ExecError: error invoking 'nvcc --version': [Errno 2] No such file or directory: 'nvcc': 'nvcc'

Question

I am trying this code on my spyder(python3).

import pycuda.autoinit
import pycuda.driver as drv
import numpy

from pycuda.compiler import SourceModule
mod = SourceModule("""
__global__ void multiply_them(float *dest, float *a, float *b)
{
  const int i = threadIdx.x;
  dest[i] = a[i] * b[i];
}
""")

multiply_them = mod.get_function("multiply_them")

a = numpy.random.randn(400).astype(numpy.float32)
b = numpy.random.randn(400).astype(numpy.float32)

dest = numpy.zeros_like(a)
multiply_them(
        drv.Out(dest), drv.In(a), drv.In(b),
        block=(400,1,1), grid=(1,1))

print (dest-a*b)

But couldn't run the code.

ExecError: error invoking 'nvcc --version': [Errno 2] No such file or directory: 'nvcc': 'nvcc'

My nvcc -- version is

nvcc: NVIDIA (R) Cuda compiler driver

I have tried running the code on terminal. Then its running , but from the sourceModule line itself it shows errors.

Also i have tried on my Jupiter notebook and on other Cuda installed system. But couldn't identify the problem. Any help is appreciable.

Answer 1

Its working on python2 virtual environment through terminal.
