Introduction:
In this tutorial, we will explore the common issue of encountering the “Wrong URL opened after changing the browser” error when working with IPython Notebook. This problem often occurs when you have switched your default web browser or updated your browser settings, and it can disrupt your workflow. We will explain why this issue arises and provide steps to resolve it, along with code examples.
Prerequisites:
Why Does the Error Occur?
When you open an IPython Notebook, it typically opens in your default web browser. If you change your default browser or modify browser settings, IPython Notebook may not open correctly. This issue occurs because the notebook tries to open in the old browser, leading to a “Wrong URL opened” error.
How to Resolve the Issue:
To fix this problem, you need to update the IPython Notebook configuration to specify the browser you want to use. Follow these steps to resolve the issue:
Step 1: Locate the IPython Configuration File:
Open a terminal or command prompt.
Type the following command and press Enter:
This command generates a Jupyter configuration file if one doesn’t already exist. The file will be created at ~/.jupyter/jupyter_notebook_config.py on Unix-based systems (Linux or macOS) or %USERPROFILE%/.jupyter/jupyter_notebook_config.py on Windows.
Step 2: Edit the Configuration File:
Use a text editor to open the generated configuration file.
On Unix-based systems, you can use a command like:
On Windows, you can open the file using a text editor like Notepad.
In the configuration file, locate the line that specifies the browser and set it to your preferred browser. For example:
Replace ‘firefox’ with the name of your preferred browser. Ensure that you use the correct browser name; you may find it in the system’s environment variables.
Save and close the configuration file.
Step 3: Test the Changes:
Code Example:
Here’s a code example that demonstrates how to set the browser configuration in the Jupyter Notebook configuration file:
Conclusion:
By following the steps outlined in this tutorial, you can resolve the “Wrong URL opened after changing the browser” issue when using IPython Notebook. Updating the Jupyter Notebook configuration file to specify your preferred browser is a simple and effective way to ensure that your notebook opens correctly in the desired browser.
