How to Install NumPy and Prerequisites for NumPy in Visual Studio Code (VS Code)** **Description:** Want to use **NumPy** in **Visual Studio Code (VS Code)** but don’t know where to start? 🤔 This guide will walk you through **installing NumPy**, its **prerequisites**, and how to set up **VS Code for Python development**. By the end, you'll be ready to use **NumPy for numerical computing** in Python. 🚀 Let’s get started! 💡 — ### **🔹 What You’ll Learn in This Video:** ✅ What **NumPy** is and why it's essential ✅ The **prerequisites** for installing NumPy in **VS Code** ✅ How to **install NumPy using pip** ✅ How to **configure VS Code for Python development** ✅ How to **verify the NumPy installation** — ## **🔹 What is NumPy?**
**NumPy (Numerical Python)** is a powerful **Python library for numerical computing**. It provides **support for large, multi-dimensional arrays and matrices**, along with a vast collection of **mathematical functions**. NumPy is widely used in **data science, machine learning, and scientific computing**. — ## **1️⃣ Prerequisites for Installing NumPy in VS Code**
Before installing NumPy, make sure you have the following: ### ✅ **1. Install Python** – Download and install **Python (3.8 or later)** from the official site: 🔗 [https://www.python.org/downloads/](https://www.python.org/downloads/) – During installation, **check the box** for **"Add Python to PATH"**. **To verify Python installation**, open **Command Prompt (Windows) or Terminal (Mac/Linux)** and run: “`bash
python –version
“`
or “`bash
python3 –version
“`
✔ If Python is installed, you'll see the version displayed. — ### ✅ **2. Install Visual Studio Code (VS Code)** – Download and install **VS Code** from: 🔗 [https://code.visualstudio.com/](https://code.visualstudio.com/) — ### ✅ **3. Install Python Extension in VS Code** After installing VS Code, you need to install the **Python extension**: 1. Open **VS Code**. 2. Go to **Extensions** (Ctrl + Shift + X). 3. Search for **"Python"** and install the **official extension** by Microsoft. — ## **2️⃣ How to Install NumPy in VS Code**
Once Python and VS Code are set up, follow these steps to install **NumPy**: ### ✅ **1. Open VS Code Terminal** – Open **VS Code** – Press **Ctrl + ` (backtick)** to open the terminal — ### ✅ **2. Create a Virtual Environment (Recommended)**
To avoid conflicts with system libraries, it’s best to install NumPy inside a **virtual environment**. **Step 1: Create a virtual environment** “`bash
python -m venv myenv
“`
or “`bash
python3 -m venv myenv
“` **Step 2: Activate the virtual environment** – **Windows**: “`bash myenv\Scripts\activate “`
– **Mac/Linux**: “`bash source myenv/bin/activate “` — ### ✅ **3. Install NumPy Using pip**
Once the virtual environment is activated, install NumPy with: “`bash
pip install numpy
“`
or, if using Python 3: “`bash
pip3 install numpy
“` This will download and install **NumPy and its dependencies**. — ### ✅ **4. Verify the NumPy Installation**
To check if **NumPy** is installed correctly, open the Python interpreter: “`bash
python
“`
Then, type: “`python
import numpy as np
print(np.__version__)
“`
If NumPy is installed, you’ll see its version printed. 🎉 — ## **3️⃣ Troubleshooting Installation Issues**
If you encounter issues, try these solutions: **🚨 pip Command Not Found?** ✔ Ensure **Python and pip are added to PATH**. Try running: “`bash
python -m ensurepip –default-pip
“`
Then, reinstall NumPy. **🚨 NumPy Not Found in VS Code?** ✔ Make sure you are using the correct **Python interpreter** in VS Code: – Press **Ctrl + Shift + P** → Search **"Python: Select Interpreter"** – Choose the interpreter from your **virtual environment** **🚨 "ModuleNotFoundError: No module named 'numpy'"?** ✔ Activate the virtual environment before running your script: “`bash
source myenv/bin/activate # Mac/Linux
myenv\Scripts\activate # Windows
“`
Then reinstall NumPy using `pip install numpy`. — ## **📌 Conclusion** Congratulations! 🎉 You have successfully installed **NumPy** in **VS Code** and set up your Python environment.
