Unofficial implementation of Perceiver IO: A General Architecture for Structured Inputs & Outputs

Usage

import torch

from src.perceiver.decoders import PerceiverDecoder
from src.perceiver.encoder import PerceiverEncoder
from src.perceiver import PerceiverIO


num_latents = 128
latent_dim = 256
input_dim = 64

decoder_query_dim = 4


encoder = PerceiverEncoder(
    num_latents=num_latents,
    latent_dim=latent_dim,
    input_dim=input_dim,
    num_self_attn_per_block=8,
    num_blocks=1
)
decoder = PerceiverDecoder(
    latent_dim=latent_dim,
    query_dim=decoder_query_dim
)
perceiver = PerceiverIO(encoder, decoder)

inputs = torch.randn(2, 16, input_dim)
output_query = torch.randn(2, 3, decoder_query_dim)

perceiver(inputs, output_query)  # shape = (2, 3, 4)

    Issue related to LayerNorm

    Hello, man. First of all thank for your effort a lot. I can see that It was taken your time quite much to write a clear code. How ever, I just have a small question about Cross Attention class:

            self.kv_layer_norm = nn.LayerNorm(kv_dim)
            self.q_layer_norm = nn.LayerNorm(q_dim)
            self.qkv_layer_norm = nn.LayerNorm(q_dim)
    

    When I integrated the repository to my program as the last layer . The outputs of these LayerNorm were always 0. When I removed these Norm layers, The code run pretty well but much worse than the simple method (let's say simply concatenate the inputs and queries). p/s: To be more specific, My queries and inputs were taken from 2 separated nets. Do you have any idea about it? Once again, thank you for your great work a lot.

    Comparison with perceiver-pytorch?

    How does this repository compare with https://github.com/lucidrains/perceiver-pytorch ?

    Would you have any interest in generalizing and integrating the two implementations together?

    in the referenced line self.scale should be multiplied instead of the divide, since it's defined as self.scale = self.qk_head_dim ** -0.5. The correct expression should be attention = (q @ k.transpose(-2, -1) * self.scale)
