numpy:vsplit

source: /numpy/lib/_shape_base_impl.py :952

Signature

def   vsplit ( ary ,  indices_or_sections )

Summary

Split an array into multiple sub-arrays vertically (row-wise).

Extended Summary

Please refer to the split documentation. vsplit is equivalent to split with axis=0 (default), the array is always split along the first axis regardless of the array dimension.

Examples

import numpy as np
x = np.arange(16.0).reshape(4, 4)
✓
x
np.vsplit(x, 2)
np.vsplit(x, np.array([3, 6]))
✗
With a higher dimensional array the split is still along the first axis. 
x = np.arange(8.0).reshape(2, 2, 2)
✓
x
np.vsplit(x, 2)
✗
