install

$ pip install jamba

usage

# Import the torch library, which provides tools for machine learning
import torch

# Import the Jamba model from the jamba.model module
from jamba.model import Jamba

# Create a tensor of random integers between 0 and 100, with shape (1, 100)
# This simulates a batch of tokens that we will pass through the model
x = torch.randint(0, 100, (1, 100))

# Initialize the Jamba model with the specified parameters
# dim: dimensionality of the input data
# depth: number of layers in the model
# num_tokens: number of unique tokens in the input data
# d_state: dimensionality of the hidden state in the model
# d_conv: dimensionality of the convolutional layers in the model
# heads: number of attention heads in the model
# num_experts: number of expert networks in the model
# num_experts_per_token: number of experts used for each token in the input data
model = Jamba(
    dim=512,
    depth=6,
    num_tokens=100,
    d_state=256,
    d_conv=128,
    heads=8,
    num_experts=8,
    num_experts_per_token=2,

# Perform a forward pass through the model with the input data
# This will return the model's predictions for each token in the input data
output = model(x)

# Print the model's predictions
