trt-engine-explorer notebook fails at display_df

Description

I am trying to follow this tutorial for my model:

https://github.com/NVIDIA/TensorRT/blob/main/tools/experimental/trt-engine-explorer/notebooks/tutorial.ipynb

The command:

display_df(plan.df)

Generates a huge error output ending with "RecursionError: maximum recursion depth exceeded while calling a Python object":

Exception on /dtale/iframe/1 [GET]

It's worth to mention that at the same time jupyter kernel outputs an error message:

Start with tools/experimental/trt-engine-explorer/notebooks/tutorial.ipynb and reproduce the display_df(plan.df) failure in the reported Python 3.8 virtualenv. Review the complete error.log and the Jupyter, Flask, and D-Tale traceback; done means the tutorial displays the dataframe without the recursion error.
