很多小伙伴在使用jieba的paddle模式时遇到一个问题,那就是paddlepaddle-tiny安装不上,执行
pip install paddlepaddle-tiny==1.6.1
会出现以下错误:
ERROR: Could not find a version that satisfies the requirement paddlepaddle-tiny==1.6.1 (from versions: none)
ERROR: No matching distribution found for paddlepaddle-tiny==1.6.1
我也遇到了这个莫名其妙的错误,竟然找不到
paddlepaddle-tiny==1.6.1
?
(行文杂乱,解决方法直接看最后)
大名鼎鼎的paddlepaddle不会没有官方镜像吧,pypi上确实有,但是最新的版本还有2019年的:
可以看到,最新版本名字为paddlepaddle_tiny-1.6.1-cp37-cp37m-win_amd64.whl
那就还是轮子(wheel)不匹配的问题,通过
pip debug --verbose
命令可以查看当前操作系统支持的标签,如下所示:
Compatible tags: 33
cp39-cp39-win_amd64
cp39-abi3-win_amd64
cp39-none-win_amd64
cp38-abi3-win_amd64

cp36-abi3-win_amd64

py33-none-win_amd64
py32-none-win_amd64

py36-none-any
py35-none-any
py34-none-any
py33-none-any
py32-none-any
py31-none-any
py30-none-any
通过更改文件名的方式可以强制安装wheel,那么问题来了,我怎么才能知道这个wheel和我的环境到底匹不匹配呢?
轮子(wheel)是通过
build
包构建打包生成的,那么这个wheel的文件名规则自然也在build包中,源码看不懂,但总可以在文档中发现蛛丝马迹(以下是pip的文档,链接pip_debug):
platform和python_version都好理解,那implementation又是什么,‘pp’、‘jy’、‘cp’、'ip’都是啥意思?
通过搜索引擎加文档,找到了答案,可以在本机上通过以下方式查看自己的python实现:
最后还剩下一个abi,api是python的接口,abi是c的接口,简单理解为c语言的接口吧,个人理解,感觉应该影响不大,应该从tag上看好多abi都是none,这意思应该是兼容吧?
解决
将文件名字改为paddlepaddle_tiny-1.6.1-cp37-abi3-win_amd64.whl(随便改一个abi,或者改为none),执行命令
pip install paddlepaddle_tiny-1.6.1-cp37-abi3-win_amd64.whl
,安装成功!

但是paddle模式还是不能正常运行,根据我的尝试,还需要安装paddlepaddle,并调整protobuf的版本,我用的版本是:
paddlepaddle==2.3.2
protobuf==3.20.0
还要加上:
paddle.enable_static()
最后paddle模式成功运行!
