support Mac m2 ?

[MediosZ]

The code compiles on my mac m2.
Could you confirm if the code still cannot compile on your machine?

[cuisongliu]

rust version is ?
my rust version
rustc 1.78.0 (9b00956e5 2024-04-29) .
cargo 1.78.0 (54d8815d0 2024-03-26)

[MediosZ]

mine is rustc 1.79.0 (129f3b996 2024-06-10)

[MediosZ]

I find it's the problem with imageproc, try upgrading it to 0.25.0

Error: WasiNNError(BackendError(InvalidArgument))

I need rebuild wasmedge use -WASMEDGE_PLUGIN_WASI_NN_BACKEND="Tensorflowlite" ???

[MediosZ]

Did you install WasmEdge with the installer script? I think there's one option that installed the correct build.
Otherwise, you can build it from source with this command cmake -B build -S . -GNinja -DCMAKE_BUILD_TYPE=Release -DWASMEDGE_PLUGIN_TENSORFLOWLITE=ON -DWASMEDGE_PLUGIN_WASI_NN_BACKEND=TensorFlowLite
