8 years ago The memory errors indicate something is wrong at runtime. I don't know what.
The errors in float16, indicate that there probably is a problem with float16 support. It hasn't been tested much with the OpenCL backend so it would not surprise me that there is a problem.

8 years ago Just to tell, we don't have time to finish OpenCL support. There is more work needed then this. We need people from outside the current team to come and help us make it to have it working.
Are you interrested?

8 years ago As much as I'd like to hope to get into GPGPU programming, I have too much other stuff going in my life at the moment. I can try figuring out what's causing these tests to fail on my machine though.

8 years ago I'll also add that more tests fail if you use a numpy compiled Intel MKL. I've pasted the errors below (they're repeated for all the tested types):

For most of these errors it seems like numpy is using nonsensical values. I would not consider this a pygpu bug but rather a numpy one. We do have versions of numpy compiled with MKL that work so something is wrong with yours.

8 years ago Did you compile numpy from the dev version and not a release version? If so, the put non sensible value for stride in some cases.

7 years ago The new test failures are indeed from the special stride values that numpy is using in the development versions.
The one error that worries me is the unaligned array one in pygpu.tests.test_tools.test_check_args_collapse_2, but I can't manage to reproduce it.
I compiled and tested the latest
libgpuarrayon Ubuntu 14.04 with the pygpu package. When I run: $ DEVICE="opencl0:0" python -c "import pygpu;pygpu.test()", I get the following errors:Are these errors serious? Is it a problem with the code or have I built something incorrectly?
