This tool(calflops) is designed to compute the theoretical amount of FLOPs(floating-point operations)、MACs(multiply-add operations) and Parameters in all various neural networks, such as Linear、 CNN、 RNN、 GCN、Transformer(Bert、LlaMA etc Large Language Model)，even including any custom models via torch.nn.function.* as long as based on the Pytorch implementation. Meanwhile this tool supports the printing of FLOPS, Parameter calculation value and proportion of each submodule of the model, it is convient for users to understand the performance consumption of each part of the model.
Latest news, calflops has launched a tool on Huggingface Space, which is more convenient for computing FLOPS in the model of 🤗Huggingface Platform. Welcome to use it:https://huggingface.co/spaces/MrYXJ/calculate-model-flops
For LLM, this is probably the easiest tool to calculate FLOPs and it is very convenient for huggingface platform models. You can use calflops.calculate_flops_hf(model_name) by model_name which in huggingface models to calculate model FLOPs without downloading entire model weights locally.Notice this method requires the model to support the empty model being created for model inference in meta device.
from calflops import calculate_flops_hf
model_name = "meta-llama/Llama-2-7b"
access_token = "..." # your application token for using llama2
flops, macs, params = calculate_flops_hf(model_name=model_name, access_token=access_token) # default input shape: (1, 128)
print("%s FLOPs:%s MACs:%s Params:%s \n" %(model_name, flops, macs, params))If model can't inference in meta device, you just need assign llm corresponding tokenizer to the parameter: transformers_tokenizer to pass in funcional of calflops.calculate_flops(), and it will automatically help you build the model input data whose size is input_shape. Alternatively, you also can pass in the input data of models which need multi data as input that you have constructed.
In addition, the implementation process of this package inspired by ptflops、deepspeed、hf accelerate libraries, Thanks for their great efforts, they are both very good work. Meanwhile this package also improves some aspects to calculate FLOPs based on them.
pip install --upgrade calflopsAnd you also can download latest calflops-*-py3-none-any.whl files from https://pypi.org/project/calflops/
pip install calflops-*-py3-none-any.whlIf model has only one input, you just need set the model input size by parameter input_shape , it can automatically generate random model input to complete the calculation:
from calflops import calculate_flops
from torchvision import models
model = models.alexnet()
batch_size = 1
input_shape = (batch_size, 3, 224, 224)
flops, macs, params = calculate_flops(model=model,
input_shape=input_shape,
output_as_string=True,
output_precision=4)
print("Alexnet FLOPs:%s MACs:%s Params:%s \n" %(flops, macs, params))
#Alexnet FLOPs:4.2892 GFLOPS MACs:2.1426 GMACs Params:61.1008 M If the model has multiple inputs, use the parameters args or kargs, as shown in the Transfomer Model below.
No need to download the entire parameter weight of the model to the local, just by the model name can test any open source large model on the huggingface platform.
from calflops import calculate_flops_hf

print("%s FLOPs:%s MACs:%s Params:%s \n" %(model_name, flops, macs, params))You can also use this model urls of huggingface platform to calculate it FLOPs.

Notations:
number of parameters (Params), number of multiply-accumulate operations(MACs),
number of floating-point operations (FLOPs), floating-point operations per second (FLOPS),
fwd FLOPs (model forward propagation FLOPs), bwd FLOPs (model backward propagation FLOPs),
default model backpropagation takes 2.00 times as much computation as forward propagation.
Total Training Params: 9.4 B
fwd MACs: 1.12 TMACs
fwd FLOPs: 2.25 TFLOPS
fwd+bwd MACs: 3.37 TMACs
fwd+bwd FLOPs: 6.74 TFLOPS
-------------------------------- Detailed Calculated FLOPs Results --------------------------------
Each module caculated is listed after its name in the following order:
params, percentage of total params, MACs, percentage of total MACs, FLOPS, percentage of total FLOPs
Note: 1. A module can have torch.nn.module or torch.nn.functional to compute logits (e.g. CrossEntropyLoss).
They are not counted as submodules in calflops and not to be printed out. However they make up the difference between a parent's MACs and the sum of its submodules'.
2. Number of floating-point operations is a theoretical estimation, thus FLOPS computed using that could be larger than the maximum system throughput.

There are some model uses that require an application first, and you only need to pass the application in through the access_token to calculate its FLOPs.

Meanwhile, by setting the parameter print_detailed=True which default to True, the calflops supports the display of the calculation results and proportion of FLOPs、MACs and Parameter in each submodule of the entire model, so that it is convenient to see the largest part of the calculation consumption in the entire model.
How to make output format more elegant
You can use parameter output_as_string、output_precision、output_unit to determine the format of output data is value or string, if it is string, how many bits of precision to retain and the unit of value, such as FLOPs, the unit of result is "TFLOPs" or "GFLOPs", "MFLOPs".How do deal with model has multiple inputs
The calflops support multiple inputs of model, just use parameter args or kwargs to construct multiple inputs can be passed in as model inference.How to calculate the results of FLOPS include forward and backward pass of the model
You can use the parameter include_backPropagation to select whether the calculation of FLOPs results includes the process of model backpropagation. The default is False, that is result of FLOPs only include forward pass.In addition, the parameter compute_bp_factor to determine how many times backward as much computation as forward pass.The defaults that is 2.0, according to https://epochai.org/blog/backward-forward-FLOP-ratio
How to calculate FLOPs for only part of the model module
You can use the parameter ignore_modules to select which modules of model are ignored during FLOPs calculation. The default is [], that is all modules of model would be calculated in results.How to calculate FLOPs of the generate function in LLM
You just need to assign "generate" to parameter forward_mode.calflops.calculate_flops()

We can draw some simple and interesting conclusions from the table above:
-
The chatglm2-6b in the model of the same scale, the model parameters are smaller, and FLOPs is also smaller, which has certain advantages in speed performance.
-
The parameters of the llama1-7b, llama2-7b, and llama2-7b-chat models did not change at all, and FLOPs remained consistent. The structure of the model that conforms to the 7b described by meta in its llama2 report has not changed, the main difference is the increase of training data tokens.
-
Similarly, it can be seen from the table that the chinese-llama-7b and chinese-llama-plus-7b data are also in line with cui's report, just more chinese data tokens are added for training, and the model structure and parameters do not change.
