Python pip install psutil

How to Solve Python ModuleNotFoundError: no module named ‘psutil’

You can install psutil in Python 3 with python3 -m pip install psutil .

Or conda install -c conda-forge psutil for conda environments.

This tutorial goes through the exact steps to troubleshoot this error for the Windows, Mac and Linux operating systems.

What is ModuleNotFoundError?

The ModuleNotFoundError occurs when the module you want to use is not present in your Python environment. There are several causes of the modulenotfounderror:

The module’s name is incorrect, in which case you have to check the name of the module you tried to import. Let’s try to import the re module with a double e to see what happens:

--------------------------------------------------------------------------- ModuleNotFoundError Traceback (most recent call last) 1 import ree ModuleNotFoundError: No module named 'ree'

To solve this error, ensure the module name is correct. Let’s look at the revised code:

import re print(re.__version__)

You may want to import a local module file, but the module is not in the same directory. Let’s look at an example package with a script and a local module to import. Let’s look at the following steps to perform from your terminal:

mkdir example_package cd example_package mkdir folder_1 cd folder_1 vi module.py

Note that we use Vim to create the module.py file in this example. You can use your preferred file editor, such as Emacs or Atom. In module.py , we will import the re module and define a simple function that prints the re version:

import re def print_re_version(): print(re.__version__)

Close the module.py , then complete the following commands from your terminal:

Inside script.py , we will try to import the module we created.

import module if __name__ == '__main__': mod.print_re_version()

Let’s run python script.py from the terminal to see what happens:

Traceback (most recent call last): File "script.py", line 1, in ≺module≻ import module ModuleNotFoundError: No module named 'module'

To solve this error, we need to point to the correct path to module.py , which is inside folder_1 . Let’s look at the revised code:

import folder_1.module as mod if __name__ == '__main__': mod.print_re_version()

When we run python script.py , we will get the following result:

You can also get the error by overriding the official module you want to import by giving your module the same name.

Lastly, you can encounter the modulenotfounderror when you import a module that is not installed in your Python environment.

What is psutil?

psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, networks, sensors) in Python.

The simplest way to install psutil is to use the package manager for Python called pip . The following installation instructions are for the major Python version 3.

Always Use a Virtual Environment to Install Packages

It is always best to install new libraries within a virtual environment. You should not install anything into your global Python interpreter when you develop locally. You may introduce incompatibilities between packages, or you may break your system if you install an incompatible version of a library that your operating system needs. Using a virtual environment helps compartmentalize your projects and their dependencies. Each project will have its environment with everything the code needs to run. Most ImportErrors and ModuleNotFoundErrors occur due to installing a library for one interpreter and trying to use the library with another interpreter. Using a virtual environment avoids this. In Python, you can use virtual environments and conda environments. We will go through how to install psutil with both.

How to Install psutil on Windows Operating System

First, you need to download and install Python on your PC. Ensure you select the install launcher for all users and Add Python to PATH checkboxes. The latter ensures the interpreter is in the execution path. Pip is automatically on Windows for Python versions 2.7.9+ and 3.4+.

You can check your Python version with the following command:

You can install pip on Windows by downloading the installation package, opening the command line and launching the installer. You can install pip via the CMD prompt by running the following command.

You may need to run the command prompt as administrator. Check whether the installation has been successful by typing.

You can activate the environment by typing the command:

You will see “ env ” in parenthesis next to the command line prompt. You can install psutil within the environment by running the following command from the command prompt.

python3 -m pip install psutil

We use python -m pip to execute pip using the Python interpreter we specify as Python. Doing this helps avoid ImportError when we try to use a package installed with one version of Python interpreter with a different version. You can use the command which python to determine which Python interpreter you are using.

How to Install psutil on Mac Operating System using pip

Open a terminal by pressing command (⌘) + Space Bar to open the Spotlight search. Type in terminal and press enter. To get pip, first ensure you have installed Python3:

Download pip by running the following curl command:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

The curl command allows you to specify a direct download link. Using the -o option sets the name of the downloaded file.

To install psutil , first, create the virtual environment:

Then activate the environment using:

You will see “ env ” in parenthesis next to the command line prompt. You can install psutil within the environment by running the following command from the command prompt.

python3 -m pip install psutil

How to Install psutil on Linux Operating Systems

All major Linux distributions have Python installed by default. However, you will need to install pip. You can install pip from the terminal, but the installation instructions depend on the Linux distribution you are using. You will need root privileges to install pip. Open a terminal and use the commands relevant to your Linux distribution to install pip.

Installing pip for Ubuntu, Debian, and Linux Mint

sudo apt install python-pip3

Installing pip for CentOS 8 (and newer), Fedora, and Red Hat

sudo dnf install python-pip3

Installing pip for CentOS 6 and 7, and older versions of Red Hat

sudo yum install epel-release sudo yum install python-pip3

Installing pip for Arch Linux and Manjaro

Installing pip for OpenSUSE

psutil installation on Linux with Pip

To install psutil , first, create the virtual environment:

Then activate the environment using:

You will see “ env ” in parenthesis next to the command line prompt. You can install psutil within the environment by running the following command from the command prompt.

Once you have activated your virtual environment, you can install psutil using:

python3 -m pip install psutil

Installing psutil Using Anaconda

Anaconda is a distribution of Python and R for scientific computing and data science. You can install Anaconda by going to the installation instructions. Once you have installed Anaconda, you can create a virtual environment and install psutil .

To create a conda environment you can use the following command:

conda create -n project python=3.8

You can specify a different Python 3 version if you like. Ideally, choose the latest version of Python. Next, you will activate the project container. You will see “ project ” in parentheses next to the command line prompt.

Now you’re ready to install psutil using conda.

Once you have installed Anaconda and created your conda environment, you can install psutil using the following command:

conda install -c conda-forge psutil

Check psutil Version

Once you have successfully installed psutil , you can check its version. If you used pip to install psutil , you can use pip show from your terminal.

python3 -m pip show psutil

Name: psutil Version: 5.8.0 Summary: Cross-platform lib for process and system monitoring in Python. Home-page: https://github.com/giampaolo/psutil

Second, within your python program, you can import psutil and then reference the __version__ attribute:

import psutil print(psutil.__version__)

If you used conda to install psutil , you could check the version using the following command:

# Name Version Build Channel psutil 5.9.1 py38h0dd4459_0 conda-forge

Using psutil Example

Let’s look at an example of using the psutil module to retrieve CPU statistics as a named tuple.

import psutil print("CPU Statistics", psutil.cpu_stats())

CPU Statistics scpustats(ctx_switches=82582, interrupts=674761, soft_interrupts=61633675, syscalls=1680809)

  Summary

  psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network, sensors) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by classic UNIX command line tools such as ps, top, iotop, lsof, netstat, ifconfig, free and others. psutil currently supports the following platforms:

  Supported Python versions are 2.7, 3.4+ and PyPy.

  Funding

  While psutil is free software and will always be, the project would benefit immensely from some funding. Keeping up with bug reports and maintenance has become hardly sustainable for me alone in terms of time. If you’re a company that’s making significant use of psutil you can consider becoming a sponsor via GitHub Sponsors, Open Collective or PayPal and have your logo displayed in here and psutil doc.
