In the absence of an external network, the Python environment can only be installed offline.
Install Python offline on Windows
Download address of Python offline installation package: https://www.python.org/ftp/python/
What I chose is:python-3.8.5-amd64.exe
Double-click to run the installation package to complete the installation.
After the installation is complete, add environment variables:
D:\Python3.8.5\
D:\Python3.8.5\Scripts\
Check whether it is successful:
python --version
Outputting the version number Python 3.8.5indicates successful installation.
If the output version number is incorrect, try changing the command python3 --version.
Install Python offline on Linux
Download address of Python offline installation package: https://www.python.org/ftp/python/
What I chose is:Python-3.8.5.tgz
Enter the decompression path:
cd /home/root/Download/Python-3.8.5
Set installation path:
./configure --prefix=/usr/local/python3 --enable-shared
make && make install
Establish a soft connection between python and pip:
ln -s /usr/local/python3/bin/python3.8 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3.8 /usr/bin/pip3
Configure python3's lib to ldconfig:
echo "/usr/local/python3/lib" > /etc/ld.so.conf.d/python3.8.conf
ldconfig
Check whether Python is installed successfully:
python3 --version
Outputting the version number Python 3.8.5indicates successful installation.
Check whether pip is configured successfully:
pip3 --version
The following output indicates success:
pip 20.2.4 from /usr/local/python3/lib/python3.8/site-packages/pip (python 3.8)
Install Python on Ubuntu
The way Ubuntu installs Python is different from other Linux systems.
If there is a network connection, you can directly use the command line to install:
sudo apt-get install python3.8
sudo apt install python3-pip
If there is no Internet, you need to download the offline package first.
Download address of Python offline installation package: https://www.python.org/ftp/python/
What I chose is:Python-3.8.5.tgz
Unzip and enter the installation directory:
sudo tar -zxvf Python-3.8.5.tgz -C ~
cd Python-3.8.5
Install the compilation environment:
sudo apt-get install zlib1g-dev libbz2-dev libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev tk-dev libgdbm-dev libdb-dev libpcap-dev xz-utils libexpat1-dev liblzma-dev libffi-dev libc6-dev
If there is a network, sudo apt-getyou can use it directly. When offline, you need to download the above installation package and copy it in before installing it.
Initialize and specify path:
sudo ./configure --prefix=/usr/local/python3
Compile:
sudo make
test:
sudo make test
Install:
sudo make install
Add environment variables:
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
Create a soft link:
ln -s /usr/local/python3/bin/python3.8 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3.8 /usr/bin/pip3
Check whether Python is installed successfully:
python3 --version
Outputting the version number Python 3.8.5indicates successful installation.

Winodws offline installation of pip package
First create a new file requirements.txtand write the package that needs to be downloaded. For example:
transformers==4.27.1
torch>=1.10
pandas
numpy
Packages being downloaded requirements.txt:
pip3 download -d D:\Download\package -r requirements.txt
Download a single package (taking numpy as an example):
pip3 download -d D:\Download\package numpy
Offline installation of downloaded packages:
pip3 install --no-index --find-links=D:\Download\package -r requirements.txt
Install a single package offline (taking numpy as an example):
pip3 install --no-index --find-links=D:\Download\package numpy
Linux offline installation pip package
