numpy fromstring贬值，改用frombuffer

Question

在使用numpy 1.18.1的Python代码中]

`def printBoard（self）：当前= self.player其他= self.player％2 +1

    currBin   = '{:049b}'.format(self.current_position)
    currRev = currBin[::-1]

    cArr = (np.fromstring(currRev,'u1') - ord('0'))*current

    other_position = self.current_position^self.mask
    othBin   = '{:049b}'.format(other_position)
    othRev = othBin[::-1]

    oArr = (np.fromstring(othRev,'u1') - ord('0'))*other

    tArr =  oArr+cArr

    brd = np.reshape(tArr,(7,7),order = 'F')
    for y in range(bitBoard.HEIGHT,-1,-1):
        for x in range(bitBoard.WIDTH):
            print(brd[y,x],end = ' ')
        print()
    print()
    `
行：

cArr = (np.fromstring(currRev,'u1') - ord('0'))*current
给出以下警告：

DeprecationWarning: The binary mode of fromstring is deprecated, as it behaves surprisingly on    unicode inputs. Use frombuffer instead
  cArr = (np.fromstring(currRev,'u1') - ord('0'))*current
用'frombuffer'替换'fromstring'会出现以下错误：

cArr = (np.frombuffer(currRev,'u1') - ord('0'))*current

TypeError: a bytes-like object is required, not 'str'
尽管进行了一些Google搜索，但我找不到应该使用的内容。有人可以帮忙吗？

谢谢。

在使用numpy 1.18.1`的Python代码中def printBoard（self）：current = self.player other = self.player％2 +1 currBin ='{：049b}'。format（self.current_position）currRev =。 ..

Answer 1

您的代码的相关部分是产生currRev的部分。由此我可以构建这个示例：
