Usage

There are several ways to run the Falcon Mamba 7B model, depending on the hardware available to you (CPU or GPU). Below, we will outline how to set it up.

Using the Pytorch Model

Make sure you have the latest version of the transformers library. Here are the steps for both CPU and GPU setups:

Running the Model on a CPU

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("tiiuaefalcon-mamba-7b-pre-decay")
model = AutoModelForCausalLM.from_pretrained("tiiuaefalcon-mamba-7b-pre-decay")

input_text = "Question: How many hours in one day? Answer:"
input_ids = tokenizer(input_text, return_tensors="pt").input_ids
outputs = model.generate(input_ids)

print(tokenizer.decode(outputs[0]))

Running the Model on a GPU

# pip install accelerate
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("tiiuaefalcon-mamba-7b-pre-decay")
model = AutoModelForCausalLM.from_pretrained("tiiuaefalcon-mamba-7b-pre-decay", device_map="auto")

input_text = "Question: How many hours in one day? Answer:"
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to("cuda")
outputs = model.generate(input_ids)

print(tokenizer.decode(outputs[0]))

Analogy for Understanding Model Execution

Think of the Falcon Mamba model as a highly skilled chef in a kitchen. The kitchen represents your computing environment (CPU or GPU), and the ingredients (input text) are what you need to prepare a delicious meal (output text). If you have a well-equipped kitchen (GPU), the chef works quickly and efficiently to whip up the meal. However, in a smaller kitchen (CPU), the chef still produces great food, but it may take longer to finish the same dish. Choosing the right kitchen setup can greatly influence your cooking (model execution) time and results!

Training Details

Falcon-Mamba has been trained on approximately 5,500 GT mainly sourced from Refined-Web. The training involved a multi-stage strategy that enhanced its context length capabilities and improved the complexity of the datasets used.

Evaluation

The Falcon Mamba model can achieve performance metrics comparable to other transformer models, utilizing optimized kernels for enhanced throughput. To ensure optimal performance, install the Mamba kernels with the command below:

pip install causal-conv1d=1.4.0 mamba-ssm

Troubleshooting

If you run into issues while using the Falcon Mamba 7B, consider the following troubleshooting ideas:

• Ensure you have installed all prerequisite packages such as transformers and accelerate.
• Check if your device has sufficient resources (GPU/CPU) to handle the model.
• Verify that you are using the correct model paths and input formats.
