Erros when parsing Relay Text Format with relay.fromtext()

I’m trying to load a graph in text format with relay.fromtext(). Here’s the text:
graph="""
v0.0.1
fn (%x: Tensor[(1, 1, 100, 100), float32], %v1: Tensor[(10, 100), float32], %v4: float32)
{
%0 = transpose(%v1, axes=[1, 0])
%1 = transpose(%0, axes=[1, 0])
%2 = nn.dense(%x, %1, units=None)
add(%2, %v4)
}
“”"
Two errors are reported:

  1. token recognition error at: ‘.’
    I searched the grammar file Relay.g4, are there’s no rules for ‘.’
  2. “axes” cannot be recognized.
    This error seems to indicate that currently attributes cannot be parsed.

So I’m wondering if I want to load a graph built by relay APIs (previous graph is just built by APIs), should I modify the grammar file? Or does TVM team have a plan for supporting more complex grammar?
