NumPy won’t work until you install it. Sounds obvious, but plenty of developers hit “No module named numpy” errors because PyCharm doesn’t include it by default.
Learning how to install NumPy in PyCharm takes about 3 minutes and saves hours of frustration with scientific computing projects.
This guide walks through the complete installation process using JetBrains’ built-in package manager. You’ll also get a terminal alternative for pip install commands.
By the end, you’ll have NumPy running in your Python project, verified and ready for data analysis, array processing, or numerical operations.
Works on Windows, macOS, and Linux with PyCharm Community or Professional Edition.
How to Install NumPy in PyCharm
Installing NumPy in PyCharm is the process of adding the NumPy library to a Python project through the built-in package manager or terminal.
Users need this when working with numerical operations, data analysis, or scientific computing.
If you’re new to what PyCharm is, it’s JetBrains’ Python IDE with integrated package management.
This guide on how to install numpy in PyCharm covers 4 steps requiring about 3 minutes and PyCharm 2023.1 or later with Python 3.8+.
Prerequisites
Before starting the numpy installation, check these requirements:
- PyCharm Community or Professional Edition (2023.1 or later)
- Python interpreter (3.8, 3.9, 3.10, 3.11, or 3.12)
- Active internet connection for PyPI access
- Administrator permissions for global installations (optional)
- Existing PyCharm project or willingness to create one
Time estimate: 2-3 minutes.

You should also know how to add a Python interpreter in PyCharm before proceeding.
Step 1: How Do You Open the Python Packages Tool Window in PyCharm?
Access the Python Packages panel through View > Tool Windows > Python Packages in the main menu bar. The panel opens at the bottom of the IDE and displays all installed packages for your current project interpreter along with the PyPI repository search.
Action
- Menu path: View > Tool Windows > Python Packages
- Alternative: Click “Python Packages” tab at bottom of IDE (if visible)
- Result: Package management panel opens with search field and installed packages list
Purpose
The Python Packages tool window provides direct access to PyPI without leaving the IDE.
Faster than switching to terminal. Shows version info and package descriptions inline.
This approach works well if you’re already familiar with installing packages in PyCharm through the GUI.
Step 2: How Do You Search for NumPy in the Package Repository?
Type “numpy” in the search field at the top of the Python Packages panel. PyCharm queries the Python Package Index and displays matching results within 1-2 seconds, showing the official numpy package with its current version number and brief description.
Action
- Search field: Top of Python Packages panel
- Search term: numpy
- Result: numpy package appears showing version 1.26.x (or latest stable)
Purpose
Direct PyPI search confirms you’re getting the official numpy module from the Python Software Foundation.
Avoids typosquatting packages. Shows dependency info before installation.
The same search method works when you need to install pandas in PyCharm or other scientific Python libraries later.
Step 3: How Do You Install NumPy from the Search Results?
Click the “Install” button next to the numpy package listing in the search results. PyCharm downloads the library from PyPI and installs it into your project’s Python interpreter automatically.
Action
- Install button: Right side of numpy package listing
- Version selection: Click dropdown for specific version or accept latest stable (1.26.x)
- Result: Progress bar shows download and installation; green checkmark when complete
Purpose
The GUI handles pip install numpy commands behind the scenes, plus resolves dependencies automatically.
No terminal needed. Works identically on Windows, macOS, and Linux.
Step 4: How Do You Verify NumPy Installation in Your Project?
Create a test file and run a simple import to confirm numpy installed correctly. The console should display the version number without any module import errors.
Action
- Create file: Right-click project folder > New > Python File > name it “testnumpy.py”
- Test code:
import numpy as npthenprint(np.version) - Run: Right-click file > Run ‘testnumpy’ or use Shift+F10
Purpose
Confirms the numpy array library loads without errors. Version output proves installation succeeded.

Alternative Method: Terminal Installation
Some developers prefer the terminal command approach over the GUI package manager.
PyCharm GUI Method (Current Guide)
- Time: 2 minutes
- Complexity: Beginner
- Best for: Visual learners, new PyCharm users
Terminal Method
- Time: 1 minute
- Complexity: Intermediate
- Best for: Command line users, specific version pinning
To use terminal: View > Tool Windows > Terminal, then type pip install numpy.
Choose GUI when you want visual feedback. Choose Terminal when you need faster execution or requirements.txt generation.
Understanding how to install pip in PyCharm helps if your terminal shows pip not found errors.
Verification
After installation, verify numpy works in your development environment:
- Check Python Packages panel shows numpy in “Installed” tab
- Run
import numpy as np; print(np.version)in Python Console - Create a test array:
np.array([1, 2, 3])should return without errors
If numpy appears installed but import fails, your project interpreter might be misconfigured.

Troubleshooting
Issue: “No module named numpy” Error After Installation
Solution: Wrong interpreter selected. Go to File > Settings > Project > Python Interpreter and verify numpy appears in the package list for your active interpreter.
If missing, you installed numpy to a different Python environment.
Issue: Installation Fails with Permission Error
Solution: Use a virtual environment instead of system Python. Create one via File > Settings > Project > Python Interpreter > Add Interpreter > Add Local Interpreter > Virtualenv.
Need detailed steps? See how to create a virtual environment in PyCharm.
Issue: Slow Installation or Timeout
Solution: Check internet connection. Try terminal method with pip install numpy --timeout 100 for extended timeout.
Corporate networks may block PyPI; ask IT about proxy settings.
Issue: Version Compatibility Problems
Solution: Numpy 2.0+ requires Python 3.9+. For older Python versions, specify: pip install numpy==1.24.3.
Check version compatibility between numpy and your Python interpreter before installation.

FAQ on How To Install Numpy In Pycharm
Why is NumPy not installing in PyCharm?
Common causes include wrong Python interpreter selection, network issues blocking PyPI access, or insufficient permissions for system Python.
Check File > Settings > Project > Python Interpreter to verify numpy targets your active environment. Use a virtual environment if permission errors persist.
How do I install NumPy in PyCharm using pip?
Open Terminal via View > Tool Windows > Terminal. Type pip install numpy and press Enter.
PyCharm’s integrated terminal uses your project’s pip command automatically. Installation completes in 10-30 seconds depending on connection speed.
Where is the package manager in PyCharm?
Access it through View > Tool Windows > Python Packages. The panel appears at the bottom of the IDE.
Search, install, and update packages directly from this package manager interface without terminal commands.
Can I install NumPy in PyCharm Community Edition?
Yes. Both PyCharm Community and Professional editions include the Python Packages tool and terminal for library dependency management.
NumPy installation works identically in both versions. No paid features required.
How do I check if NumPy is installed in PyCharm?
Open Python Console (View > Tool Windows > Python Console) and type import numpy as np followed by print(np.version).
Version output confirms successful installation. Import errors mean numpy isn’t in your current interpreter.
Why does PyCharm say “No module named numpy” after installation?
You installed numpy to a different Python interpreter than your project uses. Multiple Python versions cause this constantly.
Verify the correct interpreter in Settings > Project > Python Interpreter. Reinstall numpy to the active environment.
How do I install a specific NumPy version in PyCharm?
In Python Packages panel, click the version dropdown next to numpy before installing. Or use terminal: pip install numpy==1.24.3.
Older projects may need specific versions for version compatibility with other dependencies.
Should I use conda or pip to install NumPy in PyCharm?
Use pip for standard virtual environments. Use conda if you created an Anaconda environment in PyCharm.
Both work fine. Pip connects to PyPI; conda uses Anaconda repositories. Don’t mix them in the same environment.
How do I install NumPy in a PyCharm virtual environment?
Create or select a virtual environment as your project interpreter first. Then install numpy normally through Python Packages or terminal.
Virtualenv isolates dependencies per project. Recommended approach for all Python development.
Does PyCharm automatically install NumPy?
No. PyCharm doesn’t auto-install third-party packages. You must add numpy manually through the package manager or pip install command.
However, PyCharm detects missing imports and offers quick-fix installation suggestions in the editor.
Conclusion
You now know how to install NumPy in PyCharm using both the GUI package manager and terminal methods.
The process works across Windows, macOS, and Linux without any differences.
Keep your Python interpreter configuration correct and most installation errors disappear. Virtual environments prevent dependency conflicts between projects.
NumPy opens the door to the entire scientific Python ecosystem. SciPy, pandas, and Matplotlib all build on it.
