Hi,
There is a const Tensor& tensor in a .cpp file, and the tensor is of cudaTensor type. I want to access the elements within the tensor and make a change. I create .cu file to define a kernel to change the elements within the tensor, but the problem here is that
I am not sure if it is a correct way to pass tensor.data_ptr() as the parameter to cuda kernel and use *tensor.data_ptr() to access the element in the tensor in the cuda kernel. If not, is there other way to access the data?
What I tried is as following:
in .cpp
tensor_change((float*)tensor.data_ptr(), number);
in .cu
global  void tc(float* po, int number) {
printf("%d\n", number);
printf(“pval = %p\n”, po);
printf(“val = %f\n”, *po);
printf(“val_next = %f\n”, *(po+1)); }
void tensor_change(float* po, int number){
tc<<<1, 1>>>(po, number); }
The result is:
2856768
pval = 0x7faf27200000
val = 0.000000
val_next = 0.000000
Any help will be appreciated!
Thanks
