Failing to install llvmlite on Raspberry Pi 4

[ViliamVadocz]

I am trying to install llvmlite on my Raspberry Pi 4 (Model B).

When I try pip3 install llvmlite I get this:

The docs mention that I don't need to install LLVM, but I tried apt-get install llvm anyway. It didn't seem to help. I am primarily a Windows user so I am not that familiar with apt-get but I also tried apt-get install llvm=10.0.0, but I received an error: Version '10.0.0' for 'llvm' was not found.

I tried pip3 install librosa==0.4.2 mentioned in an old issue, but that also seemed to do nothing useful.

Do you have any suggestions for what else I could try?

Thanks for the report. The installation instructions for Numba (which depends on llvmlite) should work as they will provide binary packages (not sure which OS you are running, 32 or 64 bit, but one of these should work):

• ARMv7l
• AArch64

[ViliamVadocz]

Thank you very much!

I ran lscpu and found that I have ARMv7l architecture. I installed berryconda and with that I was able to install llvmlite. It works great, except for the fact that berryconda is python 3.6. I would much prefer python 3.7+

My original was problem solved so I am closing this issue, but if you know of a way to get berryconda to work for python 3.7+, please let me know.

I tried berryconda, miniconda but getting no success in installing llvmlite package. I am having ARMv7I architecture.
