Can't run ort with opencv

[yevhen-k]

Can't run ort 2.0.0-alpha.4 with opencv 0.88.7 on my linux machine (haven't tried win/mac). Here is the simplest set up for repro.

sample.rs

use opencv;
use ort;
use tracing_subscriber;

fn main() -> Result<(), Box<dyn std::error::Error>> { Ok(()) }

Cargo.toml

[package]
# ...
edition = "2021"

[[bin]]
name = "sample"
path = "src/sample.rs"

[dependencies]
opencv = { version = "0.88.7" }
ort = "2.0.0-alpha.4"
tracing-subscriber = { version = "0.3.18", features = ["env-filter", "fmt"] }

Compilation

Sorry but this isn't anything ort can fix.

See here: https://groups.google.com/g/protobuf/c/RZRCnOywdSk/m/s5QvifLCBgAJ

It seems like OpenCV and ONNX Runtime are both using protobuf with reflection. I don't think it can be disabled in either library.

[yevhen-k]

Does it mean we won't be able to use both of these packages in a single project in the future?

[decahedron1]

Probably not, unless you can compile either OpenCV or ONNX Runtime to disable the problematic protobufs.

Hey, just heads-up, this is no longer true. I've managed to get it working on both Linux and Windows.
