[FIXED] np.array() gives error: inhomogeneous shape after 2 dimensions. The detected shape was (31, 3) + inhomogeneous part

Issue

I've run into an error that I've had some trouble fixing.

    finBlackSourceMoves = np.array(finBlackSourceMoves)
                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 2 dimensions. The detected shape was (31, 3) + inhomogeneous part.

I am attempting to change the following list into an numpy array:

But it's throwing the error above claiming it has an inhomogeneous part or shape, but I am certain I am sending in consistently sized sub-arrays namely two integers and an 8x8 2d array of integers.

so [integer, integer, [8][8]integer].

What could be causing this?

Solution

copy-n-paste and assign to x:

In [277]: len(x)
Out[277]: 31

In [278]: x[0]
Out[278]: 
[11,
 27,
 [[2, 3, 4, 5, 6, 4, 3, 2],
  [1, 1, 1, 1, 1, 1, 1, 1],
  [0, 0, 0, 0, 0, 0, 0, 0],
  [0, 0, 0, 0, 0, 0, 0, 0],
  [0, 0, 0, 0, 0, 0, 0, 0],
  [0, 0, 0, 0, 0, 0, 0, 0],
  [7, 7, 7, 7, 7, 7, 7, 7],
  [8, 9, 10, 11, 12, 10, 9, 8]]]

Collecting the integers into an list, and array:

In [279]: data1=[i[:2] for i in x]    
In [281]: np.array(data1).shape
Out[281]: (31, 2)

Same for the 8x8 part:

In [283]: data2=[i[2] for i in x]    
In [284]: np.array(data2).shape
Out[284]: (31, 8, 8)
