Description

🐛 Describe the bug

There are following issues:

  1. passing Parameter as argument instead of Tensor causes recompilation
  2. setting torch._dynamo.mark_dynamic on Parameter has no effect
  3. passing tensor of size (1,1) causes recompilation with a strange guard failure - 2 <= L['x'].size()[0]
  4. using torch._dynamo.mark_dynamic(x, 0, min=0) causes error not simple sympy type <class 'NoneType'>
  5. using torch._dynamo.mark_dynamic(x, 0, min=0, max=65536) causes error CONSTRAINTS_VIOLATED

I've checked on 2.4.0 and on nightly
