Python - 安装sentencepiece异常

在安装transformers库时，sentencepiece无法安装，如下：

pip3 install --user transformers

解决问题参考：Pip install sentencepiece failure

在安装sentencepiece，无法进行，如下：

Building wheels for collected packages: sentencepieceBuilding wheel for sentencepiece (setup.py) ...

长时间等待，异常如下：

./build_bundled.sh:行15: cmake: 未找到命令make: *** 没有指明目标并且找不到 makefile。 停止。make: *** 没有规则可以创建目标“install”。 停止。Package sentencepiece was not found in the pkg-config search path.Perhaps you should add the directory containing `sentencepiece.pc'to the PKG_CONFIG_PATH environment variableNo package 'sentencepiece' foundFailed to find sentencepiece pkg-config----------------------------------------ERROR: Failed building wheel for sentencepiece

单独安装sentencepiece，也会出现异常。

pip3 install --user sentencepiece

下载sentencepiece的对应版本

sentencepiece

例如，CentOS 7对应的版本：

下载之后，安装

pip3 install --user sentencepiece-0.1.94-cp37-cp37m-manylinux2014_x86_64.whl

提示错误：平台版本不对，如下。

ERROR: sentencepiece-0.1.94-cp37-cp37m-manylinux2014_x86_64.whl is not a supported wheel on this platform. WARNING: You are using pip version 19.2.3, however version 20.2.4 is available. You should consider upgrading via the 'pip install --upgrade pip' command.

修改python库的命名方式，manylinux2014 ->linux， 即可：

mv sentencepiece-0.1.94-cp37-cp37m-manylinux2014_x86_64.whl sentencepiece-0.1.94-cp37-cp37m-linux_x86_64.whl

再次安装，即可：

pip3 install --user sentencepiece-0.1.94-cp37-cp37m-linux_x86_64.whl

最后安装transformers，即可

pip3 install --user transformers
