Pre-Installation System Setup

System Update and Package Management

Start by updating your Fedora 42 system to the latest packages. Open a terminal and execute the following commands:

sudo dnf update -y
sudo dnf install -y python3-pip python3-devel
sudo dnf groupinstall -y "Development Tools"

These commands ensure your system has the latest security patches and essential development components. The Development Tools group includes GCC, make, and other compilation utilities required for building Python packages with native extensions.

Install additional dependencies that TensorFlow may require:

sudo dnf install -y python3-virtualenv git wget curl
sudo dnf install -y libffi-devel openssl-devel

Development Environment Preparation

Creating isolated Python environments prevents package conflicts and maintains system stability. Virtual environments ensure TensorFlow installations don’t interfere with system Python packages or other projects.

Install virtualenv and pip tools:

python3 -m pip install --user --upgrade pip
python3 -m pip install --user virtualenv

Set up environment variables by adding the following to your ~/.bashrc file:

export PATH=$HOME/.local/bin:$PATH
export PYTHONPATH=$HOME/.local/lib/python3.11/site-packages:$PYTHONPATH

Reload your shell configuration:

source ~/.bashrc

Method 1: Installing TensorFlow via Pip

CPU-Only Installation

The pip installation method offers the simplest approach for most users. Create a dedicated virtual environment for TensorFlow:

python3 -m virtualenv tensorflow-env
source tensorflow-env/bin/activate

Your terminal prompt should now display (tensorflow-env) indicating the active environment. Upgrade pip to the latest version to avoid compatibility issues:

pip install --upgrade pip

Install TensorFlow CPU version:

pip install tensorflow

This command downloads and installs the latest stable TensorFlow release optimized for CPU computation. The installation includes all necessary dependencies and should complete within a few minutes, depending on your internet connection.

Verify the installation by launching Python and importing TensorFlow:

python3 -c "import tensorflow as tf; print(tf.__version__)"

You should see the TensorFlow version number displayed without any error messages. Test basic functionality:

python3 -c "import tensorflow as tf; print(tf.reduce_sum(tf.random.normal([1000, 1000])))"

GPU-Enabled Installation

GPU acceleration significantly improves TensorFlow performance for training deep neural networks. First, install NVIDIA drivers compatible with your graphics card:

sudo dnf install -y akmod-nvidia xorg-x11-drv-nvidia-cuda

Reboot your system to load the new drivers:

sudo reboot

After rebooting, verify driver installation:

nvidia-smi

This command should display your GPU information and current driver version. If unsuccessful, troubleshoot driver installation before proceeding.

Install CUDA Toolkit 12.3:

sudo dnf config-manager --add-repo https://developer.download.nvidia.com/compute/cuda/repos/fedora37/x86_64/cuda-fedora37.repo
sudo dnf install -y cuda-toolkit-12-3

Set up CUDA environment variables:

echo 'export PATH=/usr/local/cuda-12.3/bin:$PATH' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH=/usr/local/cuda-12.3/lib64:$LD_LIBRARY_PATH' >> ~/.bashrc
source ~/.bashrc

Install TensorFlow with GPU support in your virtual environment:

source tensorflow-env/bin/activate
pip install tensorflow[and-cuda]

Test GPU detection:

python3 -c "import tensorflow as tf; print('GPU Available:', tf.config.list_physical_devices('GPU'))"

Method 2: Installing TensorFlow via Conda

Anaconda/Miniconda Setup

Conda provides excellent package management for scientific computing environments. Download Miniconda for Linux:

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh

conda create -n tensorflow-conda python=3.11
conda activate tensorflow-conda

TensorFlow Installation through Conda

Install TensorFlow using conda-forge channel for the most up-to-date packages:

conda install -c conda-forge tensorflow

For GPU support with conda:

conda install -c conda-forge tensorflow-gpu cudatoolkit cudnn

Conda automatically manages CUDA and cuDNN dependencies, simplifying GPU setup compared to pip installations. Verify the installation:

python -c "import tensorflow as tf; print(tf.__version__)"

Test GPU functionality if applicable:

python -c "import tensorflow as tf; print(tf.config.list_physical_devices())"

Method 3: Building TensorFlow from Source

Source Compilation Prerequisites

Building TensorFlow from source enables custom optimizations for your specific hardware configuration. Install Bazel build system:

sudo dnf install -y java-11-openjdk-devel
wget https://github.com/bazelbuild/bazel/releases/download/8.2.1/bazel-8.2.1-installer-linux-x86_64.sh
chmod +x bazel-8.2.1-installer-linux-x86_64.sh
./bazel-8.2.1-installer-linux-x86_64.sh --user

Add Bazel to your PATH:

echo 'export PATH=$HOME/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

Clone TensorFlow repository:

git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow
git checkout v2.15.0

Install Python dependencies for building:

pip install numpy wheel packaging requests opt_einsum
pip install keras_preprocessing --no-deps

CPU Build Process

Configure TensorFlow build settings:

python3 configure.py

Answer the configuration prompts based on your requirements. For a CPU-only build, decline CUDA support when prompted. Enable optimizations for your specific CPU architecture when asked.

Build TensorFlow using Bazel:

bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package

This compilation process may take 1-3 hours depending on your hardware. The build utilizes all available CPU cores for maximum efficiency.

Create the wheel package:

./bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg

Install the compiled TensorFlow:

pip install /tmp/tensorflow_pkg/tensorflow-*.whl

GPU Build Process

For GPU builds, ensure CUDA and cuDNN are properly installed before configuration. Run the configure script and enable CUDA support:

python3 configure.py

When prompted for CUDA support, answer yes and provide the correct paths:

  • CUDA toolkit location: /usr/local/cuda-12.3
  • cuDNN location: /usr/local/cuda-12.3

Build with GPU support:

bazel build --config=opt --config=cuda //tensorflow/tools/pip_package:build_pip_package

GPU builds require additional compilation time due to CUDA kernel generation. Expect 2-4 hours for complete compilation on modern hardware.

source ~/.bashrc

Installation Verification and Testing

Basic TensorFlow Functionality Tests

Verify TensorFlow installation with comprehensive tests. Check version and build information:

import tensorflow as tf
print("TensorFlow version:", tf.__version__)
print("Built with CUDA:", tf.test.is_built_with_cuda())
print("Available devices:", tf.config.list_physical_devices())

Test basic tensor operations:

import tensorflow as tf

# Create tensors
a = tf.constant([[1, 2], [3, 4]])
b = tf.constant([[5, 6], [7, 8]])

# Perform operations
c = tf.matmul(a, b)
print("Matrix multiplication result:")
print(c.numpy())

GPU Functionality Verification

For GPU installations, verify proper detection and functionality:

import tensorflow as tf

# Check GPU availability
gpus = tf.config.list_physical_devices('GPU')
if gpus:
    print(f"Found {len(gpus)} GPU(s)")
    for gpu in gpus:
        print(f"GPU: {gpu}")
        
    # Test GPU computation
    with tf.device('/GPU:0'):
        a = tf.random.normal([10000, 10000])
        b = tf.random.normal([10000, 10000])
        c = tf.matmul(a, b)
        print("GPU computation successful")
else:
    print("No GPUs found")

Monitor GPU utilization during computation:

watch -n 1 nvidia-smi

Troubleshooting Common Issues

Installation Problems

Package conflicts often occur when mixing installation methods. If encountering dependency issues, create a fresh virtual environment:

rm -rf tensorflow-env
python3 -m virtualenv tensorflow-env
source tensorflow-env/bin/activate

For source compilation errors, ensure sufficient disk space and memory. Bazel builds require substantial resources and may fail on systems with limited RAM.

Python version mismatches cause import failures. Verify compatibility:

python3 --version
pip list | grep tensorflow

Runtime and GPU Issues

CUDA version mismatches prevent GPU utilization. Check compatibility between TensorFlow, CUDA, and cuDNN versions. The TensorFlow documentation provides a compatibility matrix for reference.

GPU memory errors indicate insufficient VRAM or improper memory management. Configure GPU memory growth:

import tensorflow as tf

gpus = tf.config.experimental.list_physical_devices('GPU')
if gpus:
    tf.config.experimental.set_memory_growth(gpus[0], True)

Driver conflicts may require complete cleanup and reinstallation. Use DDU (Display Driver Uninstaller) equivalents for Linux or manual removal of driver files.

Best Practices and Optimization

Environment Management

Maintain separate environments for different projects to prevent version conflicts. Use descriptive names for virtual environments:

python3 -m virtualenv ml-project-2024
python3 -m virtualenv research-env

Document environment requirements in requirements.txt files:

pip freeze > requirements.txt

Backup and restore environments using conda or pip:

conda env export > environment.yml
conda env create -f environment.yml

Performance Optimization

Enable mixed precision training for improved GPU performance:

import tensorflow as tf

policy = tf.keras.mixed_precision.Policy('mixed_float16')
tf.keras.mixed_precision.set_global_policy(policy)

Configure TensorFlow for optimal CPU performance:

import tensorflow as tf

tf.config.threading.set_inter_op_parallelism_threads(0)
tf.config.threading.set_intra_op_parallelism_threads(0)

Monitor resource utilization during training to identify bottlenecks and optimize accordingly.
