PyOpenCL第一次运行时返回错误，然后仅返回“无效程序"错误；例子也行不通 [英] PyOpenCL returns errors the first run, then only 'invalid program' errors; examples also not working

问题描述

我正在尝试使用pyOpenCL绑定运行OpenCL内核，以便在GPU上运行.我试图将内核加载到程序中.我运行了一次程序，但出现错误.我不更改代码再次运行，并收到了另一个无效程序"错误.

I am trying to run an OpenCL kernel using the pyOpenCL bindings, to run on the GPU. I was trying to load the kernel to my program. I ran my program once and got an error. I ran it again without changing the code and got a different, 'invalid program' error.

在使用pyOpenCL的我自己的程序以及示例程序中，这种情况一直在发生.我可以在CPU和GPU上通过C++绑定使用OpenCL，没有问题.所以我认为这是pyOpenCL绑定特有的问题.

This keeps happening to my own programs using pyOpenCL and also on example programs. I am able to use OpenCL through the C++ bindings, on both the CPU and GPU, with no problems. So I think this is a problem specific to the pyOpenCL bindings.

我的操作系统是Linux Mint 17.1 64位.我的GPU是Intel HD Graphics 4000第三代处理器.我通过安装beignet获得了对OpenCL的支持(请参见此处)) .我正在使用python 2.7和OpenCL 1.2.

My OS is Linux Mint 17.1 64 bit. My GPU is an Intel HD graphics 4000 3rd Gen processor. I got the OpenCL support for it by installing beignet (see here). I am using python 2.7 and OpenCL 1.2.

我第一次运行程序时，出现此错误:

The first time I ran my program, I got this error:

File "/usr/lib/python2.7/dist-packages/pyopencl/__init__.py", line 463, in kernel_call
    self.set_args(*args)
File "/usr/lib/python2.7/dist-packages/pyopencl/__init__.py", line 488, in kernel_set_args
    % (len(args), self.num_args))
AssertionError: length of argument list (4) and CL-generated number of arguments (9) do not agree

但是随后我再次运行它，并开始出现此不同错误:

But then I ran it again, and started getting this different error:

File "/usr/lib/python2.7/dist-packages/pyopencl/__init__.py", line 206, in _build_and_catch_errors
    raise err
pyopencl.RuntimeError: clBuildProgram failed: invalid program - 

Build on <pyopencl.Device 'Intel HD Graphics Family' on 'Experiment Intel Gen OCL Driver' at 0x7fb77bf21720>:

(options: -I /usr/lib/python2.7/dist-packages/pyopencl/cl)
(source saved as /tmp/tmplLRgy9.cl)

我在此处下载了pyOpenCL示例之一，但我得到了相同的结果问题:我第一次运行它，我得到了:

I downloaded one of the pyOpenCL examples for here but I got the same problem: the first time I ran it, I got:

File "/usr/lib/python2.7/dist-packages/pyopencl/__init__.py", line 436, in __getattr__
    return self.event.get_profiling_info(inf_attr)
pyopencl.RuntimeError: clGetEventProfilingInfo failed: profiling info not available

...然后我再次运行它，并且从以前收到了相同的无效程序"错误.

...and then I run it again, and I got the same 'invalid program' error from before.

我不明白为什么第二次运行程序时错误会更改，因为两次运行之间的代码没有更改.

I don't understand why the error changes the second time I run the programs, since I didn't change anything in the code in between runs.

希望这很清楚，谢谢.

推荐答案

我通过卸载beignet并安装了最新版本beignet 1.1.0来解决了(某种)问题，找到了

I solved it (sort of) by uninstalling beignet and installing the latest version, beignet 1.1.0, found here.

但是，使程序能够检测我的GPU设备并正常工作的唯一方法是以root身份运行它们.可能会针对该特定问题发布不同的问题.

However, the only way to get the programs to detect my GPU device and work with no problems is by running them as root. Will probably post a different question for that specific issue.
