How to reshape 4d array to 2d array in numpy

Question

I have a 4d array of shape like this. It has total 18*100 = 1800 rows and 30 dimensional outputs per row

(18, 100, 30, 1, 1)

i want to convert or reshape this into 2d array, the easiest way

(1800,30)

Sorry for being so naive with numpy, but please i am a novice user. Any help much appreciated.

Answer 1

numpy.reshape(input_in_4D, (1800,30))

Of course this just converts the input in the default order (meaning you "unroll" the input array from inner to outer); if you need special ordering, you should read up on slicing.

Answer 2

You can use reshape method:

newArray = oldArray.reshape(1800,30)
