谷歌Colabrotary期望一个缩进块

Question

Google Colabrotary因缩进错误而失败：应为缩进块

代码

def zero_pad(X, pad):
    X_pad = np.pad( X, ((0,0), (pad,pad), (pad,pad), (0,0)), 'constant', 
    constant_values)
    return X_pad`

错误

File "<ipython-input-4-a7791c18ae10>", line 2
    X_pad = np.pad( X, ((0,0), (pad,pad), (pad,pad), (0,0)), 'constant', constant_values)
        ^
***IndentationError: expected an indented block***

Answer 1

只需删除def块前的空格，并按如下方式编码：

import numpy as np
def zero_pad(X, pad):
  X_pad = np.pad(X, ((0,0), (pad,pad), (pad,pad), (0,0)), 'constant', constant_values) 
  return X_pad
