Install NumPy in VS Code

Without delay, here are all the steps you’ll need to take to install NumPy:

  1. Fire up VS Code. If, by chance, you don’t have it already download a copy from the official website.
  2. Click on the Extension tab. You can find it on the left side of the window, denoted by a four-squared icon.
  3. Type “Python” into the extension search bar.
  4. Select “Python from Microsoft” from the results.
  5. Click on the blue “Install” button.
  6. Go back to the main menu.
  7. Select “Terminal.”
  8. Choose “New Terminal.”
  9. To get started with NumPy, enter this command into the Terminal you just opened:

    pip install numpy

    .

This tells the Python package installer to download NumPy and install it on your computer. The process from then on is automatic.

The Python extension you downloaded also gives an abundance of support for your other Python projects, such as IntelliSense, linting, or debugging.

If you run into any roadblocks that mention “no module named numpy” as an error message, double-check if you selected the right Python interpreter. You can adjust this by navigating to “Python” in the lower region of the screen and selecting the interpreter which has pip and NumPy.

What is Pandas?

Before we dive into the installation process, let’s first define what Pandas is and why it’s so useful. Pandas is a Python library that provides data manipulation and analysis tools. It’s built on top of the NumPy library, which provides support for large, multi-dimensional arrays and matrices. Pandas makes it easy to work with data in a variety of formats, including CSV, Excel, SQL databases, and more.

Some of the key features of Pandas include:

  • Dataframe and series objects for working with tabular data
  • Support for data cleaning, filtering, and transformation
  • Built-in support for handling missing or null values
  • Integration with other Python libraries, such as Matplotlib and Scikit-learn

Now that you know what Pandas is and what it can do, let’s move on to the installation process.

Python NumPy is a general-purpose array processing package that provides tools for handling n-dimensional arrays. It provides various computing tools such as comprehensive mathematical functions, and linear algebra routines. NumPy provides both the flexibility of Python and the speed of well-optimized compiled C code. Its easy-to-use syntax makes it highly accessible and productive for programmers from any background. In this article, we will see how to install NumPy as well as how to import Numpy in Python.

Pre-requisites:

Installing Numpy on Windows

Below are the ways by which we can install NumPy on Windows and later on import Numpy in Python:

Install Numpy Using Conda

If you want the installation to be done through conda, you can use the below command:

conda install -c anaconda numpy

You will get a similar message once the installation is complete

Make sure you follow the best practices for installation using conda as:

  • Use an environment for installation rather than in the base environment using the below command:

conda create -n my-envconda activate my-env

Note: If your preferred method of installation is conda-forge, use the below command:

conda config –env –add channels conda-forge

Installing Numpy For PIP Users

Users who prefer to use pip can use the below command to install NumPy:

pip install numpy

You will get a similar message once the installation is complete:

Now that we have installed Numpy successfully in our system, let’s take a look at few simple examples.

Example of Numpy

In this example, a 2D NumPy array named

arr

is created, and its characteristics are demonstrated: the array type, number of dimensions (2), shape (2 rows, 3 columns), size (6 elements), and the data type of its elements (int64).

How to Install Pandas in Visual Studio Code

Installing Pandas in Visual Studio Code is a straightforward process that can be completed in just a few steps. Here’s what you need to do:

Step 1: Install Python

Before you can install Pandas, you need to have Python installed on your computer. If you haven’t already done so, you can download the latest version of Python from the official Python website (https://www.python.org/downloads/). Be sure to download the version that matches your operating system (Windows, macOS, or Linux).

Step 2: Open Visual Studio Code

Once you have Python installed, you can open Visual Studio Code. If you don’t already have it installed, you can download it from the official Visual Studio Code website (https://code.visualstudio.com/download).

Step 3: Open the Terminal

In Visual Studio Code, click on the Terminal tab at the top of the screen. This will open a new terminal window at the bottom of the screen.

Step 4: Install Pandas

In the terminal window, type the following command to install Pandas:


pip install pandas

This will download and install the latest version of Pandas from the Python Package Index (PyPI). Depending on your internet connection speed, this process may take a few minutes. You can also choose the specific version of Pandas that you want to install by typing the following command:


pip install pandas==2.1.1 # this command will install Pandas version 2.1.1 to your computer.

Step 5: Verify the Installation

Once the installation is complete, you can verify that Pandas has been installed correctly by typing the following command in the terminal window:


python -c "import pandas; print(pandas.__version__)"

This will print the version number of Pandas that you just installed, either the latest version or the specific one that you defined. If you see a version number, then Pandas has been installed correctly.

Run Python code

Click the Run Python File in Terminal play button in the top-right side of the editor.

The button opens a terminal panel in which your Python interpreter is automatically activated, then runs

python3 hello.py

(macOS/Linux) or

python hello.py

(Windows):

There are three other ways you can run Python code within VS Code:

  1. Right-click anywhere in the editor window and select Run > Python File in Terminal (which saves the file automatically):

  2. Select one or more lines, then press Shift+Enter or right-click and select Run Selection/Line in Python Terminal. This command is convenient for testing just a part of a file.

  3. From the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)), select the Python: Start REPL command to open a REPL terminal for the currently selected Python interpreter. In the REPL, you can then enter and run lines of code one at a time.

Congrats, you just ran your first Python code in Visual Studio Code!

Configure and run the debugger

Let’s now try debugging our Python program. Debugging support is provided by the Python Debugger extension, which is automatically installed with the Python extension. To ensure it has been installed correctly, open the Extensions view (⇧⌘X (Windows, Linux Ctrl+Shift+X)) and search for

@installed python debugger

. You should see the Python Debugger extension listed in the results.

Next, set a breakpoint on line 2 of

hello.py

by placing the cursor on the

Next, to initialize the debugger, press F5. Since this is your first time debugging this file, a configuration menu will open from the Command Palette allowing you to select the type of debug configuration you would like for the opened file.

Note: VS Code uses JSON files for all of its various configurations;


launch.json

is the standard name for a file containing debugging configurations.

Select Python File, which is the configuration that runs the current file shown in the editor using the currently selected Python interpreter.

The debugger will start, and then stop at the first line of the file breakpoint. The current line is indicated with a yellow arrow in the left margin. If you examine the Local variables window at this point, you can see that the

msg

variable appears in the Local pane.

A debug toolbar appears along the top with the following commands from left to right: continue (F5), step over (F10), step into (F11), step out (⇧F11 (Windows, Linux Shift+F11)), restart (⇧⌘F5 (Windows, Linux Ctrl+Shift+F5)), and stop (⇧F5 (Windows, Linux Shift+F5)).

The Status Bar also changes color (orange in many themes) to indicate that you’re in debug mode. The Python Debug Console also appears automatically in the lower right panel to show the commands being run, along with the program output.

To continue running the program, select the continue command on the debug toolbar (F5). The debugger runs the program to the end.

Tip Debugging information can also be seen by hovering over code, such as variables. In the case of


msg

, hovering over the variable will display the string

Roll a dice!

in a box above the variable.

You can also work with variables in the Debug Console (If you don’t see it, select Debug Console in the lower right area of VS Code, or select it from the … menu.) Then try entering the following lines, one by one, at the > prompt at the bottom of the console:


msg msg.capitalize() msg.split()

Select the blue Continue button on the toolbar again (or press F5) to run the program to completion. “Roll a dice!” appears in the Python Debug Console if you switch back to it, and VS Code exits debugging mode once the program is complete.

If you restart the debugger, the debugger again stops on the first breakpoint.

To stop running a program before it’s complete, use the red square stop button on the debug toolbar (⇧F5 (Windows, Linux Shift+F5)), or use the Run > Stop debugging menu command.

For full details, see Debugging configurations, which includes notes on how to use a specific Python interpreter for debugging.

Tip: Use Logpoints instead of print statements: Developers often litter source code with

You may not have numpy installed on the version of python you are running.

Try this:

import sys

print(sys.version)

Is the printed version Anaconda? If you installed Anaconda python, it should come with numpy already installed. If it turns out to be another version of python you are accessing inside Visual Studio Code that doesn’t have numpy installed, then that’s what you need to fix.

The version of python that is called depends on which version of python comes up in your PATH variable first. Type into a terminal:

echo $PATH

.
The output should look like this with Anaconda bin first:

/Users/jlzhang/anaconda/bin:/usr/local/bin:/usr/bin:/bin

If you do not have Anaconda bin first, you can add this to your ~/.bashrc file:
echo

# Use Anaconda python

export PATH=”/Users/jlzhang/anaconda/bin:$PATH”

Restart a terminal and Visual Studio Code and see if you are now running Anaconda python.

Common Ways to Use NumPy

Here are some examples of how to use NumPy in your projects:

  1. Creating arrays: You can create NumPy arrays using various functions, such as

    np.array()

    ,

    np.zeros()

    , and

    np.ones()

    .


import numpy as np # Creating a 1D array arr1 = np.array([1, 2, 3, 4, 5]) print("1D array:", arr1) # Creating a 2D array filled with zeros arr2 = np.zeros((3, 3)) print("2D array filled with zeros:", arr2) # Creating a 3D array filled with ones arr3 = np.ones((2, 2, 2)) print("3D array filled with ones:", arr3)

  1. Performing mathematical operations: NumPy makes it easy to perform element-wise mathematical operations on arrays.


import numpy as np a = np.array([1, 2, 3]) b = np.array([4, 5, 6]) # Element-wise addition sum = a + b print("Sum:", sum) # Element-wise multiplication product = a * b print("Product:", product) # Squaring elements in the array squared = a**2 print("Squared:", squared)

Create a virtual environment

A best practice among Python developers is to use a project-specific

virtual environment

. Once you activate that environment, any packages you then install are isolated from other environments, including the global interpreter environment, reducing many complications that can arise from conflicting package versions. You can create non-global environments in VS Code using Venv or Anaconda with Python: Create Environment.

Open the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)), start typing the Python: Create Environment command to search, and then select the command.

The command presents a list of environment types, Venv or Conda. For this example, select Venv.

The command then presents a list of interpreters that can be used for your project. Select the interpreter you installed at the beginning of the tutorial.

After selecting the interpreter, a notification will show the progress of the environment creation and the environment folder (

/.venv

) will appear in your workspace.

Ensure your new environment is selected by using the Python: Select Interpreter command from the Command Palette.

Note: For additional information about virtual environments, or if you run into an error in the environment creation process, see Environments.

Install a Python interpreter

Along with the Python extension, you need to install a Python interpreter. Which interpreter you use is dependent on your specific needs, but some guidance is provided below.

Windows

Install Python from python.org. Use the Download Python button that appears first on the page to download the latest version.

Note: If you don’t have admin access, an additional option for installing Python on Windows is to use the Microsoft Store. The Microsoft Store provides installs of supported Python versions.

For additional information about using Python on Windows, see Using Python on Windows at Python.org

macOS

The system install of Python on macOS is not supported. Instead, a package management system like Homebrew is recommended. To install Python using Homebrew on macOS use

brew install python3

at the Terminal prompt.

Note: On macOS, make sure the location of your VS Code installation is included in your PATH environment variable. See these setup instructions for more information.

Linux

The built-in Python 3 installation on Linux works well, but to install other Python packages you must install

pip

with get-pip.py.

Other options

  • Data Science: If your primary purpose for using Python is Data Science, then you might consider a download from Anaconda. Anaconda provides not just a Python interpreter, but many useful libraries and tools for data science.

  • Windows Subsystem for Linux: If you are working on Windows and want a Linux environment for working with Python, the Windows Subsystem for Linux (WSL) is an option for you. If you choose this option, you’ll also want to install the WSL extension. For more information about using WSL with VS Code, see VS Code Remote Development or try the Working in WSL tutorial, which will walk you through setting up WSL, installing Python, and creating a Hello World application running in WSL.

Note: To verify that you’ve installed Python successfully on your machine, run one of the following commands (depending on your operating system):

Linux/macOS: open a Terminal Window and type the following command:


python3 --version

Windows: open a command prompt and run the following command:


py -3 --version

If the installation was successful, the output window should show the version of Python that you installed. Alternatively, you can use the


py -0

command in the VS Code integrated terminal to view the versions of python installed on your machine. The default interpreter is identified by an asterisk (*).

How to Install Pandas into Visual Studio Code

As a data scientist or software engineer, you know the importance of having the right tools in your toolbox. One of the most popular tools for data analysis in Python is the Pandas library. In this article, we’ll show you how to install Pandas into Visual Studio Code, a popular integrated development environment (IDE) for Python.

How To Create & Activate A Virtual Environment In Visual Studio Code (Python 3.12)
How To Create & Activate A Virtual Environment In Visual Studio Code (Python 3.12)

Install and use packages

Let’s build upon the previous example by using packages.

In Python, packages are how you obtain any number of useful code libraries, typically from PyPI, that provide additional functionality to your program. For this example, you use the

numpy

package to generate a random number.

Return to the Explorer view (the top-most icon on the left side, which shows files), open

hello.py

, and paste in the following source code:


import numpy as np msg = "Roll a dice" print(msg) print(np.random.randint(1,9))

Tip: If you enter the above code by hand, you may find that auto-completions change the names after the


as

keywords when you press Enter at the end of a line. To avoid this, type a space, then Enter.

Next, run the file in the debugger using the “Python: Current file” configuration as described in the last section.

You should see the message, “ModuleNotFoundError: No module named ‘numpy'”. This message indicates that the required package isn’t available in your interpreter. If you’re using an Anaconda distribution or have previously installed the

numpy

package you may not see this message.

To install the

numpy

package, stop the debugger and use the Command Palette to run Terminal: Create New Terminal (⌃⇧` (Windows, Linux Ctrl+Shift+`)). This command opens a command prompt for your selected interpreter.

To install the required packages in your virtual environment, enter the following commands as appropriate for your operating system:

  1. Install the packages


    # Don't use with Anaconda distributions because they include matplotlib already. # macOS python3 -m pip install numpy # Windows (may require elevation) py -m pip install numpy # Linux (Debian) apt-get install python3-tk python3 -m pip install numpy

  2. Now, rerun the program, with or without the debugger, to view the output!

Congrats on completing the Python tutorial! During the course of this tutorial, you learned how to create a Python project, create a virtual environment, run and debug your Python code, and install Python packages.

Make the Most of NumPy in VS Code

With NumPy up and running, you can benefit from Visual Studio Code’s features to make your programming more effective and enjoyable.

Debugging

Programming is intricate and delicate and you’re bound to debug code that won’t do what it’s supposed to. VS Code has a comprehensive debugging environment specifically for Python applications and those that use NumPy for scientific computing. Here are some tips:

  • If you do identify a possible bug, to get to the root of the issue, you need to pull out the Python file you are working on and open it up. After that, click on “Run” from the top menu and choose “Start Debugging.” This will kick off the debugging.
  • Debugging your code can be much easier if you set breakpoints. These markers let the debugger pause your program, so you can inspect the state of your program at that exact point of execution. Try setting these breakpoints by clicking on the margin next to the line of code you’d like to pause or hovering your cursor over the line and pressing F9.
  • When the program is on pause, the debugging controls at the top of the screen will let you move through the code. If you press F10, you can skip over functions; with F11, you dive deeper into them, and pressing both Shift and F11 will step out of a function.
  • You can also look closely at the variables with the “Variables” pane. It will show up in the “Run and Debug” sidebar when your program is on pause, displaying all of the values in the local scope. If you need more detail, hover over any variable in the code to get an exact value.

Using Jupyter Notebooks

A savvy data analyst can benefit from the interactive environment of Jupyter Notebooks, accessible directly from VS Code. This way, you can construct, execute, and debug code within a seamless interface.

If you want to create a new Jupyter Notebook in Visual Studio Code:

  1. Open the Command Palette (Ctrl+Shift+P).
  2. Find the command “

    Create: New Jupyter Notebook

    .”
  3. Alternatively, open your workspace and create a new file with the “.ipynb” extension.

Once you create a notebook, you can type Python code into its cells and execute those commands by clicking the “Run Cell” button that appears when your cursor hovers over it. The results of your cell will then show up beneath it so that you can use them in other calculations or operations.

You can choose the Python interpreter for each Notebook you make by picking from the kernel picker in the top right. This option comes in handy, particularly if you have more than one Python environment on your computer and would like to use all of them, depending on the work.

Using IntelliSense

VS Code’s IntelliSense is your best friend and companion to NumPy coding. This powerful set of features grants intelligent code completion as you type. You don’t have to overthink function names, variables, etc. IntelliSense can figure it out from the code’s context.

For example, if you need to write a function, start typing the name, and IntelliSense will provide you with all of the available functions from NumPy and other modules. Select one that fits, and the tool will add it to the code. You’ll also get a correct list of arguments for each function, which also brings great speed to coding.

Upgrading Your NumPy Setup

To ensure that you have the latest features and bug fixes, it’s essential to keep your NumPy installation up-to-date. To upgrade NumPy, follow these steps:

  1. Open your terminal or command prompt.
  2. Run the following command to upgrade NumPy to the latest version:


pip install --upgrade numpy

This command will update NumPy to the latest available version.

Create a Python source code file

From the File Explorer toolbar, select the New File button on the

hello

folder:

Name the file

hello.py

, and VS Code will automatically open it in the editor:

By using the

.py

file extension, you tell VS Code to interpret this file as a Python program, so that it evaluates the contents with the Python extension and the selected interpreter.

Note: The File Explorer toolbar also allows you to create folders within your workspace to better organize your code. You can use the New folder button to quickly create a folder.

Now that you have a code file in your Workspace, enter the following source code in

hello.py

:


msg = "Roll a dice" print(msg)

When you start typing

IntelliSense and auto-completions work for standard Python modules as well as other packages you’ve installed into the environment of the selected Python interpreter. It also provides completions for methods available on object types. For example, because the

msg

variable contains a string, IntelliSense provides string methods when you type

msg.

:

Finally, save the file (⌘S (Windows, Linux Ctrl+S)). At this point, you’re ready to run your first Python file in VS Code.

NumPy with VS Code Extensions

VS Code’s extensibility is one of its most powerful features. With the correct extensions, you can supercharge both Python and NumPy. Here are a few extensions that can be particularly useful along with NumPy.

  • The Python extension by Microsoft brings intuitive coding to VS Code. It lets you write code faster, with helpful features like IntelliSense, real-time linting and formatting, debugging tools, and more.
  • The Python Docstring Generator is a lifesaver for developers who have to work on complex NumPy code. This extension will generate detailed docstrings to document the code in seconds, which saves genuinely countless hours of manual writing and formatting.
  • Python Test Explorer can run your Python tests right from the sidebar and get instant feedback on the results. There is no need to switch back and forth between applications, making it another worthwhile timesaver.
  • MagicPython is also terrific for Python developers who need to analyze and debug complicated code. Thanks to improved syntax highlighting and indentation, you’ll be able to read NumPy expressions on the fly with MagicPython.
  • Kite’s Autocomplete for Python is yet another more thoughtful way to code. It uses machine learning so that Kite can give context-aware completions for Python scripts. Instead of spending time looking up functions and methods from the library (or the Internet), you’ll find intelligent suggestions with Kite as you type. It even supports complex operations.
