This warning is indicating that the `tqdm` package, which is used to display progress bars, cannot find the `IProgress` widget, which is part of the `ipywidgets` library. `IProgress` is used for displaying progress bars in Jupyter notebooks. To fix this issue, you should update `jupyter` and `ipywidgets` as suggested in the warning message. Here are the steps to resolve the issue: 1. **Update ipywidgets**: Use pip or conda to update `ipywidgets`. For pip, use the following command: ```bash pip install -U ipywidgets ``` Or for Conda, use: ```bash conda update -c conda-forge ipywidgets ``` 2. **Update Jupyter**: Similarly, update Jupyter to the latest version: ```bash pip install -U notebook jupyter ``` Or for Conda, use: ```bash conda update -c conda-forge notebook jupyter_core jupyter_client ``` 3. **Enable the widgets extension**: If it's not enabled, you will also need to ensure the Jupyter notebook extension for ipywidgets is enabled: ```bash jupyter nbextension enable --py --sys-prefix widgetsnbextension ``` 4. **Restart Jupyter Notebook**: If you had Jupyter Notebook running while you performed the updates, you'll need to restart it for the changes to take effect. 5. **Re-run your code**: After restarting Jupyter Notebook, try re-running your code to see if the warning is resolved. In case you're running a JupyterLab rather than classic Jupyter Notebook, make sure that the JupyterLab version is compatible with the `ipywidgets` version you have installed and also ensure that the JupyterLab extension for ipywidgets is installed and enabled using: ```bash jupyter labextension install @jupyter-widgets/jupyterlab-manager ``` Remember to use the correct package manager (`pip` versus `conda`) depending on your Python environment and whether you're in a virtual environment or not. If the problem persists even after updating, you may want to ensure that your environment's PATH is correctly set and that you don't have conflicting installations of Python or Jupyter. Lastly, for general troubleshooting or if you encounter different error messages, it might be helpful to check the official tqdm and ipywidgets documentation or community forums for more specific guidance.
