llvmlite failed to install. Error building llvmlite

  1. How to solve llvmlite failed to install. Error building llvmlite

    Go to here and download llvmlite package for your python version, e.g. llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl for Python 3.9.
    Then install pip install llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl.
    Probably llvmlite is not yet officially supported on Python 3.9. That's why there are only unofficial builds like on this site.
    Also if you need numba then go to here and download/install numba‑0.51.2‑cp39‑cp39‑win_amd64.whl. Latest numba 0.52.0 is not yet compiled by this site owner for Python 3.9, only version 0.51.2.
    Also when installing numba you may need to pass key --no-deps to pip to ignore installing dependencies, like pip install --no-deps numba‑0.51.2‑cp39‑cp39‑win_amd64.whl because numba 0.51.2 wants a bit older version of llvmlite by default. Also few small extra dependencies are needed to be installed manually. So all steps for installing on Win Python 3.9 64-bit are:
    pip install llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl (.whl file from here).
    pip install --no-deps numba‑0.51.2‑cp39‑cp39‑win_amd64.whl (.whl file from here).
    pip install numpy importlib-metadata (small few extra dependencies via regular pip install without downloading).
    PS. Site by link mentioned above has only Windows packages. Also this site has many other popular wheels packages for Python, most of them are placed on this site because they are not currently available inside official PIP repository..

Solution 1

Go to here and download llvmlite package for your python version, e.g. llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl for Python 3.9.

Then install pip install llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl.

Probably llvmlite is not yet officially supported on Python 3.9. That’s why there are only unofficial builds like on this site.

Also if you need numba then go to here and download/install numba‑0.51.2‑cp39‑cp39‑win_amd64.whl. Latest numba 0.52.0 is not yet compiled by this site owner for Python 3.9, only version 0.51.2.

Install llvm {version} greater than 7 using command

suda apt install llvm-{version}

Than to install numba or llvmlite {package} use command

LLVM_CONFIG={path to llvm-config file} pip install {package}

For example (For llvm version=8)

LLVM_CONFIG=/usr/bin/llvm-config-8 pip install numba==0.48

llvmlite does not have support for python 3.9 yet. Uninstall python 3.9 and download python 3.8.7 and try again. This solved for the problem for me.

Solution 4

Another approach is to install llvmlite version which is directly compatible with Python 3.9.
today I successfully did that with pip install llvmlite==0.36.0rc1; you may want to use some other latest version.
