lazy_ops
Provides a class to allow for lazy transposing and slicing operations on h5py datasets
Installation
$ pip install lazy_opsUsage:
import h5py
from lazy_ops import DatasetView
dsetview = DatasetView(dataset) # dataset is an instantiated h5py dataset
view1 = dsetview.lazy_slice[1:10:2,:,0:50:5].lazy_transpose([2,0,1]).lazy_slice[25:55,1,1:4:1,:].lazy_transpose()
A = view1[:] # Brackets on DataSetView call the h5py slicing method, that returns the data
B = view1.dsetread() # same as view1[:]
