Step-by-Step Guide: How to Install PyTorch

Now, let’s dive into the installation process of PyTorch. There are multiple methods available, and we’ll cover the most common ones: using pip, conda, and installing from source.

1. Installation with pip

Installing PyTorch using pip is a straightforward process. Follow these steps:

  1. Ensure you have Python installed on your system. PyTorch is compatible with Python versions 3.6 and above.
  2. Open your command prompt or terminal and run the following command to install PyTorch:
    pip install torch torchvision
  3. Wait for the installation to complete. Once done, you’re all set to start using PyTorch!

2. Installation with conda

If you prefer using conda, follow these steps:

  1. Install Miniconda or Anaconda, which are package managers that simplify package installation and management.
  2. Open your command prompt or terminal and create a new conda environment:
    conda create -n myenv python=3.8
  3. Activate the newly created environment:
    conda activate myenv
  4. Install PyTorch and torchvision using the following conda command:
    conda install pytorch torchvision torchaudio cudatoolkit=11.1 -c pytorch -c conda-forge

3. Installation from source

For advanced users or those who require customization, installing PyTorch from source may be the preferred option. Here’s how you can do it:

  1. Ensure you have Git and CMake installed on your system.
  2. Clone the PyTorch repository from GitHub using the following command:
    git clone --recursive
  3. Navigate to the cloned repository and run the following commands to build and install PyTorch:
    cd pytorch
    python install
  4. Wait for the installation process to complete. Once finished, PyTorch will be ready to use.

Frequently Asked Questions (FAQ)
