How to install Tensorflow on Python 2.7 on Windows?

Installing TensorFlow with Python 2.7 on Windows may present certain limitations, as TensorFlow officially discontinued support for Python 2.7 starting from version 1.6. The last version of TensorFlow that supports Python 2.7 is 1.5. Below are the steps to install TensorFlow 1.5 for Python 2.7 on Windows:

Step 1: Install Python 2.7

Ensure that Python 2.7 is installed on your system. You can download and install it from the Python official website.

Step 2: Configure Environment Variables

After installing Python, add the paths to Python and pip to your system's environment variables so that you can access them directly from the command line.

Step 3: Install TensorFlow

Since TensorFlow version 1.5 is the last version supporting Python 2.7, you must specify this version when installing using the pip command.

Open the command prompt and enter the following command:

bash
pip install tensorflow==1.5

This command downloads and installs TensorFlow version 1.5 from the Python Package Index.

Step 4: Verify Installation

After installation, verify that TensorFlow is correctly installed by running the following Python code:

python
import tensorflow as tf
print(tf.__version__)

If the output is 1.5.0, TensorFlow has been successfully installed.

Notes

• TensorFlow 1.5 may not support the latest features or security updates.
• For newer TensorFlow features, it is recommended to upgrade to Python 3.x and use the latest TensorFlow version.
• Ensure your Windows system has all necessary updates and drivers installed, particularly GPU drivers if you plan to use the GPU version of TensorFlow.
