如何将“ if”语句与numpy逻辑语句一起使用

Question

我正在为我的numpy逻辑语句编写if语句。但是，似乎我尝试了所有事情，总是得到

“ ValueError：具有多个元素的数组的真值不明确。请使用a.any（）或a.all（）

很抱歉，如果这是一个愚蠢的问题。

import numpy as np 
w = 8
l = 5
s = 2
blocked = []
file_blocked = [17,20]
board = np.arange(w*l)
board = board.reshape(l,w)
start = board[s,0]
currentpoint = start
print(board)
print()

for j in range(len(file_blocked)):
  each_block = file_blocked[j]
  each_block = np.argwhere(board == each_block)
  each_block = np.hstack(each_block)
  blocked.append(each_block)



place_a = np.logical_and(np.argwhere(board == currentpoint) + [0,1] != blocked, np.argwhere(board == currentpoint) + [0,2] != blocked, np.argwhere(board == currentpoint) + [0,3] != blocked)
