Model converted by the [`transformers`' `pt_to_tf` CLI](https://github.com/huggingface/transformers/blob/main/src/transformers/commands/pt_to_tf.py). All converted model outputs and hidden layers were validated against its Pytorch counterpart.

Maximum crossload output difference=3.171e-05; Maximum crossload hidden layer difference=5.812e-03;
Maximum conversion output difference=3.171e-05; Maximum conversion hidden layer difference=5.812e-03;
