安装 spacy 失败

Question

我有问题。 我正在尝试在我的 linux 机器上安装 spacy，但它给我这个命令带来了很多错误：

pip3 install spacy

这是我尝试安装它时得到的输出：

Command "/usr/bin/python3 -m pip install --ignore-installed --no-user --prefix /tmp/pip-build-env-srt_eep7 --no-warn-script-location --no-binary :none: --only-binary :none: -i https://pypi.org/simple --extra-index-url https://www.piwheels.org/simple -- setuptools wheel>0.32.0,<0.33.0 Cython cymem>=2.0.2,<2.1.0 preshed>=2.0.1,<2.1.0 murmurhash>=0.28.0,<1.1.0 thinc>=7.0.8,<7.1.0" failed with error code 1 in None

这是它给出的所有错误的相关输出。 我不知道该怎么做，但我需要它！？
我在带有 Raspbian buster lite 的 Raspberry Pi 3 上运行。

更新 现在我在下载源代码并将代码粘贴到 setup.py 中然后使用python /spacy/setup.py 运行它后收到此消息：

有什么建议吗？

Answer 1

因为你想在 Rasp 上编译 spacy。但 GCC 在 ARM 平台上不支持这些标志。

gcc：注意：有效参数是：armv2 armv2a armv3 armv3m armv4 armv4t armv5 armv5t armv5e armv5te armv5tej armv6 armv6j armv6k armv6z armv6kz armv6zk armv6t2 armv6-m armv6s-m armv7 armv7-a armv7ve armv7-r armv7-m armv7e-m armv8-a armv8.1-a armv8.2-a armv8.3-a armv8.4-a armv8-m.base armv8-m.main armv8-r iwmmxt iwmmxt2 本机 gcc：错误：缺少“-march =”的参数 gcc：错误：无法识别的命令行选项“-mavx2” gcc：错误：无法识别的命令行选项“-mfma” gcc：错误：无法识别的命令行选项“-mfpmath=sse”

因此，要使其在您的平台上运行，我建议您使用选项 --disable-sse2 运行配置。这意味着您可以下载spacy源代码，然后自己修改或配置其Makefile。然后试试python setup.py install。

您可能需要了解此setup.py 和Makefile

要更改setup.py 以适应您的平台，您可以修改some code，例如：

if is_new_osx():
    # On Mac, use libc++ because Apple deprecated use of
    # libstdc
    COMPILE_OPTIONS["other"].append("-stdlib=libc++")
    LINK_OPTIONS["other"].append("-lc++")
    # g++ (used by unix compiler on mac) links to libstdc++ as a default lib.
    # See: https://*.com/questions/1653047/avoid-linking-to-libstdc
    LINK_OPTIONS["other"].append("-nodefaultlibs")
    # Because I am running it on my Rasp Pi
    # I want to remove some options from LINK_OPTIONS or Add some into it
