I’ve found a solution to make it work. I was missing from pip -> tensorboard

Here you can find the requirements:

tensorflow==2.1.0
jupyter-tensorboard==0.2.0
tensorflow-estimator==2.1.0
tensorboard==2.1.0

And for jupyter:

jupyter-client         6.1.3      
jupyter-core           4.6.3      
jupyter-kernel-gateway 2.4.0      
jupyter-telemetry      0.1.0      
jupyter-tensorboard    0.2.0      
jupyterhub             1.1.0      
jupyterlab             2.1.4         
jupyterlab-server      1.1.5    

After adding the missing req it worked like a charm. 😃
