It seems like there might be an issue with the Python environment that Power BI is using. Let's try a few troubleshooting steps to resolve the problem:

  1. Ensure Power BI is Using the Correct Python Environment: Make sure that Power BI is using the correct Python environment where Matplotlib is installed. You can specify the Python script settings in Power BI. Follow these steps:

    • In Power BI Desktop, go to "File" > "Options and settings" > "Options."
    • In the "Options" dialog, go to "Python scripting."
    • Specify the path to the correct Python executable in the "Detected Python home directories" or "Python home directory" field.

  2. Check Python Path: Ensure that the Python path where Matplotlib is installed is included in the system's PATH environment variable. This can be set either globally or within the Power BI Python options.

  3. Install Matplotlib Using Power BI's Python Environment: Open Power BI and run the following Python script in the Python script editor to install Matplotlib:

import subprocess
subprocess.check_call(["python", "-m", "pip", "install", "matplotlib"])

 

  1. This script uses the Python interpreter that Power BI is configured to use. After running this script, try your Matplotlib script again.

  2. Restart Power BI: After making changes to Python configurations or installing packages, it's a good idea to restart Power BI to ensure the changes take effect.

  3. Use Virtual Environment (Optional): Consider using a virtual environment for your Python script within Power BI. This can help isolate dependencies and avoid conflicts.

  4. Check Python Version Compatibility: Ensure that the version of Python installed matches the version supported by Matplotlib. You can check Matplotlib's documentation for compatibility information.

  5. Review Security Policies: Check if there are any security policies or antivirus programs that might be blocking Power BI from accessing Python libraries. Ensure that the required permissions are granted.

  6. Reinstall Power BI: As a last resort, if the issue persists, consider reinstalling Power BI to ensure a clean installation.
