No Module Named ‘TensorFlow’

TensorFlow is a free and open-source library for machine learning and artificial intelligence. It offers a vast collection of tools and utilities that makes the process of machine learning and AI more intuitive and fun.

TensorFlow is cross-platform and can be installed on any machine running Linux, macOS, Linux, Android, or a JavaScript engine.

In some instances, you may face a “No Module Named TensorFlow” error when attempting to use TensorFlow in your application.

Throughout this guide, we will explore various scenarios of why this error occurs and how you can resolve it.

What is the No Module Named TensorFlow Error?

The No module named error in Python occurs when you attempt to import a module that does not exist in that environment.

For example, if you attempt to import the TensorFlow module in a newly initialized Python environment, the interpreter will return the No Module Named TensorFlow error.

For example, start by creating a simple virtual environment with venv.

$ python -m venv sample_env
$ sample_env\Scripts\activate

In the new environment, launch the Python interpreter and import TensorFlow.

$ python
>>> import tensorflow

Since we are in a new environment and do not have the TensorFlow package installed, the import statement will fail with a ModuleNotFoundError.

A solution to Fix the No Module Named Tensorflow

If you are getting a module not found error due to a missing TensorFlow package, you can resolve it by installing the TensorFlow package.

Installing TensorFlow via Pip

In Python, we install and manage packages using pip. It is installed by default. Hence, you can run the pip install command followed by the package’s name to install.

The command to install TensorFlow with pip.

$ pip install tensorflow

The command above will download and install the current stable release of the TensorFlow package.

Once the installation is complete, verify TensorFlow has been installed successfully by running the command:

$ pip show tensorflow

The command should return details about the installed tensorflow package.

Now, launch the Python interactive shell and import TensorFlow

>>> import tensorflow as tf

You should now have the “no module named TensorFlow” error resolved.

Install TensorFlow via Conda (Spyder, Jupyter, Virtual Environments).

Using Anaconda or Miniconda as your Python interpreter, you can install TensorFlow using conda.

Run the command:

$ conda install -c conda-forge tensorflow

The command invokes the conda package manager and tells it to install the TensorFlow package from the conda-forge repository.

Installing TensorFlow on Linux

On Linux, you can use pip3 to install the TensorFlow package using the command:

$ sudo pip3 install tensorflow

The command should invoke pip3 and install the TensorFlow package on your system.

TensorFlow Dependencies

In some instances, TensorFlow import may fail if you do not have the add-ons package installed.

The TensorFlow add-ons package comes with a collection of useful TensorFlow APIs that extend the core functionality of the base TensorFlow package.

You can install the TensorFlow addons with pip using the command:

$ pip install tensorflow-addons

On Linux, use sudo:

$ sudo pip3 install tensorflow-addons

For conda users, run:

$ conda install -c esri tensorflow-addons
$ sudo conda install -c esri tensorflow-addons

Re-Install TensorFlow

If you face the No Module named TensorFlow error but you are certain that you have the package installed, you can re-install it without deleting your Python environment using the –ignore-installed flag.

$ pip install tensorflow --ignore-installed
$ sudo pip3 install tensorflow --ignore-installed

Install TensorFlow as a Normal User

Python may fail to import the TensorFlow package due to permissions. However, you can install TensorFlow as the normal user using the –user flag in such a scenario.

$ pip install tensorflow --user
$ sudo pip3 install tensorflow --user

Incorrect Python Version

The TensorFlow package cannot be installed on 32-bit versions of the Python language.

If you are facing install issues with 32-bit language, uninstall Python and download the 64-bit version.

Verify TensorFlow Packages

TensorFlow depends on other scientific packages such as NumPy, Pandas, and etc. Before installing TensorFlow, ensure you have its requirements met.

To view the list of installed Python packages, run the pip list command:

$ pip list

Install CUDA Toolkit

If you wish to run TensorFlow on a GPU, you will need to install the CUDA Toolkit on your system.

Navigate to the resource below and download the latest version of the CUDA toolkit for your system.

https://developer.nvidia.com/cuda-toolkit-archive

NOTE that the CUDA Toolkit is only available for Windows and Linux systems.

If you are looking to use TensorFlow for Deep Neural Network on your GPU, install the cuDNN Toolkit.

The resource is provided in the link below:

https://developer.nvidia.com/cudnn

Once completed, install the cuda and cudnn packages with conda as:

$ conda install -c conda-forge cudatoolkit=11.2 cudnn=8.1.0

Windows Install Microsoft Visual C++ Redist

On Windows, you need to install the Visual C++ Redistributable runtime libraries. These are required for TensorFlow and GPU operations.

You can download and install these packages from the link below:

https://docs.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170
