对象数组不可腌制 [英] Object array is not picklable

问题描述

我在python中制作了一个类似于以下内容的类:

I made a class in python like the following:

class myClass():
    _fields_ = [1, 2]

其中field_1&字段_2应该是整数.

where field_1 & field_2 are supposed to be integers.

然后我创建了一个数组，该数组的元素属于myClass类，如下所示:

Then I created an array that its elements are of the class myClass as following:

array = [ myClass() for i in range(5)]

当我想在变量检查器中检查array元素的值时，它会显示以下消息:

When I wanted to check the values of the elements of array in the variable inspector, it gives my the following message:

"Spyder was unable to retrieve the value of this variable from the console." 
"The error message was: Object array is not picklable"

我的问题是:如何检查数组元素的值?

My question is: How can I check the values of the elements of the array?

推荐答案

已验证，pickle可以处理问题中给出的object array.
以下内容可以正常运行.

Verifyed, pickle can handle object array given in Question.
The following works without failure.

pick_array = pickle.dumps(array)
unpick_array = pickle.loads(pick_array)

使用Python:3.4.2

Tested with Python:3.4.2

要验证您的 Spyder 能否完全显示array，请检查以下内容:

To verify your Spyder is able to show a array at all, check the following:

array = [ i for i in range(5)]

尝试使用Inspector显示变量array.

Try to show the variable array with Inspector.

如果您能够查看该变量，则是Spyder版本处理对象数组的限制.

If you are able to view the variable, it's a limitation from your Spyder Version to handle object array.
