   import torch

if name == "main": lamda_base = LaMDA( num_tokens = 20000, dim = 512, dim_head = 64, depth = 12, heads = 8 )

lamda = AutoregressiveWrapper(lamda_base, max_seq_len = 512)

tokens = torch.randint(0, 20000, (1, 512)) # mock token data

logits = lamda(tokens)

print(logits)

# Publishing

Hi @Aleksandar1932 ,

I was just looking into Poetry for package management the other day, so this pull request comes at the perfect time. I have previously used Twine and setup tools.

I will further review the Poetry documentation over the week and then merge your Pull Request.

Thank you,

Enrico
