WebThis logical split is done by partitioning the input data as well as the Linear layer weights uniformly across the Attention heads. We can achieve this by choosing the Query Size as below: Query Size = Embedding Size / Number of heads (Image by Author) In our example, that is why the Query Size = 6/2 = 3. WebApr 5, 2024 · So, for example I have: batch_size = 1 sequence_length = 12 embed_dim = 512 (I assume that the dimension for ```query```, ```key``` and ```value``` are equal) Then the shape of my query, key and token would each be [1, 12, 512] We assume we have two heads, so num_heads = 2 This results in a dimension per head of 512/2=256. hertz on charlotte pike in nashville
