Not able to open .ipynb file

It looks like you are having trouble opening an .ipynb file. .ipynb files are Jupyter Notebook files that contain a combination of code and text. In order to open an .ipynb file, you will need to have a program installed that is capable of handling this type of file.

One option is to use the Jupyter Notebook app. This is a free, open-source application that allows you to create and work with .ipynb files. To install the Jupyter Notebook app, you will need to have Python installed on your computer. You can then use pip, the Python package manager, to install the Jupyter Notebook package.

Here is the command to install Jupyter Notebook:

pip install jupyter

Once you have installed Jupyter, you can launch the Jupyter Notebook app by running the following command:

jupyter notebook

This will open the Jupyter Notebook app in your web browser. You can then use the app to open and view the .ipynb file.

Alternatively, you can use a text editor such as Sublime Text or Atom to open and view the contents of an .ipynb file. These text editors can display the code and text contained in the file, but they will not be able to execute the code.
