Building wheel for llvmlite ... error

[jeffenhuang]

hi there, maybe this is not a issue but an error that I faced when I install ensemble_boxes with the following command:

pip install ensemble_boxes

My environment is Jetson Xavier:

• Ubuntu:18.04 LTS
• ARMv8 Processor rev 0 (v8l) × 6
• NVIDIA Tegra Xavier (nvgpu)/integrated
• Conda 4.10.3

To reproduce:
1 create a conda environment named pytorch1
2 install pytorch via the following link https://forums.developer.nvidia.com/t/pytorch-for-jetson-version-1-10-now-available/72048
In my case, I used the python 3.6 and pytorch v1.10.0
3 After successful installed use
'pip install ensemble_boxes'

4 No error if I use python 3.8 and with cpu version pytorch.

Error occurs:

I had somewhat similar issue on macOS. Solved it with

1. brew install llvm@11
2. LLVM_CONFIG=/opt/homebrew/opt/llvm@11/bin/llvm-config pip install numba==0.55.0 version is important, 0.55.1 is not working as of Feb 20 (b/c numba 0.55.1 is in transit to numpy 1.22 but not there yet)

So, 1. Check numba installation; 2. export LLVM_CONFIG
