### Swedish-specific Transformer models

The code for calculating the number of parameters (comes from [this thread](https://github.com/huggingface/transformers/issues/1479)):

- PyTorch: `sum(p.numel() for p in model.parameters() if p.requires_grad)`

- TensorFlow: `np.sum([np.prod(v.shape) for v in tf.trainable_variables])`
