Install Multiple Version of Tensorflow Into Python Virtual Environment

You can use multiple version of tensorflow by creating python virtual environment.
"venv" module of python is used to create and manage virtual environments.

How to create python virtual environment:

• Install the python3-venv module

sudo apt-get update 

sudo apt-get install python3-venv

• Go to the directory, where you want to create virtual environment.
• Type following code to create virtual environment

python3 -m venv environment_name

• Activate the virtual environment

source environment_name/bin/activate

Congratulations!!! You have created and activated your virtual environments.

Installing Tensorflow into virtual environment:

• Upgrade your pip command using following code

pip install --upgrade pip

• Install specific version of tensorflow you want

pip install tensorflow==1.13.1

Check, if tensorflow is successfully installed or not:

• Create a file named "welcome.py"

gedit welcome.py

• Write the following code into it and save it.

import tensorflow as tf
welcome = tf.constant('Welcome to python virtual environment!')
sess = tf.Session()
print(sess.run(welcome))

• Run the file

python welcome.py

If it shows the output "Welcome to python virtual environment!", then tensorflow is installed successfully.

Congratulations!!! You have successfully installed tensorflow into virtual environment!

Running code:

To run code create python file with '.py' extension and run it from the virtual environment with the python following the 'program_name.py'.
