Object array is not picklable

问题:

I made a class in python like the following:

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

where field_1 & field_2 are supposed to be integers.

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

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

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"

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

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)

Tested with Python:3.4.2

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

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

Try to show the variable array with Inspector.

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