Install Caffe for Python: Step-by-Step Guide

Caffe is a popular deep learning framework. It is widely used for computer vision tasks. This guide will help you install Caffe for Python.

Prerequisites

Before installing Caffe, ensure you have the following:

• Python 3.6 or higher
• pip installed
• Basic knowledge of terminal commands

If you need help setting up Python, check our guide on Install Python Package on Raspberry Pi.

Step 1: Install Dependencies

Caffe requires several dependencies. Run the following commands in your terminal.

sudo apt-get update
sudo apt-get install -y libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler
sudo apt-get install -y --no-install-recommends libboost-all-dev

This installs essential libraries for Caffe. If you face issues, refer to Install and Set Up PyTables in Python.

Step 2: Clone Caffe Repository

Next, clone the Caffe repository from GitHub.

git clone https://github.com/BVLC/caffe.git
cd caffe

This downloads the latest Caffe source code.

Step 3: Install Python Requirements

Caffe has Python-specific dependencies. Install them using pip.

pip install -r python/requirements.txt

This ensures all Python dependencies are met.

Step 4: Configure and Build Caffe

Now, configure Caffe using CMake. Create a build directory first.

mkdir build
cd build
cmake ..

After configuration, build Caffe.

make all
make install

This compiles Caffe from source.

Step 5: Install Caffe Python Package

Finally, install the Caffe Python package.

make pycaffe

Add Caffe to your Python path.

export PYTHONPATH=/path/to/caffe/python:$PYTHONPATH

Replace /path/to/caffe with your Caffe directory.

Step 6: Verify Installation

Check if Caffe is installed correctly.

import caffe
print(caffe.__version__)

This should print the Caffe version.

Common Issues and Fixes

If you encounter errors, try these fixes:

• Ensure all dependencies are installed.
• Check Python path settings.
• Rebuild Caffe if changes are made.
