cyx-6 opened a new pull request, #13859:
URL: https://github.com/apache/tvm/pull/13859
This PR refactors the output of `assert_structural_equal`. Different from
the direct printing mismatching nodes, in the old version, the improved one
will print the whole scripts, with mismatching nodes underlined. For example,
we have following functions
```python
@T.prim_func
def func1(a: T.handle, b: T.handle):
A = T.match_buffer(a, (128, 128))
B = T.match_buffer(b, (128, 128))
@T.prim_func
def func2(a: T.handle, b: T.handle):
A = T.match_buffer(a, (128, 128))
B = T.match_buffer(b, (128, 256))
```
the log of `assert_structural_equal(func1, func2)` will be like
```python
ValueError: StructuralEqual check failed, caused by lhs:
# from tvm.script import tir as T
@T.prim_func
def main(a: T.handle, b: T.handle):
A = T.match_buffer(a, (128, 128))
B = T.match_buffer(b, (128, 128))
^^^
T.evaluate(0)
and rhs:
# from tvm.script import tir as T
@T.prim_func
def main(a: T.handle, b: T.handle):
A = T.match_buffer(a, (128, 128))
B = T.match_buffer(b, (128, 256))
^^^
T.evaluate(0)
```
instead of
```python
ValueError: StructuralEqual check failed, caused by lhs:
128
and rhs:
256
```
which is not readable sometimes.
