在Pytorch中计算自己模型的FLOPs方式

pip install thop

from torchvision.models import resnet50from thop import profile
model = resnet50()
flops, params = profile(model, input_size=(1, 3, 224,224))

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