title: Cuda: library nvvm not found
body: <p>I am trying to run the code below but an error is reported:</p>
  
  <p><strong>NvvmSupportError: libNVVM cannot be found. Do <code>conda install
  cudatoolkit</code>: library nvvm not found</strong></p>
  
  <p>My development environment is: Ubuntu 17.04, Spyder/Python3.5 and I have installed via conda (numba and cudatoolkit). Nvidia GPUs (GTX 1070 and GTX 1060).</p>
  
  <pre><code>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)
  </code></pre>
  
  <p>Does anyone know how to solve this problem?</p>
