Mastering TensorFlow: A Comprehensive Guide to Installation and Troubleshooting

Python is a popular programming language widely used in the field of Artificial Intelligence (AI) and Machine Learning (ML). One of the most used libraries in AI and ML is TensorFlow.

TensorFlow is an open-source software library for dataflow programming used to create, train, and deploy ML models. However, sometimes installing and importing TensorFlow can be a daunting task.

This article will cover the steps to troubleshoot two common TensorFlow problems. The first is the “ModuleNotFoundError: No module named ‘tensorflow’,” and the second is “Import “tensorflow.keras” could not be resolved from source Pylance.”

Troubleshooting “ModuleNotFoundError: No module named ‘tensorflow'”

The TensorFlow package not found error occurs when Python does not find the TensorFlow package installed on the system.

Here are some reasons for this error:

  • TensorFlow package is not installed on the system;
  • Wrong version of Python is installed;
  • TensorFlow is not installed correctly;
  • The virtual environment set is not correct;
  • The IDE cannot find the TensorFlow package.

To install and import TensorFlow, follow these steps:

  1. Check your Python version.

    Before downloading TensorFlow, you need to make sure you have the correct Python version.

    TensorFlow requires Python 3.6-3.8, so you should download and install a compatible version of Python.

  2. Install TensorFlow using pip.

    Once you have installed the correct version of Python, you can install TensorFlow using pip.

    Open your command prompt and type the following command:

    pip install tensorflow

    This command will install the latest TensorFlow package available. If you want to install a specific version, you can use the following command instead:

    pip install tensorflow==

  3. Import TensorFlow in your Python code.

    Once you have installed TensorFlow, you can start using it in your Python code.

    Open your Python IDE and create a new project. Then, type the following code to import TensorFlow:

    import tensorflow as tf

    If you have installed TensorFlow correctly, this code will work, and you can start using TensorFlow in your project.

Troubleshooting “Import “tensorflow.keras” could not be resolved from source Pylance”

Another common problem that developers face is “Import “tensorflow.keras” could not be resolved from source Pylance”. This error occurs when the Python interpreter cannot find the TensorFlow package and its sub-packages.

Here are some reasons for this error:

  • The Python interpreter is not set up correctly;
  • The IDE is not pointing to the correct Python interpreter;
  • The paths are not set correctly;
  • The installation of TensorFlow is not correct.

To resolve this issue, follow these steps:

  1. Select the correct Python interpreter.

    You need to ensure that you have selected the correct path of the Python interpreter that has TensorFlow installed.

    If you have multiple Python interpreters installed on your system, you need to choose the correct one. To do this, open your IDE, go to the command palette, and select “Python: Select Interpreter.” Then choose the correct interpreter.

  2. Restart your IDE.

    After selecting the correct Python interpreter, restart your IDE. This step is essential to ensure that all the changes are applied correctly.

  3. Check TensorFlow installation location.

    Check the location where TensorFlow is installed. If you have installed TensorFlow in a virtual environment, you need to ensure that your IDE is pointing to that virtual environment.

    In VS Code, you can do this by opening the terminal and activating the virtual environment.

  4. Import tensorflow.keras in your code.

    After following the above steps, try importing tensorflow.keras in your code, and it should work without errors.
