[BUG] matxException thrown about matx HOT 7 CLOSED

Hello @cliffburdick,
that works well. Output from example1_simple_slice is (added original tensor output to check correctness of slice):
Tensor{int32_t} Rank: 2, Sizes:[5, 4], Strides:[4,1]
000000: 1 2 3 4
000001: 5 6 7 8
000002: 9 10 11 12
000003: 13 14 15 16
000004: 17 18 19 20
Tensor{int32_t} Rank: 2, Sizes:[2, 2], Strides:[4,1]
000000: 6 7
000001: 10 11
Tested also with example1_init and example1_permute which also yield correct results.

Thank you for your efforts and kind regards

Hi @siegLoesch, I tried to reproduce this on my platform and saw:

Tensor{int32_t} Rank: 2, Sizes:[2, 2], Strides:[4,1]
000000: 6 7
000001: 10 11

That error indicates that it can't detect the type of pointer it is for printing. Can you please print out what mtype is right before that assert?

Hello @cliffburdick, the value of mtype before the assert:
mtype before assert = 2
I checked also the Create and Permute examples which do not output mtype at all. I assume they do not enter the respective if clause:

#ifdef __CUDACC__
  cudaDeviceSynchronize();
  if constexpr (is_tensor_view_v<Op>) { ...

Thanks for your help and kind regards

That's interesting -- which GPU is this? I'm not sure why this wouldn't be triggering in our code. I can submit a patch if I can't reproduce it

from matx.

The GPU is: GeForce RTX 2060

Hi @siegLoesch can you please try the print_device branch?
