Numpy error – ValueError: setting an array element with sequence

You have struggled during hours and hours to understand why you got this damned error while compiling a complex array structure? I did. In my case I was trying to create an array of the following shape :

[  [ [0,0,1,0] , 0.5] , [ [0,1,1,0] , 0.3] , [ [1,0,1,0] , 0.2] ]

With the basic syntax, it was impossible. I first didn’t notice the problem because I wasn’t using the ‘array‘ constructor, but when I tried to append some value to my initial vector, I got the error : ValueError: setting an array element with sequence. »
