Failure due to CUDA errors when generating code for CPU?

[khaled3ttia]

Hello,

I am running into a slightly strange issue when trying to generate and run the kernel for tensor times vector.

Here is the code I am using

#include "taco.h"
#include <numeric>
#include <random>
#include <unistd.h>

#define floattype double

using namespace taco;
int main(int argc, char *argv[]) {

  std::default_random_engine gen(0);
  std::uniform_real_distribution<floattype> unif(0.0, 1.0);

  // 3D Tensor file path
  std::string tnsFile = "~/Documents/taco/test/data/3tensor.tns";

  // Used formats
  Format csr({Dense, Sparse});
  Format csf({Sparse, Sparse, Sparse});
  Format dv({Dense});

  // Load the sparse tensor
  Tensor<floattype> B = read(tnsFile, csf);

  // Prepare the tensor for the result
  Tensor<floattype> A({B.getDimension(0), B.getDimension(1)}, Dense);

  // populate a random dense vector
  Tensor<floattype> c({B.getDimension(2)}, dv);

  for (int i = 0; i < c.getDimension(0); ++i) {

    c.insert({i}, unif(gen));
  }

  c.pack();

  IndexVar i, j, k, l;

  // The main expression
  A(i, j) = B(i, j, k) * c(k);

  // GO!
  A.compile();
  A.assemble();
  A.compute();
}

The compilation command is as follows:
g++ -std=c++17 -O3 -DNDEBUG -DTACO -I ~/Documents/taco/include taco_3d.cpp -o taco_3d.x -ltaco

I get no compilation errors, but when I run the executable the error I get is:

$ ./taco_3d.x

Any pointers on how to fix this? Thank you!
