+
+This <a href="https://arxiv.org/abs/2203.09795">paper</a> propose parallelizing multiple attention and feedforward blocks per layer (2 blocks), claiming that it is easier to train without loss of performance.

+You can try this variant as follows

+```python
+import torch

+
+v = ViT(
+    image_size = 256,
+    patch_size = 16,
