Unstablity of Tensor.data()

[Rick0827]

Codes with problem:

Env: WSL Ubuntu22.04 || mojo 0.7.0
For the output of the loop, expected "1.0 2.0 3.0 4.0", got

which is unstable.
But everything seems to be correct in REPL or add "print(sample[i])" to the loop.

sample owns the pointer and is destroyed after its last use. So free() is called on the pointer before you read from it. You can either keep the tensor from being destroyed by using it after you read the pointer or you can take ownership of the pointer with sample._steal_ptr().

Thanks a lot!
