`tensorboard` not available in **tutorials/nlp/Entity_Linking_Medical.ipynb**
**Describe the bug**

I'm trying to run this notebook: https://github.com/NVIDIA/NeMo/blob/v1.0.2/tutorials/nlp/Entity_Linking_Medical.ipynb
A few pip dependency make problems but doesn't stop the executions, but then later one cell has a problem with the tensorboard module.
This cell:
```py
# Initialize the trainer and model
trainer = Trainer(**cfg.trainer)
exp_manager(trainer, cfg.get("exp_manager", None))
model = nemo_nlp.models.EntityLinkingModel(cfg=cfg.model, trainer=trainer)
```
produces ERROR:
```py
