pip安裝python三方庫

發布時間:2023-03-10 06:12:18

『壹』 python第三方庫如何安裝

1、在cmd命令行直接使用pip install 包名命令安裝
示例:

注意:安裝成功會顯示Successfully installed keras,如果出現黃色字體警告,是由於pip庫包不是最新的,但keras庫已成功安裝,可隨後對pip包進行更新,更新命令:python -m pip install --upgrade pip。
2、手動下載第三方庫,然後在cmd命令行使用pip install 下載文件名命令安裝下載的第三方庫(https://www.lfd.uci.e/~gohlke/pythonlibs/)

『貳』 python用了第三方庫怎麼在其他地方用

python用了第三方庫在其他地方用的方法是採用pip工具安裝。因為python自帶了包管理器,在使用第三方庫之後在別的地方可以使用pip命令自動安裝,然後就可以在別的地方也使用這些第三方庫了。

『肆』 python 第三方庫怎麼安裝

【方法一】: 通過setuptools來安裝python模塊
首先下載
NOTE: 最好下載個setuptools,本人是15.2版本,裡麵包含了ez_setup
運行 python ez_setup.py
D:\work\installation\setuptools-15.2\setuptools-15.2>python ez_setup.py > 1.txt
Extracting in c:\users\admini~1\appdata\local\temp\tmpbxikxf
Now working in c:\users\admini~1\appdata\local\temp\tmpbxikxf\setuptools-15.2
Installing Setuptools
......
Copying setuptools-15.2-py2.7.egg to c:\python27\lib\site-packages
setuptools 15.2 is already the active version in easy-install.pth
Installing easy_install-script.py script to C:\Python27\Scripts
Installing easy_install.exe script to C:\Python27\Scripts

【方法二】: 通過pip來安裝python模塊
安裝 easy_install pip
D:\work>easy_install pip
Searching for pip
Best match: pip 6.1.1
Processing pip-6.1.1-py2.7.egg
pip 6.1.1 is already the active version in easy-install.pth
Installing pip-script.py script to C:\Python27\Scripts
Installing pip.exe script to C:\Python27\Scripts
Installing pip2.7-script.py script to C:\Python27\Scripts
Installing pip2.7.exe script to C:\Python27\Scripts
Installing pip2-script.py script to C:\Python27\Scripts
Installing pip2.exe script to C:\Python27\Scripts

Using c:\python27\lib\site-packages\pip-6.1.1-py2.7.egg
