numpy.core._exceptions._UFuncNoLoopError: ufunc 'add' did not contain a loop with signature

想要给以下表格的每个数字都加上1

代码如下

from datetime import datetime
import pandas as pd
import numpy as np
import math
df = pd.read_csv(r'C:\Users\Administrator\Desktop\1.csv')
print(df, type(df))
x = df.iloc[:3]['A']
print(x, type(x))
print(np.array(list(x))+1)

出现以下错误提示，尝试用各种方法将字符转为数字，但均未成功，该如何解决？

下有代码，可直接复制使用。如有帮助，敬请采纳，你的采纳是我前进的动力，O(∩_∩)O谢谢！！！！！！！！

import pandas as pd
import numpy as np

df = pd.read_csv(r'C:\Users\Administrator\Desktop\1.csv')
print(df, type(df))
x = df.iloc[:3]['A']
print(x, type(x))

x = ''.join(x.tolist()).replace('][', ',').replace(']', '').replace('[', '')
x_np = np.fromstring(x, dtype=float, sep=',').reshape(-1, 2)

print(x_np + 1)

可以尝试先把立面的数据提取出来，在python里面变成数字再加一，然后储存回csv

def a(row):
    for i in range(len(row)):
        row[i] = int(row[i])
    return row

df['A'] = df['A'].apply(a)
