Linux & Windows TensorFlow 1.14 升级 2.2

本文最后更新于：2024年5月7日下午

准备尝试升级TensorFlow 1.14 到2.2，需要同时升级本地和服务器的环境，本文记录主要过程。

环境需求

当前TensorFlow最高版本 2.2.+ ，需要CUDA 10.1，cudnn 7.6

官网下载：https://developer.nvidia.com/

显卡驱动需要满足CUDA版本要求

CUDA与显卡驱动：https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html

TensorFlow-GPU与CUDA cudnn Python版本关系：https://tensorflow.google.cn/install/source_windows?hl=en#gpu

Linux

下载 cuda_10.1.243_418.87.00_linux.run 并安装（之前装过并运行过TensorFlow，相关库不过时的话可以不特意去装 cudnn）

过程中不需要安装驱动

将 /usr/local/cuda 软链接指向 cuda-10.1

在 ~/.bashrc 中添加环境变量：

1
2
3

export PATH="$PATH:/usr/local/cuda/bin"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64/"
export LIBRARY_PATH="$LIBRARY_PATH:/usr/local/cuda/lib64"

下载 TensorFlow ：tensorflow_gpu-2.2.0-cp37-cp37m-manylinux2010_x86_64.whl

或使用pip安装

1	`pip install tensorflow-gpu`

会自动安装最新版 2.2.0 版本tf

Windows

下载 cuda_10.1.243_426.00_win10.exe 并安装（之前装过并运行过TensorFlow，相关库不过时的话可以不特意去装 cudnn）

我之前安装了CUDA10.0，不需要卸载原始版本，直接使用默认配置安装新版CUDA即可

下载 TensorFlow ：tensorflow_gpu-2.2.0-cp37-cp37m-win_amd64.whl

或使用pip安装

1	`pip install tensorflow-gpu`

会自动安装最新版 2.2.0 版本tf

测试

python 环境下测试

>>> import tensorflow as tf
>>> tf.__version__
'2.2.0'
>>> tf.test.is_gpu_available()
WARNING:tensorflow:From <stdin>:1: is_gpu_available (from tensorflow.python.framework.test_util) is deprecated and will be removed in a future version.
Instructions for updating:
Use `tf.config.list_physical_devices('GPU')` instead.
