Comparison of Conda and pip

Both Conda and pip are popular package managers for Python, each with its advantages and potential disadvantages.



  • Manages both Python packages and non-Python dependencies.

  • Simplifies package management by creating isolated environments.

  • Ensures consistent package versions across different environments.


  • Larger package sizes due to including dependencies.

  • Limited availability of some packages compared to pip.



  • Lightweight and straightforward package manager.

  • Provides access to a vast ecosystem of Python packages.


  • Does not handle non-Python dependencies.

  • May lead to dependency conflicts in complex environments.

Installing PyTorch via Conda

Conda is a popular package management system that simplifies the installation and management of software packages. Users can follow these steps to install PyTorch using Conda.

Step 1. Opening Terminal

The user should open the terminal on their Ubuntu 22.04 system. In Ubuntu, you can open the terminal using one of the following methods:

1. Using Keyboard Shortcut

  • Press Ctrl + Alt + T to quickly open a new terminal window.

2. Using Dash/Search

  • Press the Super/Windows key to open the Dash.
  • Type Terminal in the search bar.
  • Click on the Terminal icon that appears in the search results to open it.

3. Using Applications Menu

  • Click on the Applications menu located at the top left corner of the screen.
  • Navigate to Accessories or Utilities and find the Terminal application.
  • Click on Terminal to open it.

Step 2. Creating a New Conda Environment (Optional)

Creating a new environment is recommended to isolate PyTorch from other packages. The user can create a new environment with the following command:

conda create -n pytorch_env python=3.9

Step 3. Activating the Environment

Users should activate the newly created environment using the following command:

conda activate pytorch_env

Step 4. Installing PyTorch

Users should run the following command to install PyTorch with CUDA support:

conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch -c conda-forge

Installing PyTorch via pip

Pip is a package manager for Python packages. Although Conda is recommended for PyTorch installation, pip can also be used. Users can follow these steps.

Step 1. Ensuring Dependencies are Installed

Users should ensure that they have the necessary dependencies installed by running the following command:

sudo apt-get install libgl1-mesa-glx libegl1-mesa libxrandr2 libxrandr2 libxss1 libxcursor1 libxcomposite1 libasound2 libxi6 libxtst6

Step 2. Installing PyTorch

PyTorch can be installed with CUDA support using pip:

pip install torch torchvision torchaudio

Verifying PyTorch Installation

After installation, it's crucial to verify that PyTorch is correctly installed. Follow these steps.

Step 1. Launching Python Interpreter

Users should open the terminal and launch the Python interpreter by typing the following command:


Step 2. Importing PyTorch

Inside the Python interpreter, users can import PyTorch by using the following piece of code:

import torch

Step 3. Checking PyTorch Version

Users should check the PyTorch version to ensure the installation was successful by using the following code:




Readers can congratulate themselves for successfully installing PyTorch on Ubuntu 22.04 using either Conda or pip. Now they're ready to dive into the world of deep learning and build powerful machine learning models with PyTorch.
