As a data scientist, one of the most common tools we use on a daily basis is Jupyter Notebook, an open-source web application that allows us to create and share documents that contain live code, equations, visualizations, and narrative text. Unfortunately, there are times when we encounter issues with Jupyter Notebook, and one of the most common is “Cannot open new Jupyter Notebook [Permission Denied].” In this blog post, we’ll explore what this error message means, why it occurs, and how to solve it.

What does “Cannot open new Jupyter Notebook [Permission Denied]” mean?

When you see the error message “Cannot open new Jupyter Notebook [Permission Denied],” it means that you do not have the necessary permissions to create a new Jupyter Notebook. This error typically occurs when you try to create a new notebook in a directory where you do not have write permissions.

Why does “Cannot open new Jupyter Notebook [Permission Denied]” occur?

There are several reasons why you might encounter the “Cannot open new Jupyter Notebook [Permission Denied]” error message:

1. You do not have write permissions in the directory.

The most common reason why you might see this error message is that you do not have write permissions in the directory where you are trying to create a new Jupyter Notebook. By default, Jupyter Notebook will try to create new notebooks in the directory where you launched the Jupyter Notebook server. If you do not have write permissions in that directory, you will not be able to create new notebooks.

2. The directory is owned by another user.

Another reason why you might see this error message is that the directory where you are trying to create a new Jupyter Notebook is owned by another user. In this case, you will need to ask the owner of the directory to grant you write permissions.

3. The directory is read-only.

If the directory where you are trying to create a new Jupyter Notebook is read-only, you will not be able to create new notebooks. In this case, you will need to either change the permissions on the directory or create a new directory with write permissions.

How to solve “Cannot open new Jupyter Notebook [Permission Denied]”

If you encounter the “Cannot open new Jupyter Notebook [Permission Denied]” error message, there are several steps you can take to solve the issue:

1. Check your permissions.

The first step is to check your permissions in the directory where you are trying to create a new Jupyter Notebook. You can do this by opening a terminal window and navigating to the directory in question. Once you are in the directory, type “ls -l” to list the contents of the directory and their permissions. Look for the permissions of the directory itself and make sure that you have write permissions.

2. Change the permissions on the directory.

If you do not have write permissions in the directory, you can change the permissions using the “chmod” command. For example, if you want to give yourself write permissions on a directory called “my_project,” you would type:

⚠ This code is experimental content and was generated by AI. Please refer to this code as experimental only since we cannot currently guarantee its validity

chmod u+w my_project

This will give the owner of the directory (which should be you) write permissions.

3. Create a new directory with write permissions.

If you cannot change the permissions on the directory where you are trying to create a new Jupyter Notebook, you can create a new directory with write permissions. To do this, navigate to a directory where you have write permissions and create a new directory using the “mkdir” command. For example, if you want to create a new directory called “my_notebooks” in your home directory, you would type:

⚠ This code is experimental content and was generated by AI. Please refer to this code as experimental only since we cannot currently guarantee its validity

mkdir ~/my_notebooks

4. Launch Jupyter Notebook from the new directory.

Once you have created a new directory with write permissions, you can launch Jupyter Notebook from that directory using the following command:

⚠ This code is experimental content and was generated by AI. Please refer to this code as experimental only since we cannot currently guarantee its validity

jupyter notebook --notebook-dir=/path/to/new/directory

Replace “/path/to/new/directory” with the path to the new directory you created in step 3. This will launch Jupyter Notebook from the new directory, and you should be able to create new notebooks without encountering the “Cannot open new Jupyter Notebook [Permission Denied]” error message.

Conclusion

Encountering the “Cannot open new Jupyter Notebook [Permission Denied]” error message can be frustrating, but it is usually easy to solve. By checking your permissions, changing the permissions on the directory, or creating a new directory with write permissions, you should be able to create new Jupyter Notebooks without any issues. As a data scientist, it’s important to be familiar with these types of errors and how to solve them, so that you can focus on what really matters: analyzing data and building models.
