Hello Andreas,
Is there some way to change the shape of GPUArray object same as it
can be done with numpy.ndarray? The following naive code raises
exception on the last line:
import pycuda.autoinit
import pycuda.gpuarray as gpuarray
import numpy
arr = gpuarray.GPUArray((64, 64), numpy.float64)
arr.get()
arr.shape = (64 * 64,)
arr.get()
Traceback (most recent call last):
File "test.py", line 8, in <module>
arr.get()
File
"/Library/Python/2.6/site-packages/pycuda-2011.1-py2.6-macosx-10.6-i386.egg/pycuda/gpuarray.py",
line 234, in get
ary = _as_strided(ary, strides=self.strides)
File
"/Library/Python/2.6/site-packages/pycuda-2011.1-py2.6-macosx-10.6-i386.egg/pycuda/compyte/array.py",
line 116, in as_strided
return np.asarray(_DummyArray(interface, base=x))
File
"/Library/Python/2.6/site-packages/numpy-2.0.0.dev_192ac74_20110629-py2.6-macosx-10.6-universal.egg/numpy/core/numeric.py",
line 235, in asarray
return array(a, dtype, copy=False, order=order)
ValueError: mismatch in length of strides and shape
Best regards,
Bogdan
