    • Steps:
      1. Visit NVIDIA’s official website.
      2. Navigate to the CUDA Toolkit download section.
      3. Download the required version of the CUDA Toolkit.
      4. Install the Toolkit, ensuring to include all components.
      5. Download the compatible version of cuDNN.
      6. Extract and place cuDNN files in the CUDA directory.
      7. Add CUDA and cuDNN paths to system environment variables.

4. Check TensorFlow Installation

? Why it’s Crucial: The GPU-supported version of TensorFlow is optimized for graphics processing.

    • Steps:
      1. Open your Python environment or terminal.
      2. Uninstall current TensorFlow using the command: pip uninstall tensorflow
      3. Install the GPU-supported version: pip install tensorflow-gpu
      4. Restart your Python environment.
      5. Import TensorFlow and check its version to confirm installation.

5. Check for Missing Dependencies

? Why it Matters: Dependencies are foundational for TensorFlow’s GPU operations.

    • Steps:
      1. Ensure system environment variables include paths for CUDA and cuDNN.
      2. Update NVIDIA GPU drivers from NVIDIA’s website.
      3. Recheck TensorFlow’s GPU detection.

6. Verify Hardware Compatibility

? Why it’s Crucial: TensorFlow has set hardware requirements for GPU support.

    • Steps:
      1. Visit NVIDIA’s website.
      2. Navigate to the GPU compatibility section.
      3. Check your GPU’s compute capability.
      4. Ensure your GPU meets TensorFlow’s requirements.

7. Confirm TensorFlow GPU Utilization

? Why it Matters: Verifying GPU utilization ensures TensorFlow operates at peak efficiency.

    • Steps:
      1. Open your Python environment or terminal.
      2. Import TensorFlow using the command: import tensorflow as tf
      3. Run the command: tf.config.list_physical_devices('GPU')
      4. If the output lists your GPU, TensorFlow is utilizing it. If not, recheck previous steps and ensure all configurations are correct.
