Copy part of a file#
Suppose that you want to copy all but some dataset from a file. In that case you can use
Consider the following example.
import h5py
import numpy as np
import GooseHDF5 as g5
with h5py.File("foo.h5", "w") as file:
file["/a"] = np.arange(5)
file["/b/c"] = np.arange(5)
file["/d/e/f"] = np.arange(5)
with h5py.File("foo.h5", "r") as file:
paths = list(g5.getdatasets(file))
paths.remove("/d/e/f")
with h5py.File("bar.h5", "w") as ret:
g5.copy(file, ret, paths)
ret["/d/e/f"] = file["/d/e/f"][...] * 2
print(g5.compare(file, ret, paths))
The last line includes an example on how to verify if a set of datasets is indeed the same.
