The error you're seeing, "Import 'matplotlib.pyplot' could not be resolved from source", typically means that your Python environment or IDE (like VS Code) can’t find the matplotlib library. This is a common issue for beginners, and it’s usually related to your Python environment setup. Here’s how we can resolve it:
Check if matplotlib is installed:
First, ensure that matplotlib is installed in the Python environment you're using. Since you mentioned .venv (a virtual environment) and a 64-bit Python interpreter, it’s possible the library isn’t installed in the environment your IDE is pointing to.
Open your IDE’s terminal (in VS Code, this is the "integrated terminal," not necessarily Apple Terminal). To do this:
If you’re using a virtual environment (like .venv), activate it:
On macOS/Linux: source .venv/bin/activate
On Windows: .venv\Scripts\activate
You’ll know it’s active if your terminal prompt changes (e.g., (.venv) appears).
Once activated, check if matplotlib is installed by running (in windows): pip list | grep matplotlib
Make sure your import statement is correct. It should look like this: import matplotlib.pyplot as plt
