前言

下载的Anaconda是Anaconda3-2024.02-1-Windows-x86_64版本

一、TensorFlow安装CPU版本

本例子，下载的python版本为3.11.7和tensorflow版本为2.16.1

1.新建虚拟环境

打开Anaconda Prompt，输入

conda create -n myenvname python=3.11.7

“myenvname”为自己的虚拟环境名字

2.激活虚拟环境

继续输入

activate myenvname

“myenvname”为自己的虚拟环境名字

3.下载tensorflow

直接安装tensorflow会遇到以下报错，这是提示有一些依赖没有安装

所以我先安装了依赖再下载tensorflow

pip install joblib==1.2.0 scipy==1.11.4 tabulate==0.9.0 tqdm==4.65.0 tensorflow==2.16.1 -i https://mirrors.aliyun.com/pypi/simple

4.验证是否下载成功

输入ipython，进入交互环境（要是报错，那可能是没有ipython，可以pip list查看一下，没有的话需要下载一个）

导入tensorflow

import tensorflow as tf

成功

二、TensorFlow安装GPU版本

本例子，下载的CUDA版本是11.5.2，cuDNN的版本是8.3.2，Python环境是3.9，tensorflow-gpu的版本是2.7.0。注：CUDA、cuDNN、python的环境要对应，不然会安装失败（很重要！！！）。

1.新建虚拟环境

打开Anaconda Prompt，输入

conda create -n myenvname python=3.9

“myenvname”为自己的虚拟环境名字

2.激活虚拟环境

activate myenvname

“myenvname”为自己的虚拟环境名字

3.安装tensorflow-gpu

pip install tensorflow-gpu==2.7.0 -i https://pypi.tuna.tsinghua.edu.cn/simple

4.验证是否下载成功

进入py编程thon环境，导入tensorflow

 import tensorflow as tf

要是遇到这个问题，提示protobuf版本过低

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROandroidTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

输入exit()退出python环境，回到虚拟环境

pip install protobuf==3.19.6 -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn

再次进入python环境，输入“import tensorflow as tf”，要是遇到如下问题，提示TensorFlow与NumPy的版本不兼容

>>> import tensorflow as tf

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.0 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

输入exit()退出python环境，回到虚拟环境

pip install numpy==1.21.6 -i https://pypi.tuna.tsinghua.edu.cn/simple/

进入python环境，输入

import tensorflow as tf
tf.__version__
tf.test.is_gpu_available()

查看版本2.7.0，版本正确。末尾显示True，TensorFlow检测到可用的GPU，安装成功，exit()退出python环境

后续我想用ipython查看是否安装成功，出现以下问题进入ipython环境，输入

import tensorflow as tf
tf.__version__
tf.test.is_gpu_available()

创建虚拟环境的时候指定python版本为3.9，但是这里却显示3.11.7。

末尾显示False，TensorFlow没有检测到可用的GPU。

猜测可能是这个虚拟环境没有ipython，可能用了其他环境的ipython。

解决方案，可以在虚拟环境中用pip list查看虚拟环境中是否有ipython，要是没有，需要安装一个，然后就可以解决了
