from callonce import callonce


@callonce
def _return_true() -> bool:
    return True


def _call_return_true():
    return _return_true()


def _call_return_true_3times():
    return _return_true(times=3)


def test_call_once():
    assert _call_return_true() == True
    assert _call_return_true() == None


def test_call_3times():
    assert _call_return_true_3times() == True
    assert _call_return_true_3times() == True
    assert _call_return_true_3times() == True
    assert _call_return_true_3times() == None

We offer a printonce function for easy debug in deep learning model, e.g., PyTorch. You don't have to remove the printonce when training the model in loop because the shape will be printed only once.

from callonce import printonce
from torch import nn

class Net(nn.Module):

    def __init__(self):
        self.linear = nn.Linear(4, 8)

    def forward(self, x):
        printonce('x:', x.shape)
        y = self.linear(x)
        printonce('y:', y.shape)
        return y
