Tensorboard not found as magic function in jupyter
extension loading is required before. You can try -> %load_ext tensorboard 
.It worked for me. I am using TensorFlow 1.>
I want to run tensorboard in jupyter using the latest tensorflow 2.0.0a0. 
With the tensorboard version 1.13.1, and python 3.6. 
using 
...
%tensorboard --logdir {logs_base_dir}
I get the error :
UsageError: Line magic function %tensorboard not found
Do you have an idea what the problem could be? It seems that all versions are up to date and the command seems correct too. 
Thanks
