class_docstr: Ops wrapper that tries to propagate constant and index_expr values through the computation.
  
  This aims to maximize the compile time simplification possible, and convert
  indirect indexing from arange into normal static indexing.
code: def materialize_expr(
      self, expr: sympy.Expr, dtype: torch.dtype
  ) -> Any:
      # Construct a new constant/index_expr from the SymPy expression
      if isinstance(expr, sympy.Integer):
          return self._inner.constant(int(expr), dtype)
      elif expr.is_number:
          return self._inner.constant(float(expr), dtype)
      return self._inner.index_expr(expr, dtype)
