如何在Amazon Linux2 m6g实例中安装pyarrow

Question

我正在尝试在拥有ARM架构的Amazon Linux2 m6g实例中安装pyarrow。我已经安装了几个依赖项，现在在运行pip3.8 install pyarrow时被这个错误卡住了

-- Found the Arrow core static library: /usr/lib64/libarrow.a
    -- Could NOT find ArrowPython (missing: ArrowPython_DIR)
    -- Checking for module 'arrow-python'
    --   No package 'arrow-python' found
    CMake Error at /usr/local/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:165 (message):
      Could NOT find ArrowPython (missing: ARROW_PYTHON_INCLUDE_DIR
      ARROW_PYTHON_LIB_DIR) (found version "2.0.0")
    Call Stack (most recent call first):
      /usr/local/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:458 (_FPHSA_FAILURE_MESSAGE)
      cmake_modules/FindArrowPython.cmake:76 (find_package_handle_standard_args)
      CMakeLists.txt:215 (find_package)

它说我需要安装ArrowPython包。当我运行sudo yum install arrow-python-libs来安装这个包时，我得到了这个错误：

Error: Package: openblas-threads-0.3.3-2.el7.aarch64 (epel)
           Requires: libgfortran.so.3()(64bit)

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我也尝试过其他pyarrow版本，但我得到了相同的错误。

我该如何解决这个问题呢？

Answer 1

我无法通过conda安装。或者当我尝试import pyarrow时，conda one出现了导入错误。但还是让它工作了。安装conda后，请通过以下方式：

pip install pyarrow=2
