python3.11.4和paddle2.5.1安装CPU版本-笔记
一、python3.11.4安装

下载地址：https://www.python.org/downloads/windows/
Python Releases for Windows
Latest Python 3 Release - Python 3.11.4

https://www.python.org/downloads/release/python-3114/

二、paddle2.5.1安装
CPU 版的 PaddlePaddle OK
python -m pip install paddlepaddle==2.5.1 -i https://mirror.baidu.com/pypi/simple

python -m pip install paddlepaddle==2.5.1 -i https://mirror.baidu.com/pypi/simple

以下是其他来源地址下载方式：
python -m pip install paddlepaddle==2.5.1 -i https://pypi.tuna.tsinghua.edu.cn/simple

ERROR: HTTP error 403 while getting https://pypi.tuna.tsinghua.edu.cn/packages/07
如果报上面的错误信息换成下面的地址下载和安装
python -m pip install paddlepaddle==2.5.1 -i https://pypi.douban.com/simple

需要先升级：
python.exe -m pip install --upgrade pip

python.exe -m pip install --upgrade pip

[notice] A new release of pip is available: 23.1.2 -> 23.2.1
[notice] To update, run: python.exe -m pip install --upgrade pip

升级pip为23.2.1版本的详细过程：

=====================================

E:\python311>python.exe -m pip install --upgrade pip

三、安装paddle环境测试代码：
python -c “import paddle; print(paddle.version)”

python -c "import paddle; print(paddle.__version__)"

报错问题如下所示：
ImportError: DLL load failed while importing libpaddle: 找不到指定的模块。

下载安装VC_redist.x64.exe
https://www.xitongzhijia.net/soft/225178.html
https://www.xitongzhijia.net/soft/225178.html
可解决上面的问题。

安装测试OK
E:\python311>python -c “import paddle; print(paddle.version)”
2.5.1

E:\python311>python -c "import paddle; print(paddle.__version__)"
2.5.1

四、vsCode环境安装扩展Python后测试文件：
testPaddleInstall.py

import paddle
paddle.utils.run_check()

import paddle
paddle.utils.run_check()

测试结果为:
PS F:\project\python\cwgis> & E:/python311/python.exe f:/project/python/cwgis/testPaddleInstall.py
Running verify PaddlePaddle program …
I0805 19:16:48.042397 12912 interpretercore.cc:237] New Executor is Running.
I0805 19:16:51.290495 12912 interpreter_util.cc:518] Standalone Executor is Used.
PaddlePaddle works well on 1 CPU.
PaddlePaddle is installed successfully! Let’s start deep learning with PaddlePaddle now.
