Prior to commit, many unit tests were implemented as
assert tvm.ir.structural_equal(output, expected)
. While this is correct, it doesn't provide much information when the test fails. Thetvm.ir.assert_structural_equal
method performs the equivalent check, but displays the exact location where a mismatch occurs.This commit replaces all use of
assert tvm.ir.structural_equal
withtvm.ir.assert_structural_equal
.
