How to use

  • Basic usage

    from torchvision.models import resnet50
from thop import profile
model = resnet50()
flops, params = profile(model, input_size=(1, 3, 224,224))

  • Define the rule for 3rd party module.

    class YourModule(nn.Module):
    # your definition
def count_your_model(model, x, y):
    # your rule here
flops, params = profile(model, input_size=(1, 3, 224,224), 
                        custom_ops={YourModule: count_your_model})
