我试图运行下面的代码,但报告错误:

NvvmSupportError:找不到libNVVM.执行conda install cudatoolkit:找不到库nvvm

我的开发环境是:Ubuntu 17.04,Spyder/Python3.5,我通过conda(numba和cudatoolkit)安装.Nvidia GPU(GTX 1070和GTX 1060).

import numpy as np
from timeit import default_timer as timer
from numba import vectorize

@vectorize(["float32(float32, float32)"], target='cuda')     
def VecADD(a,b):
    return a+b        

n = 32000000
a = np.ones (n, dtype=np.float32) 
b = np.ones (n, dtype=np.float32)     
c = np.zeros(n, dtype=np.float32) 

start = timer()
C = VecADD(a,b)
print (timer() - start)

有谁知道如何解决这个问题？
