 ### Jupyterlab container customizations
-- Starting by the configuration of jupyterlab container ([Dockerfile](./jupyterlab/Dockerfile)), we used a recent docker image (jupyter/tensorflow-notebook:python-3.10) that includes Python3.10 and the commonly used packages in machine and deep learning.
+- Starting by the configuration of jupyterlab container ([Dockerfile](./jupyterlab/Dockerfile)), we used a recent docker image (jupyter/tensorflow-notebook:python-3.11.5) that includes Python3.10 and the commonly used packages in machine and deep learning.
 - Install linux packages that might be need for running the image (via ```apt install```).
 - Install python packages that might be need for running the image including ([nb_conda_kernels](https://github.com/Anaconda-Platform/nb_conda_kernels)) which is used to manage kernels for JupyterLab/Jupyter Notebook. 
 - Prepare a configuration file for jupyter named "jupyter_config.json" with following contents:

       - DOCKER_NETWORK_NAME is the name of the Docker network used by the services; normally, this network gets an automatic name from Docker Compose, but the Hub needs to know this name to connect the single-user servers to it.
       - DOCKER_NOTEBOOK_DIR is the directory inside the single-user server containers where the user's home directory will be mounted.
       - HUB_IP is the IP address of the Hub service within the docker network. By using the container_name Compose directive, we can set an alias for the IP, and use the same for HUB_IP.
