batch-iterator

Usefull python implementation of batch iterator.

limitations

can only iterate on numpy arrays(or on the objects, convertable to them)

requirements

numpy

usage

x = np.arange(10)
y = np.arange(10,20)
z = np.arange(10*10).reshape((10,-1))
for x_b,y_b,z_b in iterate_minibatches(x,y,z, batchsize=2,shuffle = False):
    print("batch :")
    print(x_b, y_b, z_b)

Outputs:

batch :

[0 1] [10 11]

[[ 0 1 2 3 4 5 6 7 8 9]
[10 11 12 13 14 15 16 17 18 19]]

batch :

[2 3] [12 13]

[[20 21 22 23 24 25 26 27 28 29]
[30 31 32 33 34 35 36 37 38 39]]

batch :

[4 5] [14 15]
[[40 41 42 43 44 45 46 47 48 49]
[50 51 52 53 54 55 56 57 58 59]]

batch :

[6 7] [16 17]

[[60 61 62 63 64 65 66 67 68 69]
[70 71 72 73 74 75 76 77 78 79]]

batch :

[8 9] [18 19]

[[80 81 82 83 84 85 86 87 88 89]
