d-smirnov opened a new pull request #6513:
URL: https://github.com/apache/incubator-tvm/pull/6513
An attempt to fix an issue which appeared when ConverLayout pass
runs on quantized binary operations like qnn.add:
def before():
x = relay.var("x", shape=(2, 2))
y = relay.var("y", shape=(1, 2))
return relay.Function(
[x, y],
relay.qnn.op.add(
x,
y,
lhs_scale=relay.const(0.0156863, "float32"),
lhs_zero_point=relay.const(127, "int32"),
rhs_scale=relay.const(0.0117647, "float32"),
rhs_zero_point=relay.const(85, "int32"),
output_scale=relay.const(0.0235294, "float32"),
output_zero_point=relay.const(128, "int32"),
),
)
The issue manifested itself as
