Thx for this answer.
I already have tried this tutorial.
I tried twice after reflashing my card (installing llvm9 instead of llvm7 because version was too old)
Now the error I get is when installing numba with pip3 install numba
“TBB version is too old, 2019 update 5, i.e. TBB_INTERFACE_VERSION >= 11005 required” is displayed
But I already have the latest tbb version on my card which is 2017~U7-8
I guess version 11005 (2019 Update5) is not compatible
