TypeError: '_AtIndexer' object is not callable

Question

pd.set_option('display.width', 100)
print(file.shape)
df = pd.read_csv('emotion_values.csv')
df = df.reset_index()
【output】：
    index  ... name
0     0    ...   a
1     1    ...   b
2     2    ...   c
3     3    ...   d  大概是这样 64行3列
F=df.drop('index', inplace=True, axis=1)
print(F)
[output]：
None (不知道为啥？)

for index, row in df.iterrows():
#   df.set_value(index, 'lengths', row['Features'].shape[0])
    df.at(index, 'lengths', row['Features'].shape[0])
报错：
Traceback (most recent call last):
File "D:/Project/pycharm/RNN/create_mfcc.py", line 86, in
df.at(index, 'lengths', row['MFCC'].shape[0])
TypeError: '_AtIndexer' object is not callable
