# This example shows how to read a hyperslab from an existing dataset.
|
|
#
|
|

|
|
import numpy as np
|
|
#
|
|
# Open file and read dataset.
|
|

|

|
|
print("Data in file ...")
|
|
print(data_in_file[...])
|

|
|
# Initialize data with 0s.
|
|
#
|
|
data_selected = np.zeros((8,10), dtype=np.int32)
|
|
#
|
|
# Read selection.
|

|
|
space_id = dataset.id.get_space()
|
|
space_id.select_hyperslab((1,1), (2,2), stride=(4,4), block=(2,2))
|
|
#---> Doesn't work dataset.id.read(space_id, space_id, data_selected, h5py.h5t.STD_I32LE)
|
|
dataset.id.read(space_id, space_id, data_selected)
|
|
print("Selected data read from file....")

print(data_selected[...])

|

# Close the file before exiting
