ModuleNotFoundError: No module named 'd2l'

This error message indicates that the Python interpreter cannot find a module named 'd2l'. This may occur due to one of the following reasons:
1. The module is not installed: You need to install the 'd2l' module using pip, which is the package manager for Python. You can do this by running the following command in a terminal or command prompt:
```
pip install d2l
```
2. The module is installed but not visible: If you have installed 'd2l' but still get the error message, it may be because the Python interpreter is not looking in the right place for the module. You can try adding the directory where 'd2l' is installed to your Python path. For example, if the module is installed in '/usr/local/lib/python3.8/site-packages/d2l', you can add this directory to your path by running:
```
export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.8/site-packages
```
For Windows users, the command would be:
```
set PYTHONPATH=%PYTHONPATH%;C:\Python\lib\site-packages
```
You can replace the directory path with the actual path where 'd2l' is installed on your system.
3. The module name is misspelled: Check the spelling of the module name and make sure it is correct. Python is case-sensitive, so 'd2l' is not the same as 'D2L' or 'D2l'.
Once you have resolved the issue, you should be able to import the 'd2l' module without any errors.
