Failed building wheel for snips-nlu-rust

[laboitemail]

On raspbian stretch (RPi 3 B), trying to install snips-nlu-rust without success
not familiar with rust, don't know what I'm doing wrong

sudo apt-get install python3-venv 
mkdir snips-nlu && cd snips-nlu
python3 -m venv .env 
source .env/bin/activate 
sudo apt install rustc cargo
pip install setuptools_rust==0.8.4
pip install wheel
pip install snips-nlu-rust

getting:

error: native library `clang` is being linked to by more than one version of the same package, but it can only be linked once; try updating or pinning your dependencies to ensure that this package only shows up once
  
    clang-sys v0.26.4
    clang-sys v0.22.0
  error: cargo failed with code: 101

Any help would be appreciate; really appreciate snips-nlu on my laptop by the way
Thanks

Hi @laboitemail ,
If you plan to use Snips on a raspberry pi, you should rather have a look at the Snips Platform documentation and also join the forum.
Using the rust version of snips-nlu on a Raspi requires some non-trivial cross-compilation steps. Thus, we have built some binaries that you can install by following the instructions in the documentation linked above.
Cheers
