UPDATE:
This seemed to call the original model, nit my configured one.
This is what im getting for the initialisation
[INFO|configuration_utils.py:553] 2021-05-04 13:19:23,488 >> Model config BertConfig {
  "architectures": [
    "BertForQuestionAnswering"
  ],
  "attention_probs_dropout_prob": 0.1,
  "gradient_checkpointing": false,
  "hidden_act": "gelu",
  "hidden_dropout_prob": 0.1,
  "hidden_size": 768,

  "transformers_version": "4.6.0.dev0",

But the “num_hidden_layers” should be 10 according to my configuration
