Why can't I find certain modules in Jupyter Notebook that are available in Python?

Step 1: Verify Python Version
First, check the Python version you're using in Jupyter Notebook and the one you're using outside of it. They should be the same. You can check the Python version by typing "python --version" in your terminal and "!python --version" in a Jupyter Notebook cell.

Step 2: Check the Python Path
Next, check the Python path Jupyter Notebook is using. You can do this by typing "import sys; sys.executable" in a Jupyter Notebook cell. This will return the path of the Python executable Jupyter is using.

Step 3: Install the Module
If the Python versions are the same and the paths are correct, you may need to install the module in the Python environment Jupyter is using. You can do this by typing "!pip install module_name" in a Jupyter Notebook cell, replacing "module_name" with the name of the module you're trying to use.

Step 4: Restart the Kernel
After installing the module, you may need to restart the Jupyter Notebook kernel to make the new module available. You can do this by clicking on "Kernel" in the Jupyter Notebook menu and then clicking on "Restart".

Step 5: Import the Module
Finally, try importing the module again by typing "import module_name" in a Jupyter Notebook cell. If the module is still not available, there may be an issue with your Python environment or the module itself.
