Question

我的使用pypy的Dockerfile失败，出现FileNotFoundError：[错误2]没有这样的文件或目录：安装llvmlite时出现“ llvm-config”，它是numba的依赖项，在我的要求中列出。

我试图遵循并更新此处的说明 Python numba / llvmlite on Debian 8 - i can't build llvmlite

我的错误更详细：

我不希望安装conda这么重。有没有办法为pypy实现numba安装？

FROM pypy:3.6-slim-stretch

RUN wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | apt-key add - 15CF4D18AF4F7421

#... other stuff

RUN apt-get clean && apt-get -y update
RUN apt-get -y install python3-dev \
    && apt-get -y install build-essential

# Add requirements
COPY requirements.txt /tmp/

# Install sphinx first as it does not work inside requirements
RUN pip install -U pip && pip install -U sphinx && pip install numpy && pip install cython &&  \
  pip install -r /tmp/requirements.txt

我希望在pypy上使用numba干净构建docker映像

Answer 1

解决方法如果该错误在4月17日之后出现（他们发布了新版本，请参见history）。解决方法是尝试安装以前的版本

library(data.table)
y[, num := as.numeric(sub(".*rating[^0-9]*(\\d+)\\b.*", "\\1",
         status, ignore.case = TRUE))]
y
#                      status num
#1: client rating 01 approved   1
#2:   John Rating: 2 reproved   2
#3:          Customer rating9   9

Answer 2

“真实”的解决方案是鼓励llvmlite和/或numba释放出一个pypy轮子。但是对于眼前的问题...

至少由于apt-file，您会以某种方式丢失llvm安装：

$ apt-file find llvm-config |grep llvm-6
llvm-6.0: /usr/bin/llvm-config-6.0
llvm-6.0: /usr/lib/llvm-6.0/bin/llvm-config
llvm-6.0: /usr/share/man/man1/llvm-config-6.0.1.gz

Answer 3

这为我修复了它-

RUN echo "deb http://apt.llvm.org/xenial/ llvm-toolchain-xenial-8 main" >> /etc/apt/sources.list
RUN echo "deb-src http://apt.llvm.org/xenial/ llvm-toolchain-xenial-8 main" >> /etc/apt/sources.list

RUN apt-get install -y --no-install-recommends libedit-dev build-essential
RUN apt-get install -y --no-install-recommends  llvm-8 llvm-8-dev

RUN LLVM_CONFIG=/usr/bin/llvm-config-8 pip3 install enum34 llvmlite numba

使用版本8，因为最新的llvm版本出错-

RuntimeError: Building llvmlite requires LLVM 7.0.x, 7.1.x or 8.0.x, got '3.7.1'

参考-https://apt.llvm.org/

Answer 4

目前 numba won't install on python 3.9。

我将我的基本 docker 映像从 python:3.9-slim 更改为 python:3.8-slim，然后 pip install numba 成功

Answer 5

对于在 macOS 上的 Python 3.9 上安装 numba，以下工作：

# install llvm using MacPorts
sudo port install llvm-10
sudo port install llvm_select
sudo port select --set llvm mp-llvm-10
# set environment variable used when building `llvmlite`
export LLVM_CONFIG=/opt/local/bin/llvm-config

# clone, build, and install `llvmlite`
# http://llvmlite.pydata.org/en/latest/admin-guide/install.html#compiling-llvmlite
git clone git@github.com:numba/llvmlite.git
cd llvmlite
python setup.py build
python runtests.py
python setup.py install
cd ..

# clone, build, and install `numba`
# https://numba.readthedocs.io/en/stable/user/installing.html#installing-from-source
git clone git@github.com:numba/numba.git
cd numba
export PATH=/usr/bin/:$PATH  # use clang, same as used for building Python 3.9
pip install -v .
cd ..

以上为：

llvmlite 在提交 334411cf638c8e06ba19bfda16b07dd64e9dac3c 和
numba 在提交 ca8132ba5e43fc3f79767046ed55217aeeabb35e 时。

Answer 6

根据https://askubuntu.com/questions/1286131/how-do-i-install-llvm-10-on-ubuntu-18-04 我在 Dockerfile 中添加了这些行

RUN apt-get -y install llvm-10*

RUN rm -f  /usr/bin/llvm-config

RUN ln -s /usr/bin/llvm-config-10 /usr/bin/llvm-config

它有效（安装了llvmlite）

Dockerfile因numba安装失败而出现llvm-config错误
