CompilerWarning今天醒來後突然得到與OpenCL的

C:\Python27\lib\site-packages\pyopencl\__init__.py:61: CompilerWarning: Non-empty compiler output encountered. Set the environment variable PYOPENCL_COMPILER_OUTPUT=1 to see more. 
    "to see more.", CompilerWarning) 
C:\Python27\lib\site-packages\pyopencl\cache.py:101: UserWarning: could not obtain cache lock--delete 'c:\users\User\appdata\local\temp\pyopencl-compiler-cache-v2-uiduser-py2.7.3.final.0\lock' if necessary 
    % self.lock_file) 

當我運行任何形式的PqOpenCL代碼,例如:

import numpy 
import pyopencl as cl 
import pyopencl.array as clarray 
from pyopencl.reduction import ReductionKernel 

ctx = cl.create_some_context() 
queue = cl.CommandQueue(ctx) 
krnl = ReductionKernel(ctx, numpy.float32, neutral="0", 
         reduce_expr="a+b", map_expr="x[i]*y[i]", 
         arguments="__global float *x, __global float *y") 
x = clarray.arange(queue, 400, dtype=numpy.float32) 
y = clarray.arange(queue, 400, dtype=numpy.float32) 
m = krnl(x, y).get() 

樣品和解決方案的一部分,從here

來到

解決方案建議回滾numpy,我從1.8.0到1.7.2但仍然是相同的問題

添加爲每建議

import os os.environ['PYOPENCL_COMPILER_OUTPUT'] = '1'

C:\Python27\lib\site-packages\pyopencl\__init__.py:57: CompilerWarning: From-source build succeeded, but resulted in non-empty logs: 
Build on <pyopencl.Device 'Intel(R) HD Graphics 4000' on 'Intel(R) OpenCL' at 0x51eadff0> succeeded, but said: 

fcl build 1 succeeded. 
fcl build 2 succeeded. 
bcl build succeeded. 

    warn(text, CompilerWarning) 
+0

根據警告文本,設置PYOPENCL_COMPILER_OUTPUT = 1來查看警告實際所說的內容。第二個警告還包含刪除鎖定文件以允許緩存進程正常工作的說明。 – jprice

import os 
os.environ['PYOPENCL_COMPILER_OUTPUT'] = '1' 

這樣做是爲了看看編譯器的輸出,我之前得到了同樣的信息。這只是intel opencl編譯器說它已經對opencl內核進行了優化。
