Repost : Get 404 client error when I execute example in /blob/main/tutorials/nlp/Relation_Extraction
Maybe I misclick some button, so t post message again and give more detail

Describe the bug

In website [https://github.com/NVIDIA/NeMo/blob/main/tutorials/nlp/Relation_Extraction-BioMegatron.ipynb，](https://github.com/NVIDIA/NeMo/blob/main/tutorials/nlp/Relation_Extraction-BioMegatron.ipynb%EF%BC%8C) I run the code step by step, and i get the 404 client error on the last line of chapter "[Setting up a NeMo Experiment](https://github.com/NVIDIA/NeMo/issues/url)"

Steps/Code to reproduce bug

model = nemo_nlp.models.TextClassificationModel(cfg=config.model, trainer=trainer) in chapter "Setting up a NeMo Experiment"

Environment overview (please complete the following information)

    Method of NeMo install: Google Colaboratory,

Environment details

If NVIDIA docker image is used you don't need to specify these.
Otherwise, please provide:

    python 3.7.13
    pytorch 1.10.0
    cuda 11.1
