[英]array is not callable in python “'numpy.ndarray' object is not callable”
I am working on a neural network and when i try to shuffle the two numpy.ndarray i get this error. 我正在使用神经网络,当我尝试将两个numpy.ndarray改组时,出现此错误。 I tried rechecking the shuffle function format and cannot find any faults with that.
我尝试重新检查随机播放功能格式,但找不到任何错误。 Please help
请帮忙
train_images,train_labels = shuffle(train_images,train_labels)
TypeError
Traceback (most recent call last)

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
Thanks 谢谢
Have a look at the docs of random.shuffle(x[, random]) 看看random.shuffle(x [,random])的文档
The optional argument random is a 0-argument function returning a random float in [0.0, 1.0);
可选参数random是一个0参数的函数,返回[0.0,1.0)中的一个随机浮点数; by default, this is the function random()
默认情况下,这是函数random()
in your case you pass train_labels, which, according to error message is numpy.ndarray, not function 在您的情况下,您传递了train_labels,根据错误消息它是numpy.ndarray,不起作用
There are two functions named shuffle
that you may want to use, and none of them works the way you expect. 您可能要使用两个名为
shuffle
函数,但它们都不符合您的期望。
random.shuffle(x, random=None)
shuffles list x
using function random
. random.shuffle(x, random=None)
使用random
函数对列表x
进行random.shuffle(x, random=None)
。
numpy.random.shuffle(x)
shuffles a NumPy array x
. numpy.random.shuffle(x)
NumPy数组x
。
Both functions can shuffle only one array at a time, but you want to shuffle two arrays, and you want to shuffle them consistently. 这两个函数一次只能混洗一个数组,但是您想混洗两个数组,并且希望始终对它们进行混洗。 Consider building a pandas Series, shuffling ("sampling") the Series, and then splitting it into values and labels again:
考虑构建一个熊猫系列,对系列进行改组(“采样”),然后再次将其拆分为值和标签:
import pandas as pd
series = pd.Series(train_images, index=train_labels)
shuffled = series.sample(series.size)
train_images_shuffled = shuffled.values
train_labels_shuffled = shuffled.index
