数组在python中不可调用“'numpy.ndarray'对象不可调用"； [英] array is not callable in python "'numpy.ndarray' object is not callable"

问题描述

我正在研究一个神经网络，当我尝试对两个 numpy.ndarray 进行混洗时出现此错误.我尝试重新检查 shuffle 函数格式，但找不到任何错误.请帮忙

I am working on a neural network and when i try to shuffle the two numpy.ndarray i get this error. I tried rechecking the shuffle function format and cannot find any faults with that. Please help

train_images,train_labels = shuffle(train_images,train_labels)
TypeError                                 
Traceback (most recent call last)
<ipython-input-8-b3f4173331ac> in <module>
 18     print("Training the Network")
 19     for i in range(epoch):
 20     --> train_images,train_labels = shuffle(train_images,train_labels)
 21         for offset in range (0,no_eg,batch_size):
 22             end = offset+batch_size

/usr/lib/python3.5/random.py in shuffle(self, x, random)
275             for i in reversed(range(1, len(x))):
276                 # pick an element in x[:i+1] with which to exchange x[i]
277            -->  j = _int(random() * (i+1))
278                 x[i], x[j] = x[j], x[i]
279 

TypeError: 'numpy.ndarray' object is not callabl

谢谢

推荐答案

查看 random.shuffle(x[, random])

可选参数 random 是一个 0 参数函数，返回一个在 [0.0, 1.0) 中随机浮动；默认情况下，这是函数 random()

The optional argument random is a 0-argument function returning a random float in [0.0, 1.0); by default, this is the function random()

在您的情况下，您通过了 train_labels，根据错误消息，它是 numpy.ndarray，而不是函数

in your case you pass train_labels, which, according to error message is numpy.ndarray, not function
