Linux Python3.6.8离线安装Pytorch1.10
Linux Python3.6.8离线安装Pytorch1.10
目录
一、Linux安装编译依赖
1、Linux安装GCC编译器
Linux离线编译编译Python需要gcc编译器编译，如果没有安装直接编译会出现以下错误
configure: error: no acceptable C compiler found in $PATH
yum -y install gcc2、Linux安装Make工具
Linux离线编译编译Python需要Make工具安装，如果没有安装直接编译会出现以下错误
-bash: make: command not found
yum -y install make3、Linux安装OpenSSL依赖
pytorch 需要依赖OpenSSL模块，如果没有OpenSSL依赖，直接安装会出现以下错误
Can't connect to HTTPS URL because the SSL module is not available
验证OpenSSL模块
openssl versionyum安装OpenSSL
yum -y install openssl openssl-develrpm查看OpenSSL模块
rpm -q openssl
rpm -q openssl-devel二、Linux安装python3.6.8
1、Python3.6.8下载
Python官方网站：Welcome to Python.org
Python历史版本：Index of /ftp/python/
Python3.6.8下载：https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz
2、Python3.6.8编译安装
yum -y install zlib*tar zxvf Python-3.6.8.tgz -C /usr/local/cd /usr/local/Python-3.6.8 && make distcleanpython3.6.6以下需要加 --with-ssl 参数，python3.6.8可加可不加，加了无伤大雅不影响编译安装
./configure --prefix=/usr/local/python3.6.8 --with-ssl --enable-optimizationsmake && make install提示以下信息则表示编译成功
Collecting setuptools Collecting pip Installing collected packages: setuptools, pip Successfully installed pip-18.1 setuptools-40.6.2
3、环境变量配置
创建软连接
ln -s /usr/local/python3.6.8 /usr/local/python3
ln -s /usr/local/python3/bin/python3 /usr/bin/python3配置环境变量
echo '
# python3 config
export PYTHON3_HOME=/usr/local/python3
export PATH=$PATH:$PYTHON3_HOME/bin' >> /etc/profilesource /etc/profile
tail -n 6 /etc/profile4、验证Python环境
测试python安装
python -V
python3 -V更新 pip 模块
pip3 install --upgrade pip查看已安装模块
pip3 list
三、pip3 离线安装依赖库和pytorch
1、离线下载依赖库
功能 | 模块 | 官方地址 | 安装包链接 |
|---|---|---|---|
numpy | numpy | numpy · PyPI | numpy-1.19.5-cp36-cp36m-manylinux2010_x86_64.whl |
Pillow | PIL | Pillow · PyPI | Pillow-8.4.0-cp36-cp36m-manylinux_2_17_x86_64.manylinux2014_x86_64.whl |
typing_extensions | typing_extensions | typing-extensions · PyPI | typing_extensions-4.0.1-py3-none-any.whl |
dataclasses | dataclasses | dataclasses · PyPI | dataclasses-0.8-py3-none-any.whl |
torchaudio | torchaudio | torchaudio · PyPI | torchaudio-0.10.1-cp36-cp36m-manylinux1_x86_64.whl |
torchvision | torchvision | torchvision · PyPI | torchvision-0.11.2-cp36-cp36m-manylinux1_x86_64.whl |
torch | torch | torch · PyPI | torch-1.10.1-cp36-cp36m-manylinux1_x86_64.whl |
2、离线安装依赖库和pytorch
pip3 install numpy-1.19.5-cp36-cp36m-manylinux2010_x86_64.whl
pip3 install Pillow-8.4.0-cp36-cp36m-manylinux_2_17_x86_64.manylinux2014_x86_64.whl
pip3 install typing_extensions-4.0.1-py3-none-any.whl
pip3 install dataclasses-0.8-py3-none-any.whl
pip3 install torch-1.10.1-cp36-cp36m-manylinux1_x86_64.whl
pip3 install torchaudio-0.10.1-cp36-cp36m-manylinux1_x86_64.whl
pip3 install torchvision-0.11.2-cp36-cp36m-manylinux1_x86_64.whl3、在线安装pytorch
pip3 install torch==1.10.1+cpu torchvision==0.11.2+cpu torchaudio==0.10.1+cpu -f https://download.pytorch.org/whl/cpu/torch_stable.html四、常见依赖问题解决
1、_bz2模块依赖问题
pytorch 需要依赖bz2模块，如果没有bz2依赖，在导入torchvision 模块时会出现以下错误
from _bz2 import BZ2Compressor, BZ2Decompressor ModuleNotFoundError: No module named '_bz2'
yum 安装 bz2 依赖
yum -y install bzip2 bzip2下载 bz2 依赖：_bz2.cpython-36m-x86_64-linux-gnu.so
wget https://gitee.com/AlEinstein/utils/raw/master/linux/python/_bz2.cpython-36m-x86_64-linux-gnu.socp _bz2.cpython-36m-x86_64-linux-gnu.so /usr/local/python3/lib/python3.6/lib-dynload/python3from _bz2 import BZ2Compressor, BZ2Decompressor2、_lzma 模块依赖问题
File "/usr/local/python3/lib/python3.6/lzma.py", line 27, in <module> from _lzma import * ModuleNotFoundError: No module named '_lzma'
Linux 和 Python安装 lzma 依赖
yum -y install xz-devel python-backports-lzmapip3 install backports.lzma修改 lzma.py 模块文件内容（在27、28行）
cp /usr/local/python3/lib/python3.6/lzma.py /usr/local/python3/lib/python3.6/lzma.py.initvim /usr/local/python3/lib/python3.6/lzma.pytry:
from _lzma import *
from _lzma import _encode_filter_properties, _decode_filter_properties
except ImportError:
from backports.lzma import *
from backports.lzma import _encode_filter_properties, _decode_filter_properties
