

  NotFoundError: No Input(X) found for prelu operator

• 输入alpha是否设置
  • 修改前

  Error: Input(Alpha) of PreluOp should not be null

  • 修改后

  NotFoundError: No Input(Alpha) found for prelu operator

• 输出out是否设置
  • 修改前

  Error: Output(Out) of PreluOp should not be null

  • 修改后

  NotFoundError: No Output(Out) found for prelu operator

• 反向输入out@grad是否存在
  • 修改前

  Error: Output(Out) of PreluOp should not be null

  • 修改后

  NotFoundError: No Input(Out@GRAD) found for prelu operator

2. 输入维度是否正确

• all 模式下，alpha的size必须为1
  • 修改前

  Error: For mode 'all', size of weight Alpha must be one.

  • 修改后

  InvalidArgument Error: For mode 'all', size of weight Alpha must be one.

• channel 模式下，alpha的size必须等于输入x的channel数
  • 假设alpha's size=2, x's channel=3
  • 修改前

  Error: For channel-wise mode, size of weight Alpha must be equal to the number of channels, should be 3

  • 修改后

  InvalidArgument Error: For mode 'channel', size of weight Alpha must be equal to the number of channels of input(x). But recevied alpha's size: 2, x_dim[1]: 3

• element 模式下，alpha的rank必须等于输入x的rank
  • 假设alpha's rank=2, x's rank=3
  • 修改前

  Error: For element-wise mode, rank of weight Alpha must be equal to the rank of input.

  • 修改后

  InvalidArgument Error: For mode 'element', rank of weight Alpha must be equal to the rank of input(x). But recevied alpha's rank: 2, x's rank: 3.

• element 模式下，alpha的size必须等于输入x的size
  • 假设alpha's size=20, x's size=30
  • 修改前

  Error: For element-wise mode, size of weight Alpha must be equal to the number of input.

  • 修改后

  InvalidArgument Error: For mode 'element', the size of weight Alpha must be equal to the size of input(x). But recevied alpha's size: 20, x's size: 30.

python不合规报错检查增强

• 检查 x 是否为variable，且是否dtype为float32，float64
