How to use virtual environments in Jupyter Notebook?

Step 1: Install Virtual Environment
First, you need to install the virtual environment. You can do this by using pip, which is a package manager for Python. Open your terminal and type the following command:

pip install virtualenv

Step 2: Create a Virtual Environment
Next, you need to create a virtual environment. You can do this by typing the following command in your terminal:

virtualenv myenv

Replace "myenv" with the name you want to give to your virtual environment.

Step 3: Activate the Virtual Environment
After creating the virtual environment, you need to activate it. If you are using a Unix or MacOS system, type the following command:

source myenv/bin/activate

If you are using Windows, type the following command:

myenv\Scripts\activate

Step 4: Install Jupyter Notebook in the Virtual Environment
Now that your virtual environment is activated, you can install Jupyter Notebook in it. Type the following command in your terminal:

pip install jupyter

Step 5: Start Jupyter Notebook
You can now start Jupyter Notebook by typing the following command in your terminal:

jupyter notebook

This will open Jupyter Notebook in your web browser.

Step 6: Use the Virtual Environment in Jupyter Notebook
To use the virtual environment in Jupyter Notebook, you need to create a new notebook. Click on "New" and then select "Python 3" from the dropdown menu. You can now start using the virtual environment in your notebook.

Remember, whenever you want to use this virtual environment, you need to activate it first by using the "activate" command mentioned in step 3. When you are done, you can deactivate the environment by simply typing "deactivate" in your terminal.
