cbalint13 opened a new pull request #7382:
URL: https://github.com/apache/tvm/pull/7382
* Trying to lower quantized C target some simple nets reveal missing
**round**, **floor**, **ceil** translation.
```
with relay.build_config(opt_level=3):
graph, c_mod, c_params = relay.build(mod, target='c', params=params)
```
* Network looks like the one below, notice for example the ```round```
operations:
```
#[version = "0.0.5"]
def @main(%input_3: Tensor[(1, 1, 129, 124), float32]) -> Tensor[(?, 8),
float32] {
%0 = dyn.image.resize(%input_3, meta[relay.Constant][0] /* ty=Tensor[(2),
int64] */, size=[]) /* ty=Tensor[(1, 1, ?, ?), float32] */;
%1 = multiply(%0, 16f /* ty=float32 */) /* ty=Tensor[(1, 1, ?, ?),
float32] */;
%2 = round(%1) /* ty=Tensor[(1, 1, ?, ?), float32] */;
.....
.....
```
* The errors encountered:
```
TVMError: Unresolved call Op(tir.round)
TVMError: Unresolved call Op(tir.floor)
TVMError: Unresolved call Op(tir.ceil)
```
--------
* This simple patch address the issue.
@jroesch @masashi @mdw-octoml Please help me review.
