test errors about libgpuarray HOT 7 CLOSED

I looked into "NameError: global name 'array' is not defined".
First, 'array' is not imported in _array.py. Second, 'array' doesn't have GpuArray but 'gpuarray' does.

I ran the followings in pygpu directory:

import array
array.GpuArray
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'module' object has no attribute 'GpuArray'

import gpuarray
gpuarray.GpuArray
<type 'pygpu.gpuarray.GpuArray'>

Is 'array' supposed to be 'gpuarray'?

from libgpuarray.

There was an 'array.py' file that was renamed to '_array.py' because of name conflicts. Maybe there is a leftover array.pyc file, which you should delete.

As for the GpuArrayException, from the sample you posted, it seems there are problems with your blas library. The error just indicates that the blas library returned an error.

Thank you for your answers.

I looked for array.pyc by executing "find / -name array.pyc" and got nothing. "ls" in pygpu returns init.py blas.py dtypes.py gpuarray.h gpuarray_api.h parser.py scan.py tools.pyc
init.pyc blas.pyc dtypes.pyc gpuarray.py numpy_compat.h parser.pyc scan.pyc
_array.py blas.so elemwise.py gpuarray.pyc operations.py reduction.py tests
_array.pyc blas_api.h elemwise.pyc gpuarray.so operations.pyc reduction.pyc tools.py.

When you say "blas library" do you mean clblas? This machine is a mac and I didn't install BLAS as the installation page says OSX comes with the Accelerated framework.

from libgpuarray.

Yes I mean clBLAS. It seems there is a problem with your intallation (which might just be that it is trying to run on the CPU and clBLAS doesn't like that).

Also, you have an old install of pygpu which does have the array.py file as evidenced by:

File "/Library/Python/2.7/site-packages/pygpu-0.2.1-py2.7-macosx-10.9-intel.egg/pygpu/array.py", line 134, in __divmod_

Get rid of that install and the problem should go away.

Thanks for your help. I really appreciate it. I will look into my clBLAS installation.

I don't have array.py in the pygpu directory. underscore character (_) right before array.py was italicizing it. The following is the error message with escaping:
ERROR: pygpu.tests.test_elemwise.test_divmod('uint64', (50,), array(2.450000047683716, dtype=float32))

I get a Floating Point Exception: 8 at some point when running the test suite on my machine. However this is after the tests for elemwise operations which seem to be the source of your array problems.

I don't have much time to investigate this right now, but I should have some next week.

from libgpuarray.

I just realized that the following code line:

File "/Library/Python/2.7/site-packages/pygpu-0.2.1-py2.7-macosx-10.9-intel.egg/pygpu/_array.py", line 134, in __divmod__
if not isinstance(other, array.GpuArray):

should read:

if not isinstance(other, gpuarray.GpuArray):

It never had any version that read array.Gpuarray, so something modified that code and this is what broke it. I'm assuming that this is the cause of this problem and therefore closing the ticket.
