Hi all,
I would like to know if anybody knows a work around in pytables that will allow
to regain numpy's behavior with repeated indices. See code below.
import numpy as np
import tables
N=5
M=5
A=np.arange(N*M, dtype=float).reshape(N,M)
with tables.openFile("file.h5", "w") as f:
B=f.createCArray(f.root,"B", tables.Float64Atom(), (N,M))
B[:]=A
print A[0,[0,1,2]]
print B[0,[0,1,2]]
print A[0,[0,1,2,0]]
print B[0,[0,1,2,0]] # However: IndexError: Selection lists cannot have
repeated values
$ python repeated_indices.py
[ 0. 1. 2.]
[ 0. 1. 2.]
[ 0. 1. 2. 0.]
Traceback (most recent call last):
File "repeated_indices.py", line 19, in <module>
print B[0,[0,1,2,0]] # However: IndexError: Selection lists cannot have
repeated values
File
"/share/distro/python/2.7.2/lib/python2.7/site-packages/tables/array.py", line
692, in __getitem__
selection, reorder, shape = self._fancySelection(key)
File
"/share/distro/python/2.7.2/lib/python2.7/site-packages/tables/array.py", line
622, in _fancySelection
"Selection lists cannot have repeated values")
IndexError: Selection lists cannot have repeated values
Best regards,
Ask
