Python和OpenCL的問題

我試圖運行下面的腳本：Python和OpenCL的問題

import silx 
from silx.image import sift 
from PIL import Image 
import numpy 
import scipy.ndimage 
from silx.opencl import ocl, pyopencl, kernel_workgroup_size 

img1 = numpy.asarray(Image.open('1.jpg')) 
img2 = numpy.asarray(Image.open('2.jpg')) 

alignPlan = sift.LinearAlign(img1, devicetype='GPU') 
img2_aligned = alignPlan.align(img2)

但是，得到下面的錯誤，我不漂亮知道這意味着什麼：

編輯：下面是「clinfo」輸出：

     but it seems to support up to OpenCL 2.1 too.

你對我怎麼能解決的想法這個問題？

謝謝。

什麼clinfo輸出？ – Jovasa

@Jovasa感謝您的評論。我在我的問題中添加了「clinfo」信息。 – Simplicity

我有一個類似的問題，並找到一個解決方案，移除Beignet OpenCL驅動程序解決了這個問題。

sudo dnf remove beignet

，我發現我的solution
