Numpy Array Error With dtype = numpy.uint8

Navigation
1

The code below works normally, however the elements are "objects". 

M = numpy.array([[1,2,3],[1,2],[1,2,3,4]],dtype=object)

However, when I run the code below, I get the message "setting an array element with a sequence". The question is: how to make an INT array that has this characteristic "[1,2,3], [1,2], [1,2,3,4]"? 

M = numpy.array([[1,2,3],[1,2],[1,2,3,4]],dtype=numpy.uint8)

works if vectors have the same number of elements 

M = numpy.array([[1, 2, 3], [1, 2, 3], [1, 2, 3]], dtype=numpy.uint8)
